Google was pretty confident about the camera.
Brian Rakowski, the company's vice president of product development, called it the best in mobile devices, and DxOmark gave Google phones an 89 score, 2 points higher than the iPhone 7. "It's not only best camera, which we have ever made, is the best camera ever made,” said Rakowski. Pretty self-confident, given that Apple and Samsung have been leading the mobile photography market so far.
As our camera tests show, Google was right, and in many cases the Pixel's camera is on par or even better than its closest competitors.
Dynamic Range
It's worth starting with dynamic range, as this is the main selling point of the Pixel. When it comes to shooting in good light conditions, the Google smartphone loses less detail. In the example below, you can see that the white flowers are a little blurry on , while on the iPhone 7 the picture turned out to be completely cloudy.
Unfortunately, the Pixel doesn't handle shadows as well. In this case, the iPhone 7 captures more detail, while the Galaxy S7 and Pixel produce sharper shots that are great for instant Instagram posting. Photos taken on the iPhone traditionally need a little post-processing.
Colors
The color reproduction on the iPhone 7 is softer, the colors are natural. The Pixel suffers from oversaturated greens, while the Galaxy S7 suffers from blues and blacks. Like the Samsung, the colors of the Google Phone aren't as natural, but there's no clear winner here, as it all depends on shooting conditions and personal preference.
Detail (zoom)
Photos on the Google Pixel are sharper than on the S7, which in turn produces sharper pictures than the iPhone 7. This may be due to the fact that both Android smartphones give photos post-processing, while the iPhone shoots "as is" .
The photos below are zoomed to 100%, and you can clearly see that the Google smartphone gives a much more detailed result than the Galaxy S7 and, even more so, the iPhone 7. At the same time, artifacts are visible in the JPEG file (especially on the green sheet on top). On the iPhone 7, the image turned out to be completely blurry.
Overall, the Google Pixel undeniably takes the most detailed photos, but the difference is hardly noticeable. Just be aware that the machine will give you a few extra blades of grass or a sharper line on a building in the distance.
low light
This is one area where the Pixel lags behind its competitors. At first glance, it seems that the result is comparable to the iPhone 7 and samsung galaxy S7, but a more detailed comparison suggests otherwise. The photo shows unwanted noise and blur. This is manifested even not in conditions of complete darkness, but at twilight.
An example just after sunset:
Front-camera
Google has said very little about the front camera, but today its characteristics and quality are very important. For most users, the selfie camera is even more important than the main one in everyday use.
The color reproduction on the Samsung front camera is the most natural, the iPhone is yellow, and on the Pixel the images are bluish. This year, Apple increased the resolution of the front camera, but the viewing angle is much wider on the S7 and Pixel. In addition, Google offers as much as 8 MP for selfies, but there is no front-facing flash for photographing in the dark.
Speed
It should be noted right away that the cameras work very quickly on all three devices, but the launch itself is implemented somewhat more conveniently by Samsung and Google. On the iPhone, you need to swipe to launch the camera from the lock screen, on the Galaxy S7 you can simply double-tap the Home button from anywhere in the system, in the case of the Pixel, you need to double-tap the power button. But in this case, the advantage is clearly on the side of the Korean company thanks to the combination of quick launch, quick camera app and instant autofocus.
Software
The built-in camera app is not bad on three smartphones. In most cases, you won't need to download third-party programs for advanced settings. The Korean flagship has the largest selection of options. Google Camera cannot boast of wide functionality, just like Apple's solution. Moreover, in order to change the settings in the iPhone camera, you need to go into the system settings every time, which is completely inconvenient.
Each device offers different shooting modes, such as panorama, time lapse or HDR. As for the latter, it's a matter of taste, but on Pixel it's too "aggressive", although in some situations the photos turn out much better than those offered by Apple or Samsung.
Video
Like any modern smartphone, Google Pixel can shoot 4K video and has a slow motion mode at 240 frames per second, however, then the resolution will be only 720p. Video quality is generally comparable, but there is a difference in stabilization.
iPhone 7 and Galaxy S7 have optical image stabilization that works whether you're shooting photos or videos. OIS helps improve quality in low light and reduce camera shake in daylight. Digital stabilization on a smartphone from Google only works with video. The picture on the Pixel is smoother, but sometimes the video can stutter to compensate for shaking. Perhaps the search giant will find a way to fix this problem, but everything else works surprisingly well.
Focal length/depth of field
Google didn't mention the exact specs, but the Google Phone's camera angle is the widest. This is good if you want to get more objects into the frame, but do not forget that the wider the angle of view, the closer you need to get close to objects. For reference, the focal length of the Samsung flagship is 26 mm, which is only slightly inferior to the Pixel.
Samsung offers f/1.7, Apple f/1.8, and Google f/2.0. In theory, this means that the S7's camera will capture more light, resulting in good photos in low light. It also means a blurrier background. In practice, it's hard to see the difference between the depth of field of the iPhone 7 and Galaxy, but the Pixel falls short in this parameter.
Not to mention the dual-camera iPhone 7 Plus, which was not included in the test. The fact is that Apple's 5.5-inch phablet has two camera lenses with different focal lengths. The second camera serves just to achieve the bokeh effect, as on SLR cameras. Therefore, a direct comparison does not make any sense.
Galaxy S7 and S7 Edge smartphones - flagships model range Samsung co stylish design and a great camera. We will focus on the photography capabilities of the Galaxy S7 and S7 Edge in our review. We tested both smartphones - Galaxy S7 and S7 Edge. They have the same cameras, so pictures and videos are no different. If you are thinking about which model to choose, Galaxy S7 or S7 Edge - hold them in your hands in the showroom, think about which model you need: the more affordable and practical S7 or the stylish S7 Edge with a curved screen.
The main difference is the screen. Both models have an AMOLED touch screen. The Galaxy S7 has a 5.1-inch screen, while the S7 Edge has a 5.5-inch screen. The screen resolution of both smartphones is the same - 2560x1440 pixels per inch.
Read more about the specifications of the Galaxy S7 and S7 Edge.
And today we will talk in detail about the camera of smartphones Galaxy S7 and S7 Edge. The main camera has a resolution of 12 MP, optics with a constant aperture of F / 1.7 and an optical image stabilization system.
The resolution of the matrix compared to the camera of the smartphone Galaxy S6 has decreased from 16 to 12 megapixels! But at the same time, the S7 began to shoot much better. What is the secret? Secret in larger size sensor and the new Dual Pixel autofocus system. Each point is divided into two independent photodiodes, one of them is responsible for image formation, and the other for fast and accurate phase detection autofocus. The result - the quality of photos and videos is noticeably better than the S6.
The front cameras in the Galaxy S7 and S7 Edge have a resolution of 5 megapixels, and optics with a constant aperture of F / 1.7. For a Skype conversation and a selfie, the resolution is more than enough.
How does the camera shoot? Let's see some shots!
The main advantage of the Galaxy S7 and S7 edge is the good quality of shooting in low light conditions. Here, the optical image stabilizer comes in handy - the pictures come out clear without blurring.
The camera's exposure meter is accurate, and the balance between shadows and highlights is almost always perfect. In auto white balance mode, the camera almost never makes mistakes, and if this happens, it is very rare. The pictures delight with excellent sharpness over the entire area of the frame, the colors look natural: the camera shoots very truthfully, you look at the photo and remember, yes, that's exactly how it was in reality. All these advantages allow us to confidently call the Galaxy S7 camera one of the best in modern smartphones.
Pro mode
Experienced amateur photographers will appreciate the Pro mode: you can control all shooting parameters and save pictures in DNG format. The pictures can then be processed to your taste in a graphic editor. Of course, not everyone will take things so seriously. But if you're serious about photography and want your best shots, Pro mode is for you!
Geotagging
Galaxy S7 and S7 Edge allow you to save geotags, this is a very convenient feature, you can always understand where the photo was taken. By default, geotags are enabled, but you can disable them in the settings if you wish.
Portrait photography
We shoot portraits most of the time! With this task, the Galaxy S7 camera does an excellent job. Check out our example. The picture was taken from the Ferris wheel in Sokolniki Park in the evening at sunset. At this time, the light is soft and ideal for portraits. Pay attention to the faces, there are no highlights and shadows.
The second example is shooting on the veranda in a summer cafe. See how well the camera has done the foreground and background. Skin colors are natural. That's just the face in the shadows, but here Instagram filters will come to the rescue.
Selfie
This picture was taken on the front camera, it has a 5 megapixel matrix. The selfie turned out really well. Pay attention to the result of applying a filter that smoothes the skin of the face. In our example, it is very soft. But if desired, anti-aliasing can be adjusted to your taste.
selective focus
The “Selective Focus” scene program allows you to effectively blur the background or foreground to your taste. Settings can be adjusted after shooting! In the Galaxy S6, this feature has already been implemented and glitched. Alas, the glitches remain!
Snapshot in normal mode
In this picture, the focus is in the foreground, the background is blurred
Glitches are clearly visible in this picture. Don't care!!!
Object shooting
The Galaxy S7 is great at focusing on objects up close. We filmed an example in a cafe. Here is the general plan:
Here's a close-up of the cheesecake! By the way, delicious stuff!
day landscape
Shooting landscapes on the Galaxy S7 is a pleasure! This photo was taken at Chistye Prudy in Moscow. Look what a picture! Wide dynamic range, excellent detail in shadows and highlights.
Here is a shot of the Friendship of Peoples fountain at VDNKh. Yes, we were lucky with the weather, but the Galaxy s7 perfectly conveyed the mood of a summer day!
Look at the detail in the picture. And this shot was taken on a smartphone :)
Evening landscape
This shot was taken in Pro mode on a tripod. Since the smartphone has a professional mode, why not take pictures in good quality?
HDR
HDR will almost always make your landscape shots more expressive and natural. But there are situations when HDR must be turned on. Look at our example - we photographed the Church of St. Nicholas the Wonderworker near the Tverskaya Zastava. The temple was in the shade, in the normal shooting mode, the facade of the temple came out dark.
Turning on HDR is a completely different matter! Now the details in the shadows are worked out better.

The second example is a forest in cloudy weather. It's hard to get a balanced shot in this kind of lighting. The first frame - shooting in normal mode.
Original photo: https://cloud.mail.ru/public/HTEA/SHtoFRyaT
And here is HDR! Amazing. Pressed one button and what a wonderful result.

test video
With the photo we figured out, the Galaxy S7 was able to surprise us! And what about the video? Let's check!
Ducks Ultra HD 3840x2160
We shot these wonderful ducklings at Chistye Prudy in Moscow. Look how cute they are! We recorded this fragment in Ultra HD holding a smartphone in our hands.
Squirrel, shooting in Full HD
And here the shooting is already in Full HD. The quality is certainly worse, but for most tasks Full HD is enough. Look what a brave squirrel! Eats nuts right out of the hands of a child!
Swans, shooting in Full HD
Some scenes look much more spectacular in the video than in the photo! See what beautiful white swans live in Gorky Park in Moscow.
Rock musicians. Make the sound louder!
Galaxy S7 writes sound perfectly. We recorded the performance of street musicians. And they play really well!
time lapse
Galaxy S7 captures time-lapse in Full HD resolution perfectly. The most spectacular time-lapses are obtained in good weather, when there are white clouds in the sky. Fix the camera still and shoot videos for 10 minutes.
Time-lapse example
DNG Processing
As already noted, the Galaxy S7 allows you to shoot in DNG format. See what you can do with a photo by processing it in Lightroom. Of course, the Galaxy S7 is not a professional DSLR. But there are situations when you do not need to attract attention to yourself, but it is simply necessary to shoot the plot. Journalists often face this situation. So, with the Galaxy S7 in your hands, you will look like a curious tourist. No one will suspect that you actually have a high-quality camera in your hands that can shoot in RAW format :)
Example of processing DNG from the Galaxy S7 camera in Adobe Lightroom
You can try it yourself! Here are the original DNGs:
Summing up the results of testing
The Galaxy S7 and S7 Edge smartphones did an excellent job of capturing photos and videos. If you wanted to combine the purchase of a quality smartphone and an amateur camera, then the Galaxy S7 is a great choice! Feel free to buy Galaxy S7! Of course, smartphones are not budget. Look at the prices! Not cheap. But having bought a gadget, you will definitely not regret the money spent, the smartphone will delight you excellent quality assembly and of course, pictures and videos in excellent quality!
Of the shortcomings, perhaps, it is worth noting the lack of optical zoom. Galaxy S7 shoots so well that there is a desire to shoot all the scenes on it! We also scold the Selective focus mode. It's time to eliminate the glitches! The rest is nothing to complain about.

Part 2: Examining the screen, camera, battery life and other features in detail
We continue the story about the Samsung Galaxy S7 Edge. In the first part of the article, the performance of the device was tested in detail, and its design was also described. Now we will study other key aspects, first of all, the quality of the screen and camera, battery life. And finally, we will share with you the experience of using a smartphone in extreme conditions.
Screen
As we already noted in the first part of the article, in the Samsung Galaxy S7 Edge, the manufacturer decided to rely on the average screen size - less than in the Galaxy S6 Edge +, but more than in the Galaxy S6 Edge. At the same time, the resolution remained ultra-high (2560×1440). And visually, the screen really makes an excellent impression. Instrumental testing of the display was carried out by Alexey Kudryavtsev, editor of the "Projectors and TV" section. Below is his conclusion.
The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are no worse than those of the screen of the Google Nexus 7 (2013) (hereinafter simply Nexus 7). For clarity, here is a photo in which a white surface is reflected in the off screens (on the left is the Nexus 7, on the right is the Samsung Galaxy S7 Edge, then they can be distinguished by size):
The screen of the Samsung Galaxy S7 Edge is slightly darker (the brightness of the photos is 103 versus 111 for the Nexus 7, the glare curved edges of the tested screen are excluded) and does not have a pronounced tint. The ghosting of reflected objects on the screen of the Samsung Galaxy S7 Edge is very weak, which indicates that there is no air gap between the layers of the screen. Due to the smaller number of borders (glass/air type) with very different refractive indices, screens without an air gap look better in conditions of strong external illumination, but their repair in case of cracked external glass is much more expensive, since the entire screen has to be replaced. On the outer surface of the Samsung Galaxy S7 Edge screen there is a special oleophobic (grease-repellent) coating (effective, better than Nexus 7), so fingerprints are removed much more easily, and appear at a slower rate than in the case of ordinary glass.
When displaying a white field in full screen and with manual brightness control, its maximum value was 410 cd/m², the minimum was 1.6 cd/m². You also need to take into account the fact that in this case the smaller the white area on the screen, the lighter it is, that is, the actual maximum brightness of the white areas will almost always be higher than the specified value. As a result, readability during the day in the sun should be at a fairly good level. The reduced brightness level allows you to use the device without any problems even in complete darkness. Automatic brightness control works according to the light sensor (it is located to the left of the front speaker slot). You can make adjustments to how this function works by moving the adjustment slider. Next, for the three conditions, we present the screen brightness values for the three values of this setting - for 0%, 50% and 100%. In complete darkness in automatic mode, the brightness decreases to 1.6, 7.9 and 7.9 cd / m², respectively (the first is too dark, the second and third can be normal after adaptation of the eye), in an office lit by artificial light (approximately 400 lux) brightness is set to 1.6, 130 and 405 cd/m² (dark - just right - a little bright, which corresponds to the specified correction), in a bright environment (corresponds to lighting on a clear day outdoors, but without direct sunlight - 20000 lx or a little more) - rises to 520, 540 and 540 cd / m². These values are greater than the maximum with manual adjustment, and such brightness should definitely be enough to ensure that the image on the screen is well distinguished in any natural conditions. In general, the result of the automatic brightness adjustment function is as expected. Note that even with automatic brightness correction turned off in a dark environment, the smartphone does not allow you to set the brightness above 190 cd / m². At any level of brightness there is a significant modulation with a frequency of approximately 60 or 240 Hz. The figure below shows brightness (vertical axis) versus time (horizontal axis) for several brightness settings:
It can be seen that at maximum and close to it, the modulation amplitude is not very large, and as a result, there is no visible flicker. However, as the brightness decreases, modulation with a large relative amplitude appears. Therefore, the presence of such modulation can already be seen in the test for the presence of a stroboscopic effect or simply with a rapid eye movement. Depending on individual sensitivity, such flickering can cause increased fatigue.
This screen uses a Super AMOLED matrix - an active matrix on organic light emitting diodes. A full color image is created using subpixels of three colors - red (R), green (G) and blue (B), but there are twice as many green subpixels, which can be referred to as RGBG. This is confirmed by a fragment of a microphoto:
For comparison, you can see the gallery of microphotographs of screens used in mobile technology.
On the fragment above, you can count 4 green subpixels, 2 red (4 halves) and 2 blue (1 whole and 4 quarters), while repeating these fragments, you can lay out the entire screen without gaps and overlap. For such matrices, Samsung introduced the name PenTile RGBG. The manufacturer considers the screen resolution based on green subpixels, on the other two it will be two times lower. The location and shape of the sub-pixels in this variant is close to the case of the Samsung Galaxy S4 screen and some other newer Samsung devices (and not only) with AMOLED screens. This version of PenTile RGBG is better than the old one with red squares, blue rectangles and stripes of green subpixels. However, some uneven contrasting borders and other artifacts are still present. However, due to the very high resolution, they have minimal effect on image quality.
The screen has excellent viewing angles. True, the white color, when deviated even at small angles, alternately acquires a light blue-green and pinkish tint, but the black color remains just black at any angle. It is so black that the contrast setting is not applicable in this case. When viewed perpendicularly, the uniformity of the white field is excellent. For comparison, here are photos in which the screens of the Samsung Galaxy S7 Edge (profile Basic) and the second comparison participant, the same images were displayed, while the brightness of the screens was initially set to approximately 190 cd / m², and the color balance on the camera was forcibly switched to 6500 K. White field:
Note the excellent uniformity of brightness and hue of the white field (with the exception of darkening and changing hue towards the curled edges). And a test picture (profile Basic):
The color reproduction is good, the colors are moderately saturated, the color balance of the screens is slightly different. Note that in this case, the picture occupies the height (with this screen orientation) of the entire area available for displaying the image and goes to the curved edges of the screen, which leads to darkening and color distortion. Also, in the light, these areas almost always glare, which makes it even more difficult to view images displayed in full screen. And even the picture of films with an aspect ratio of 16:9 comes to bends, which greatly interferes with watching movies. The photo above was obtained after choosing a profile Basic in the screen settings, there are four of them:
Profile adaptive display differs in some kind of automatic adjustment of color rendering to the type of displayed image and environmental conditions, which is obtained by selecting the two remaining profiles shown below.
AMOLED movie:
Saturation and color contrast are markedly increased.
Photo AMOLED:
The saturation is still high, but the color contrast is closer to normal. Now at an angle of approximately 45 degrees to the plane and to the side of the screen (profile AMOLED movie). White field:
The brightness at an angle on both screens has noticeably decreased (in order to avoid strong darkening, the shutter speed is increased compared to previous photos), but in the case of Samsung, the drop in brightness is much less pronounced. As a result, with formally the same brightness, the screen of the Samsung Galaxy S7 Edge visually looks much brighter (compared to LCD screens), since you often have to look at the screen of a mobile device at least at a slight angle. And a test picture:
It can be seen that the colors have not changed much on both screens and the brightness of Samsung at an angle is noticeably higher. Switching the state of the elements of the matrix is \u200b\u200balmost instantaneous, but there may be a step at the front of the switch-on width of about 17 ms (which corresponds to a screen refresh rate of 60 Hz). For example, the dependence of brightness on time looks like this when moving from black to white and vice versa:
In some conditions, the presence of such a step can lead to plumes trailing behind moving objects. However, dynamic scenes in films on OLED screens are distinguished by high definition and even some “twitchy” movements.
For profiles Photo AMOLED and Basic the gamma curve constructed from 32 points with equal intervals over the numerical value of the gray tint did not reveal any blockage either in the highlights or in the shadows, and the exponent of the approximating power function is 2.14, which is slightly less than the standard value of 2.2, while the real gamma - the curve slightly deviates from the power dependence (in the captions in parentheses are the exponent of the approximating power function and the coefficient of determination):
For profile AMOLED movie the gamma curve has a pronounced S-shaped character, which increases the apparent contrast of the image, but in the shadows the distinguishability of shades is preserved.
Recall that in the case of OLED screens, the brightness of image fragments dynamically changes in accordance with the nature of the displayed image - it decreases for images that are generally bright. As a result, the resulting dependence of brightness on hue (gamma curve), most likely, does not correspond slightly to the gamma curve of a static image, since the measurements were carried out with sequential grayscale output almost on the entire screen.
Color gamut in profile case AMOLED movie very wide, it almost covers Adobe RGB coverage:
When choosing a profile Photo AMOLED coverage is pressed to the borders of Adobe RGB:
When choosing a profile Basic coverage is compressed to sRGB borders:
Without correction, the spectra of the components are very well separated:
In the case of a profile Basic with the maximum correction, the color components are already noticeably mixed with each other:
Note that on screens with a wide color gamut without proper color correction, normal images optimized for sRGB devices look unnaturally saturated. Hence the recommendation - in most cases, watching movies, photos and everything natural is better when choosing a profile Basic, and only if the photo was taken on an Adobe RGB setting does it make sense to switch the profile to Photo AMOLED. Profile AMOLED movie, despite the name, is the least suitable for watching movies and anything else.
The balance of shades on the gray scale is good. Profile color temperature AMOLED movie noticeably higher than 6500 K, in the remaining two it is close to 6500 K, while in a significant part of the gray scale this parameter does not change very much, which improves the visual perception of the color balance. The deviation from the blackbody spectrum (ΔE) remains below 10 units for most of the gray scale, which is considered a good indicator for a consumer device, and also does not change very much:
(The darkest areas of the gray scale in most cases can be ignored, since there the color balance does not matter much, and the measurement error of color characteristics at low brightness is large.)
Let's summarize. The screen has a very high maximum brightness and has excellent anti-glare properties, so the device can be used outdoors without any problems even on a sunny summer day. In complete darkness, the brightness can be reduced to a comfortable value. It is permissible (and in bright light it is necessary) to use the mode with automatic brightness adjustment, which works quite adequately. The advantages of the screen include a good oleophobic coating, as well as a color gamut close to sRGB and an acceptable color balance (when choosing a profile Basic). At the same time, let's recall the general advantages of OLED screens: true black color (if nothing is reflected on the screen), excellent white field uniformity, noticeably smaller than that of LCDs, and a drop in image brightness when viewed from an angle. The disadvantages include modulation of the screen brightness. Users who are particularly sensitive to flicker may experience fatigue as a result. However, overall the screen quality is very high. Separately, we note that from the point of view of image quality, curled edges are only harmful, since this design find introduces very noticeable color tone distortion and reduces brightness at the edges of the picture, and also leads to inevitable glare along at least one long side of the screen in ambient light conditions .
Video playback
We did not find an MHL interface, as well as Mobility DisplayPort, in this smartphone, so we had to limit ourselves to testing the output of video files on the screen of the device itself. To do this, we used a set of test files with an arrow and a rectangle moving one division per frame (see “Methodology for testing video signal playback and display devices. Version 1 (for mobile devices)”). Screenshots with a shutter speed of 1 s helped determine the nature of the output frames of video files with different parameters: the resolution varied (1280 by 720 (720p), 1920 by 1080 (1080p) and 3840 by 2160 (4K) pixels) and frame rate (24, 25, 30, 50 and 60 fps). In tests, we used the MX Player video player in Hardware mode. The test results are summarized in the table:
| File | Uniformity | Passes |
| 4K/30p | Okay | No |
| 4K/25p | Okay | No |
| 4K/24p | Okay | No |
| 1080/60p | Great | No |
| 1080/50p | Great | No |
| 1080/30p | Great | No |
| 1080/25p | Okay | No |
| 1080/24p | Great | No |
| 720/60p | Great | No |
| 720/50p | Great | No |
| 720/30p | Great | No |
| 720/25p | Great | No |
| 720/24p | Great | No |
Note: If both columns Uniformity and Passes green ratings are set, this means that, most likely, when watching movies, artifacts caused by uneven interleaving and dropping frames will either not be visible at all, or their number and visibility will not affect viewing comfort. Red marks indicate possible problems associated with the playback of the respective files.
According to the criteria for displaying frames, the quality of video files playback on the screen of the device itself is very good, since frames (or groups of frames) can be displayed with more or less uniform alternation of intervals and without frame drops. When playing video files with a resolution of 1920 by 1080 (1080p) on a smartphone screen, the image of the video file itself is displayed exactly along the border of the screen, going to the bends. The clarity of the picture is high, but not ideal, since there is no escape from interpolation to the screen resolution. However, for the sake of experiment, you can switch to the one-to-one mode by pixels, there will be no interpolation, but PenTile features will appear - the vertical world through the pixel will be in the grid, and the horizontal one will be a little greenish. This is true only for viewing test worlds; the described artifacts are absent on real frames. The brightness range displayed on the screen actually corresponds to the standard range of 16-235 - in the shadows and in the highlights, only a couple of shades merge with black and white, respectively.
The experience of using the Samsung Galaxy S7 Edge showed that the curved edges in no way harm the image when watching a movie - you soon forget about them altogether, and the headphones do an excellent job of outputting sound: even in the conditions of road noise at low volume, the speech of the heroes is legible, while your neighbors the film is not heard.
Camera
On the occasion of the release of the new flagship, Samsung decided to gather journalists and take them to the "nearest suburbs" so that they can appreciate the smartphone in harsh conditions, without being distracted by work, social networks and other machinations of dark forces. However, the nearest Moscow region, corresponding to the required harsh conditions, turned out to be the Karelian coast of the Kandalaksha Bay of the White Sea - in fact, the Arctic. There, our editor of the "Digital Photo" section, Anton Solovyov, tested the smartphone's camera. Below is his detailed report.
The Samsung Galaxy S7 Edge has an updated camera module within general program improvement of consumer qualities, as in the case of many other features of this model. The lens now has an aperture ratio of 1:1.7, the pixels on the sensor have become even larger and have reached a size of 1.4 microns (you can even remember the "famous" HTC ultra pixels), while each has become double for faster focusing. The number of pixels was reduced to 12 million, which is the golden mean in such a form factor (suffice it to recall the history of the development of compact 1 / 2.3 ″ cameras).
However, hardware innovations had little effect on the camera menu.

An interesting feature of the camera is the presence of a manual mode, in which it is possible to shoot in RAW. In general, manual mode, like RAW, on a smartphone are far from essential tools. Moreover, the manufacturer tries to hone and bring the auto mode to the maximum, and the built-in converter often works much more adequately than third-party ones, so in most cases it is more expedient to use it for shooting.
However, in difficult lighting conditions, white balance problems can occur, which are solved by manually setting the temperature.
RAW will also be a nice bonus for those who like to tinker with processing, but do not forget that to get it, you need to turn the corresponding toggle switch in the camera settings, which is active only in Pro mode and is periodically reset after walking through other modes.
Panoramas are well implemented in the camera. Moreover, the power reserve during wiring is enough for more than 360 degrees. In addition, in the panorama mode, you can get interesting compositions if everything you would like does not fit into the frame. However, it should be borne in mind that panoramas are less clear than simple shots. Unfortunately, the HDR mode does not work when shooting panoramas, but it would be very nice.
Keeping IP68 protection in mind, you don't have to worry about your smartphone if it falls into snow or water. And although the manufacturer does not offer to shoot underwater, it would be a shame to miss such a chance, because we tested it not just anywhere, but on the shores of the White Sea (more on our overall impressions of using a smartphone in extreme conditions will be discussed later). There were a lot of problems when shooting with a smartphone underwater: the sensor starts to go crazy, the volume buttons set to release are not very conveniently located, but the water is cold and salty. The first problem was solved by turning on the display after lowering it under water or by partial immersion, the second and third had to be endured, and the smartphone was “desalinated” after swimming in sea water had to be in the snow. He endured all these actions with dignity.

Since we are talking about convenience, it is worth noting the problems when shooting one completely standard hand. Since there was an Edge modification in use, sensitive edges had to be handled carefully. (In general, these "edges" often create some discomfort when used, although if you want, you can get used to them for the sake of design.) stops responding to pressure.

For such cases, you can use the volume buttons in the settings and use them as a shutter button. However, they are located in such a way that it will not be very convenient for right-handers, and it is difficult to compose a frame on the remaining third of the display. In vertical orientation, there are problems with the fact that part of the index finger periodically falls into the corner of the frame.

The last option: turn the smartphone over, taking it by the top so that the volume button is under the index finger. However, this is inconvenient from the point of view of general use - you still have to connect your second hand to turn it over. In addition, the smartphone is too thin and tends to slip out with such a grip, and the fingers of the right hand constantly fall into the lens.

Good sharpness across the field of the frame, and the numbers of cars are distinguishable at such a twilight time. |
 |
Good long-range sharpness. |
 |
There is not so much noise in the shadows, although the work of the noise reduction is visible. |
 |
The camera pays attention to small details. |
 |
Macro photography is good for the camera. |
 |
The camera does a good job of capturing details in fairly complex scenes. |
 |
With night shooting, the camera copes well, but only in manual mode. |
 |
|
 |
The sharpness across the field of the frame is not always uniform, but the blur zone at the top in this case can be attributed to composition problems. |
In addition to the test in real conditions, we tested the camera on a laboratory bench according to our methodology.
The camera turned out to be quite flagship, although a little raw, which, I would like to believe, will be fixed in serial firmware. First of all, quite obvious sharpening and the presence of blur zones in very unexpected parts of the frame are embarrassing. In addition, a slight soapiness is noticeable, which, however, we are already accustomed to with Samsung smartphones. Otherwise, the camera behaves very decently and allows you to take pictures at the level of a good compact, both from the technical side and from the artistic side.
As you can see from the graph, in terms of resolution, the camera is almost at the level of its predecessors, but the overall quality of the images has undoubtedly increased, albeit not by much.
Focusing in a smartphone is implemented so well that you stop paying attention to it. Double pixels, in fact, implement the principle of phase focusing, and their presence on the entire sensor area ensures good accuracy. It's hard to say if the camera focuses much faster compared to other smartphones, but there were no problems with focusing, waiting for focus, and misses during testing. In any case, in this regard, the use of the camera did not cause discomfort, so we can say that focusing is fast enough.
I would like to note video recording separately, because this time its implementation in a smartphone really does not raise any questions. There is practically no effect of "rolling shutter", and other artifacts. The image is stable, sharp, without twitches and ripples, despite only 30 fps. Focusing in movies is as fast as it is in stills.
The smartphone has a slow motion mode that allows you to record in 720p at 240 fps with sound. When viewing, you can slow down a certain fragment. Below is a video made up of various recordings taken on a smartphone during testing.
More examples of shooting on the Samsung Galaxy S7 Edge camera are presented below in the gallery.

Software and communications
Smartphone works on latest version Android OS - 6.0.1. On top of it, a proprietary Samsung shell is installed, optimized specifically for the Edge modification. We are talking about an auxiliary menu that can be pulled out from the right side, as well as the ability to use curved edges for color alerts.
By and large, there is nothing new here compared to previous Edge, and, frankly, we still feel that all these features are more of an artificial attempt to justify the presence of curved edges and make this design find at least somewhat useful, rather than really useful features. After all, hypothetically, the same thing could be done with a conventional screen.
A much more valuable innovation is an updated file manager. Now you can easily transfer files from your smartphone to a flash drive and back without any problems, you can delete unnecessary files both from a flash drive and from a microSD card.
As befits a flagship, the Samsung Galaxy S7 Edge supports all the latest technologies and communication standards, including Wi-Fi 802.11ac 5 GHz, LTE Cat.9, Bluetooth 4.2 LE, NFC, ANT+. The latter is valuable because it allows you to connect your smartphone with various fitness accessories (for example, chest heart rate monitors) using an energy-efficient protocol.
Also note that the smartphone supports two SIM-cards. At least that's what Samsung claims, but we haven't been able to verify it. In our copy (engineering sample), the slot did not allow inserting a second Nano-SIM, the space for it was slightly less than necessary. Apparently, it is necessary to attribute this to the features of an engineering sample. But if you buy a Samsung Galaxy S7 Edge in a showroom, ask a consultant to show you how and where to insert a second SIM card.
Autonomy and heating
The smartphone is equipped with a significantly more capacious battery than the Samsung Galaxy S6 Edge - 3600 mAh versus the previous 2600 mAh. Even the larger S6 Edge+ has only 3000 mAh.
Of course, this increase has had the most positive impact on battery life: the Samsung Galaxy S7 Edge is one of the leaders in this regard, and it is able to operate on battery even with average active use much longer than the standard time of one day.
With active photo and video shooting in one busy day, the smartphone sat down by about 50%, working in “airplane” mode and with automatic screen brightness. Under the same conditions, watching an MP4 movie loaded into the built-in memory drains the battery by about 10% every hour.
In addition, we tested the battery life of the smartphone according to our method, with the brightness set to 100 cd/m².
As you can see, the less stressful the scenario, the better the smartphone performs. So, in the gaming scene, it is inferior to the iPhone 6s Plus in terms of battery life, and in video playback it is superior. And finally, let's pay attention to the excellent result in the reading mode. By the way, among the Android smartphones that we have ever tested, the Samsung Galaxy S7 Edge is unrivaled in this scenario!
Below are thermal images of the back surface obtained after 10 minutes of running a battery test in the GFXBenchmark program (the lighter, the higher the temperature):
It can be seen that the heating is strongly localized above the center and close to the right edge, which apparently corresponds to the location of the SoC chip. According to the heat chamber, the maximum heating was 44 degrees (at an ambient temperature of 24 degrees), which is above the average value in this test for modern smartphones.
Separately, it is worth noting the speed of recharging the smartphone. The Samsung Galaxy S7 Edge supports QuickCharge fast charging technology and when using the supplied power supply (9V 1.67A) it is fully charged in about an hour and a half. The device charges up to 50% in 40 minutes, half an hour is enough to fill the battery by 38%, and 15 minutes - by 22%.
During charging, both the smartphone and the power supply heat up noticeably, but this does not go beyond comfortable values, that is, you won’t burn your hands.
In general, despite the situation with load modes, we can recognize the Samsung Galaxy S7 Edge as one of the best (if not the best) Android smartphone in terms of battery life. And, of course, the charging speed is a very big plus compared to the iPhone, since there are cases when you urgently need to recharge your smartphone, but you have only a few minutes - especially when traveling or if you forgot to charge your smartphone at night.
conclusions
Well, we carefully got acquainted with one of the main smartphone innovations of this year, tested it both in the laboratory and in real life (and under extreme conditions). Based on the results of studying the device, we can safely admit that at the moment this is the real pinnacle of “smartphone construction”. The device combines innovation, practicality and uncompromisingness in almost all respects. By the fourth model in the Edge line (and the third among the S Edge), Samsung found an almost perfect ratio of screen diagonal and body size, equipped the smartphone with support for memory cards and two SIM cards, and was also able to implement full-fledged moisture protection without sacrificing the dimensions of the device or external view (no plugs - hello Sony!). On top of that, the battery capacity has grown significantly, and now this is one of the best smartphones in terms of battery life.
The curvature of the screen and its functional application, of course, still remain controversial points (for the convenience of everyday use, this is more of a minus than a plus), but it cannot be argued that this feature makes the Samsung smartphone unique, which is perhaps really valuable in our clone time. And advanced photography capabilities and top performance make the new product an ideal choice for enthusiasts. Of course, all this could not but affect the cost: Samsung Galaxy S7 Edge with a price tag of 60 thousand rubles occupies the top price category. However, it is also cheaper than the iPhone 6s Plus, even with the smallest amount of internal memory. And therefore, it is a very, very formidable competitor to the flagship of the apple company.
Finally, we bring to your attention a video review, where we share the main impressions of the Samsung Galaxy S7 Edge and clearly demonstrate some of its features (including water resistance).
P.S. For an excellent combination appearance and design functionality (above all, the implementation of water resistance), we award the Samsung Galaxy S7 Edge with our Original Design editorial award:
The smartphone is not only one of the most powerful on Android, but also takes great photos and videos. Well, we are sharing with you colorful shots taken with it on the shores of the White Sea and talking about the features of the camera.
The function of quickly launching the camera works great (double-clicking on the Home button with the tap turned off): unlike many similar solutions, here it happens really quickly. As, in fact, focusing with a shutter for a couple. Processor power allows.
Even with a very meager level of lighting, the result will be quite digestible, and sometimes just gorgeous. From the strange: it is not clear where the purple halo came from in the photographs of an open flame (in simple terms - a fire). Although, to be fair, we must again say that in such darkness, few smartphones can take a picture like that.
Also, one cannot traditionally not urge the oversaturation of the picture, which comes at the expense of the naturalness of the colors. And paired with a Super AMOLED display, some shots look quite acidic. But to say that it is ugly is to dissemble. You can only show here that this is not entirely fair. Well, even in the S7 Edge, the rounded edges of the display sometimes get in the way of properly aligning the frame boundaries and the horizon.
Many creative modes correspond to flagship status, and they also work fine for the most part, and most importantly, they are not as whimsical to shooting conditions as is usually the case. Only the panorama let us down a bit: it didn’t work out to move the camera so smoothly and slowly that we could do without ugly splicing in the frame. Even though he seemed to be trying.
Unfortunately, our admin panel does not like panoramas 18112 x 2112 and weighing 55 MB, so the original can
In February 2016, the new flagship Galaxy S7 was shown. Among other advantages, manufacturers have focused on the new camera, which claims to be the best in the world among mobile devices. One of the proprietary chips was announced support for DualPixel technology, which allows you to focus almost instantly.
Not only the new focusing mechanism is different for the 2016 flagship. Samo software has undergone changes, having received advanced settings. The matrix is also different from the sensors in other smartphones. We will try to find out about all the features of the photographic part and its capabilities in order.
The S7 does not use the standard shooting application from Android 6, but its own, which is part of the TouchWiz shell. It differs from the stock one with richer settings and a redesigned interface. Exactly the same application was used in S6, S6 Edge and Note 5. At the top of the window there are buttons for settings, choosing the resolution and aspect ratio of the photo, flash and timer switches, HDR and a menu for selecting effects. Bottom - focus / shutter button, photo / video and main / front camera switches, icon for accessing the photo gallery.
When choosing modes, you can use the preset scenarios: auto, pro, selective focus, panoramic photo, animation, the ability to shoot stream directly to youtube, slow motion slowmo, virtual 360-degree shooting, food shooting and accelerated video shooting.
In Pro mode, manual tuning becomes available. You can independently control the white balance, ISO value, contrast, brightness, and shutter speed.
A distinctive feature of the smartphone, which brings it closer to full-fledged cameras, is the ability to save photos in RAW and JPG at the same time. The "raw" data from the matrix can be processed in Photoshop or another professional editor. This allows you to adjust colors, sharpness, white balance, and other image settings in a quiet environment on your computer to achieve the best possible quality.
Specifications
In the Galaxy S7, the photomodule is based on a matrix with a resolution of 12 MP. Depending on the release batch and modification (and there are only about 20 of them, for different markets and networks), the own Bright Cell S5K2L1 or Sony Exmor IMX260 module can be used. They have identical characteristics, and, very likely, are variations of the same model produced at different enterprises.
Despite its modest 12MP resolution by 2016 standards, the S7's camera has some advantages. First of all, these are the dimensions of the matrix: 1 / 2.5 "- usually such a diagonal corresponds to 16 MP. Due to the large matrix, the pixel was increased to 1.4 microns (instead of the standard 1.12 microns for S6). In addition, each of It features its own phase-detection autofocus sensor, a technology called Dual Pixel that was previously only used in SLR cameras.
Optics in the S7 has also changed in a positive direction. The aperture (aperture) of the lens has been improved from f/1.9 to f/1.7. The stabilization system provides protection against a trembling hand. During the day, there is practically no benefit from it (the frame is taken with an instant shutter speed), but in the evening the system helps to increase clarity. The flash looks somehow modest: it consists of a single diode that emits neutral white light.
There is practically no difference in photo quality from different matrices (Samsung and Sony) when viewed on a monitor. If you take photos on different versions of the Galaxy S7 under the same conditions, the comparison shows a minimal difference. It is only noticeable to the naked eye that the Samsung sensor observes the color temperature a little better, and the shots with Sony slightly go into warm shades in the evening (the shots turn a little yellow). But the Japanese matrix shows slightly better detail, which is noticeable when zooming in to 100%. Below are two shots on two Samsung Galaxy S7 smartphones with different matrices: at the top is a matrix from Samsung, at the bottom from Sony.
How the camera shoots in different modes
daytime landscape photography
S7 in daylight photography shows excellent results. It provides an acceptable level of detail even though the pixel count has been reduced. At the same zoom level, photos from the S7 look more "angular" than from the S6, but the contours of objects do not have the same blurs as their predecessor. It's hard to tell right away which of the two is the lesser of two evils, but the shots from the S7 look more attractive in this comparison.
Shot in good conditions
The dynamic range can be called rich (by the standards of mobile technology), in the bright sun the smartphone does not overexpose the sky, but the darker areas of the photo do not obscure. But it is not ideal if there are enough bright details and light tones in the frame - signs of flare appear. For example, the radiance of the sun, even partially caught in the lens, blinds the corner of the frame, filling it with white. These are nitpicks (not shooting against the sun is one of the first rules of a novice photographer), but the fact remains.
Sky focus shot
Shot with the sun in the frame
Tree focus shot
Daytime photography is not the trump card of the Galaxy S7 at all. And this is not because the matrix is bad (no, it shoots perfectly). Simply, this is a smartphone camera, but no more. It will not work to consider every leaf of a tree standing a couple of tens of meters away. Photos from some Meizu, Xiaomi for $200, or Samsung for $250 will look the same on the monitor screen. Excellent lighting conditions allow any more or less normal matrix to open up, minimizing competition.
Portrait photography and close-ups
Not so long ago, Xiaomi introduced the Redmi Pro camera phone, equipped with two matrices. The presentation focused on the great bokeh effect (blurring the background and sharp focus in the foreground). The smartphone was even compared with a $4,000 Canon professional DSLR to emphasize the “coolness” of the novelty. So, S7 can do the same without any second matrix. Close focus works very clearly, portrait photography is its strong point. Blurring the background beautifully, emphasizing the contrast, is not a problem at all.
Focus on the object near and blur the background
When shooting portraits from a couple of meters away, the sensor's capabilities are enough to take in most of the reflected light. Under such conditions, the sensor practically does not lather the skin on the face and transmits its details. If you use a tripod and set an increased shutter speed, the shots turn out great. With close shooting and portraits, the Samsung Galaxy S7 does an excellent job. In this mode, the benefits become more noticeable.
Shooting at dusk
In low light conditions (100-1000 Lux, like overcast or in a building), the advantages of the camera become more apparent. A decent-sized sensor captures more light, which makes the details of objects appear clearer. The flash mentioned above, despite only one LED, does its job in good faith. Objects in the foreground are highlighted with high quality, their contours are smooth and quite distinguishable.
If you do not shoot with the flash turned on automatically, by turning it off, near details become less clear. But that's only for the weak. room lighting. At dusk, the lack of sunlight does not interfere. Here lies the main advantage of the Samsung Galaxy S7 over cheaper devices. They are already starting to smear the contours, applying noise reduction, and the hero of the review still allows you to highlight the “ladders” of pixels in the photo - side effect from reduced resolution. That is, if the noise suppression system is connected, it is only superficially, without distorting the details.
When trying to take a picture of a neighboring house at dusk, the camera gives out “something that looks like real outlines”. “Soap” appears, clarity leaves much to be desired, but competitors cannot even do this, demonstrating incomprehensible spots when approaching a photo, under which it is difficult to guess the house. Here the score is a three with a slight minus, against the background of full-fledged devices, but 5 in comparison with smartphones.
Night shooting
You can get a high-quality frame at night only with a flash, and at close range. No matter how they sing about the Samsung S7 camera, this is just a smartphone, albeit an expensive one. Even a tripod and long exposure will not help to shoot the starry sky. A tiny (by the standards of DSLRs) matrix is beyond its power. In general, in auto mode at night, the camera is of no use, as in comparison with any other smartphone. You need a photo in the dark - only a SLR will help.
Another thing is a photo with a flash of nearby elements. The device will be able to take a picture of a company sitting by the fire. It will even (clear argument in defense) retain some kind of balance. The flame will not turn into an incomprehensible yellow spot, but will remain visible, but the faces, at the same time, will not turn into lifeless wax figures. So that's a plus here too.
On the Samsung Galaxy S7, you can get a decent shot under streetlights. The camera will also capture sunset or dawn, and even be able to convey many shades.
Frontalka
In addition to the main matrix, the Samsung S7 also has a good front camera. It is also not easy: at a resolution of 5 MP, aperture is also equal to f / 1.7 (like the main one). This is very good, as for the front camera. Due to the good light transmission, selfies are very detailed. Someone will not even like it: if you do not apply effects, then the device “spoils” the portrait. At an ultra-small distance (half a meter), in sunlight, every pimple, every mole becomes visible.
The background of the front camera is a little soapy (the focus is fixed, and it is set to the foreground), but within reason. Something like this was shot by the main matrix of the iPhone 4 in similar conditions, even if you do not take an amendment for the lack of autofocus from the hero of the review. The selfie camera also supports auto HDR.
Video filming
In terms of video shooting, the Samsung Galaxy S7 is also good. Supports 4K video recording at 30 FPS. But such a frame rate per second is provided only in good lighting, at dusk the frequency decreases.
The camcorder performs much better when shooting in FullHD. A frame rate of 60 FPS is sufficient for smoothness, while an optical stabilizer smooths out shaky handheld shooting. The sound is recorded in stereo, thanks to the presence of a second microphone. This is not Dolby Digital, but against the backdrop of Xiaomi with two microphones - heaven and earth.
If you reduce the resolution to HD 720p, you can do slow motion at 240 FPS. When viewed, such videos will play 8 times slower than they were filmed. This is not enough to capture the flap of an insect's wing (for this you need at least 1000 FPS), but it is quite possible to view slower phenomena and processes in detail.
Are there any drawbacks to the camera, as for a smartphone
The main disadvantages of the Samsung Galaxy S7 camera (in comparison with full-size cameras) are highlighted. This is a lack of detail, low light sensitivity at night, non-ideal dynamic range. Shooting video in 4K is noticeably inferior to video cameras (the same GoPro budget versions). But what if compared to smartphones, which is the Samsung Galaxy S7?
- Dynamic Range. There are no shortcomings here: modest against the background of DSLRs (in which the sun remains orange), but cool against the background of mobile phones. Only a few can do the same.
- Detailing. There are no benefits here. On a summer day, S7 can lose to a more budgetary 16 MP matrix (due to a smaller number of pixels), and in the evening, you can still watch “soap” or “ladder”.
- Focusing. Here, the Samsung S7 has no minuses, definitely. The focus is fast, the contrast between the central composition and the periphery is emphasized perfectly, everyone would like it.
- Evening shooting. In this regard, the Samsung Galaxy S7 camera is able to get ahead of rivals. An enlarged matrix of pixels and aperture catch light better, there are no minuses.
- Portrait. And there are no shortcomings in this nomination. Not a DSLR, but among smartphones, only the Nokia 808 (which is 100 years old, as it was discontinued) could do something better. This applies to both the main camera and the front camera (in which only models with the Sony IMX179 at 8 MP can compete with the S7).
Thus, we can state that the only thing where the Samsung Galaxy S7 camera may not be the best is the detailing of photos taken in bright daylight. Here, even a $200 Chinese with 16 MP can match. The only difference is that the percentage of successful photos from the S7 will be higher than that of the Chinese.
