Display Samsung Galaxy A5 (2017)
The screen of the Samsung Galaxy A5 (2017), as well as of its predecessor, is made by the technology Super AMOLED, which promises us a good color, acceptable brightness and true black. All this was in the Galaxy A5 (2016), and it's all here in the model of 2017.
The screen resolution of 1920x1080 pixels has not increased for the year. It gives the density of pixels 424ppi, which in general is quite good.
Also, Samsung has added the mode Always On. When the display is off, it continues to show the current time, date and battery level. The battery consumption is minimum, since the AMOLED technology makes it possible to use only a few tens of pixels required for the operation.
The screen has good vivid colors and excellent viewing angles, which is not always good: all people around will see what you are doing in your smartphone.
The subjective impressions are confirmed by the objective data. The screen brightness (white) amounted to 357.49 cd/m2, the brightness of black, as it should be in OLED - 0. Accordingly, the contrast ratio is apparently higher than that of any LCD display.
In the display settings, there are two main modes: basic and adaptive. In the former one the color coverage is approximately equal to the area of sRGB, even a little more. In the adaptive mode, the color coverage is much wider than that of the area, which is considered a standard.
When measuring the color temperature of the screen, the difference between the settings modes is not so noticeable. They are quite close to the natural temperature 6500K, but still above it. The main mode is a little below 7000K, the adaptive - above 7000K, but also not too much. In other words, in the second case the picture looks a little colder.
The gamma-curve of the main mode is almost identical to the reference one. The adaptive mode is a little higher in the middle, and it causes darkening of light colors in the image. However, much can be corrected by the display settings, which the Galaxy A5 (2017) has more than other smartphones.
Now the Galaxy A5 (2017) has a trendy "blue filter", which reduces the level of blue and has a positive effect on fatigue - it reduces. However, we would not use it, because the display acquires a yellowish shade. But, perhaps, it will be useful for long reading in the dark.
In addition to the main and adaptive display modes, there are also image and video modes, which adjust the screen automatically, so that the pictures and movie look in the best way. For each mode, the user can adjust the balance of RGB - red, green and blue colors. Besides, in the display settings there is a possibility of switching on and off the function of Always On. Also, it allows to order to the smartphone not to switch on the display if it is in the dark, that is in your pocket or a bag. It is important for devices of a large size.
The display recognizes 5 touches, as well as it was in the Galaxy A5 (2016), which once again confirms our conclusion about the software nature of the limits. Still the Galaxy A line should give in in something to the Galaxy S.
Cameras Samsung Galaxy A5 (2017)
The camera has been significantly improved in the Samsung Galaxy A5 (2017). Previously, the device possessed a photo module with the 13 megapixels resolution for the main camera and 5-megapixel for the front-facing one. Now two of the smartphone cameras are 16-megapixel. The trend reflects the selfie passion. In addition, according to the image quality, the front 16 megapixels are more "honest" than of most smartphones with the declared selfie camera. Both cameras can also shoot Full HD video.
The camera interface remains the same. On the first screen, we see buttons for shooting photos and video recording, as well as a window to display the gallery and preview image. In the other part of the display, we see virtual buttons for changing the cameras, flash control and calling setup. The face in the corner of the viewfinder calls the option of adjusting the complexion. By changing the white balance, you can achieve the best color.
The settings for both cameras are common. It is interesting that they are shown not in the camera’s interface, but in other phone settings. You can directly select resolution, set the timer, turn on video stabilization, geotagging, start recording by voice, gesture or the volume button.
Besides, there are two more tabs on the main camera screen. By swiping to the right, you can open a tab with the filters that are applied in real time to the image preview.
The left tab contains the recording modes, both for video and photos.
In addition to the automatic mode, the mode Pro is available. It makes possible to adjust ISO, white balance, exposure and other settings.
There are also other modes: panorama, slow motion, HDR, night and meal. The most interesting are slow motion and the food, which adds blur to the background. Besides, it is possible to change the white balance so that the images look better.
The front camera has the same interface and the same tabs. The adjustment of skin color is available too. On the right side, there are filters in real time. On the left, we can find only three modes: a self-portrait (auto), night and a wide self-portrait, which is a hybrid of selfie and panorama. It is not always possible to make selfie with a good background. Therefore, in this mode, we make selfie, move the phone to the right, to the left and get a picture with a wide field of view.
The main camera can shoot in different resolutions, as well as use a different aspect ratio. The maximum is reached at a ratio of 4:3.
As we can see, the pictures are of very good quality. Even with the use of zoom, the images are sharp enough, and this difference is not visible at all on the phone screen. In the dark, it is better to shoot with the flash, which works quite well.
With the help of the main camera of the Galaxy A5 (2016), you can shoot a video with the resolution up to Full HD. Ultra HD (4K) is kept for the flagships.
The camera records video well and, that is more important, makes a good sound. The video from the front seat of the car shows that the camera focuses quickly, adapts to the lighting etc.
The image resolution from the front camera and the choice of aspect ratio is the same as of the main one.
The image quality is much more interesting. It is easy to see how different the image sharpness on close-ups and photos with a general plan. We tried hard but failed to shoot a dull urban landscape from a loggia as sharply as the main camera. Apparently, the focus of the camera is fixed so as to guarantee the perfect selfie.
Similarly, the video, shot by the front camera, turned out to be blurry, not so sharp as made by the main one. The assumption about the shifted focus or its limited range to create a corresponding effect of the frame’s depth and blurring the background in selfie seems true. Usually, all cameras of this size are hyperfocal, that is, they achieve maximum depth of sharpness at a distance of 1-2 meters, so they do not have to focus when shooting landscapes. Here, it is obvious that there are settings to make the background blurred.
By the way, almost all of our observations are valid only when viewing images on a computer screen, whereas on AMOLED-display of the Samsung Galaxy A5 (2017), all the pictures look very good, and some of them are just perfect.
