How to Take Screen Samsung A8
Screen Galaxy A8 (2018)
Samsung Galaxy A8 (2018) received a 6-inch display. For comparison, the Galaxy A8 (2018) has 5.6 inches. The display is made using Super AMOLED technology, like all more or less worthy Samsung devices. It has a ratio of 18.5: 9 versus the classic 16: 9. The screen turned out to be elongated by reducing the frames to a minimum in the upper and lower parts of the gadget.
The display resolution is 1080×2220 pixels. In fact, this is Full HD (1920×1080) to which 150 pixels were added above and below. The pixel density of the display is 411 ppi. Galaxy A8 with a smaller diagonal has a density of 441 ppi. Visually, the difference between them is subtle. 411 ppi in any case means a high-definition display. This is more than most devices on the market, but it does not reach the flagships, which can boast of indicators above 500 ppi.
Subjectively, as in the case of the Galaxy A8, the screen of the A8 is excellent: there are rich colors, high brightness and real black.
Samsung Galaxy A8 (2018) allows for fine-tuning the display. It has several predefined profiles for adjusting color temperature and balance: basic, adaptive and custom. The main one has a color temperature value very close to 6500K, natural color. The adaptive temperature is higher. The colors are a little colder, but subjectively brighter. Also, the user can configure separately the parameters of each color at his discretion. In the settings there is a blue filter, as well as some adjustments to the touch surface, for example, blocking accidental clicks. The latter is useful in that it does not like to use a PIN code to unlock it.
Samsung Galaxy A8 (2018) with AMOLED screen supports Always On function. OLED screens do not have a backlight. Here, each pixel is lit individually. This allows you to constantly keep a couple of hundred pixels working on the display off, which display service information, such as a clock.
Always On is turned on in the display settings.
The user can display a different type of clock, calendar on the off display. Notifications can also be displayed here. Templates are also configured separately. Different colors can be used.
The display brightness of the Galaxy A8 (2018) was 523.57 cd / m 2. For comparison, Note 8 we intended 355.51 cd / m 2. And the Note 8 screen did not cause us problems in the bright sun, so the Galaxy A8 (2018) The display will be visible even better. Also, it should be noted that given the absolutely black OLED technology, the contrast is also “absolute”.
The color temperature display of the Samsung Galaxy A8 (2018) we measured for two profiles. The graphs are a little walk, like the Galaxy A8 (2018). The main profile showed a temperature value of about 6600-6700K. Adaptive closer to 7000K. The colors when using both profiles will be very close to natural.
The color gamut is characteristic of AMOLED. It is noticeably higher than the sRGB range.
Gamma curves deviate from the standard, especially in the middle range of brightness, but this cannot be recognized as a serious drawback.
The display supports 10 touches. It could not be otherwise.
As a result, the screen, both subjectively and objectively, is very good.
Galaxy A8 Camera (2018)
Samsung Galaxy A8 (2018), like all modern smartphones, has two cameras. However, there is a difference. The device, together with the A8 model (2018), as well as some models from other manufacturers, marks a new trend in mobile photography.
Previously, the rear camera was considered the main one. It was she who received all the major innovations, as well as the best sensors. Now there is a clear roll towards the selfie and the front camera.
As before, the matrix of the rear camera has large physical dimensions, which guarantees higher image quality. However, in A8 (2018), Samsung did not double it, but made it dual front. And this despite the fact that the Korean manufacturer has, in principle, few dual cameras!
In Note 8, the dual camera had the same sensors, but different optics, which provided 2x optical zoom. a useful option. In the Galaxy A8 (2018), the front camera has asymmetric sensors. One got a resolution of 16 megapixels, the other. 8. Some manufacturers have a similar scheme. The auxiliary sensor here is used to adjust the depth of field, and also possibly helps the device in face recognition.
The rear camera also has a resolution of 16 megapixels.
The disadvantage of both cameras can only be recognized as recording in Full HD format, although the capabilities of the hardware platform clearly allow recording 4Ks. However, here Samsung was clearly guided by marketing considerations in order to breed the devices on the market.
The camera interface of the Samsung Galaxy A8 (2018) is similar to how the cameras of other smartphones of the company are controlled, except that the front buttons have more buttons than the back ones.
To the right or bottom, depending on the orientation of the screen, there is a button for releasing photos and recordings. There is also a window in which a thumbnail of only the photograph taken is displayed. On the other hand, we see buttons for changing the camera, full screen mode, turning on the flash, and settings.
Galaxy A8 (2018) also has swipe functions that trigger filters and shooting modes. On the right swipe, a tab opens where you can select the shooting mode. There is a professional who allows you to adjust all the parameters. There is a special mode for shooting food. Hyperlapse allows you to take pictures after a certain period of time and glue them into animation and others. Left swipe causes a set of filters, but now there is a more interesting way to decorate a photo. stickers.
There are now two links in the camera interface. One activates the Bixby camera, the second. stickers. Both options enable AI. In the first case, you can stick a sticker on the image. It can be a copyright sign or just a funny picture. Also, using the option, you can paint on ears, horns, etc. to the person’s face.
Camera settings, as usual with Samsung, are not divided for the rear and front. In addition, there are few of them. The resolution of pictures and clips is selected in one screen for both cameras.
The front camera interface receives on the left side an additional virtual button. It is a kind of dotted circle. If activated, the Live Focus function appears. The second camera is activated, with which you can blur the background, leaving the face or object in the foreground sharp. The effect of volume is achieved, and in general the picture is more beautiful.
The front camera also has a swipe. There are few modes, but there is the opportunity to take a widescreen selfie. It’s a cross between a selfie and a panorama. Allows you to fit a large company or architectural object into the frame.
The maximum resolution of the main camera is 16 megapixels, while the aspect ratio is only 4: 3.
The main camera takes good pictures. Please note that when sticking a sticker, the size of the photo decreases.
The main camera can shoot Full HD.
The front camera can also take a 16-megapixel shot and it will also be 4: 3.
The front camera is clearly focused on selfies. Her general plans are blurry.
