Samsung Galaxy A9 (2018) review: the world’s first smartphone with 4 main cameras

Samsung Galaxy A9 (2018) review – Samsung is experimenting again with its smartphone lines and with the smartphones themselves. In recent years, the A-line has been an average in Samsung’s lineup, between the flagship S Note and the budget J. Some characteristics of the lines are also changing: earlier in the A-line there were smartphones with housings. made of glass and with protection against humidity. Now there is both glass and metal in a design close to the J-line. Which is not very encouraging – the line has lost its protection against moisture.

On the other hand, it seems that on A-line smartphones Samsung has decided to “test” new developments, which can be seen in a slightly modified form in future flagships. In particular, we are talking about the hero of today’s review, the Samsung Galaxy A9. It is the world’s first smartphone with a quadruple rear camera. Let’s try to understand why, how it works and in general what makes the new smartphone interesting.


What is that?

The Samsung Galaxy A9 (2018) is a 6.3 inch 18.5: 9 widescreen Infinity Android smartphone with a Qualcomm Snapdragon 660 processor, 6 GB of RAM and 128 GB of internal storage, a quad rear camera and a striking design.


Why is this interesting?

By far the most interesting feature of the Samsung Galaxy A9 (2018) is its main camera, which includes up to four modules, which is a record at the moment. Why so much? On paper it looks like this: the 24 MP main module with f / 1.7 aperture optics, a wide-angle module with a resolution of 8 MP and an f / 2.4 lens with a viewing angle of 120 °, a telephoto lens 10 MP with f / 2.4 aperture for 2x zoom and 5 MP module with f / 2.2 aperture for background blur. In theory it all makes sense, cameras for all occasions, but let’s see how it all works.

From a smartphone point of view, everything is more familiar: 6.3-inch SuperAMOLED display with an aspect ratio of 18.5: 9, rounded corners and a resolution of 2220 x 1080, without cutout. Inside is a good mid-range 2.2GHz Qualcomm Snapdragon 660 processor with Adreno 512 graphics, which is pretty confident in handling modern games.

They did not regret the memory: operational 6 or 8 GB, built-in – 128 GB. And to whom it will not seem enough – there is a separate slot for MicroSD. The smartphone has received all the necessary wireless interfaces: dual-band Wi-Fi, Bluetooth 5.0, NFC and an FM tuner. It is powered by an impressive 3800mAh battery and runs on Android 8.1 Oreo OS with a proprietary shell.


What’s in the box?

The Samsung Galaxy A9 (2018) comes in a relatively small white box with a photo of the smartphone itself. In addition, the box contains an Adaptive Quick Charging fast charger with support for Quick Charge 3.0, a USB Type-C cable, a clip for the SIM card tray, a wired in-ear headset (“plugs”) and documentation.


What does the Samsung Galaxy A9 (2018) look like?

The appearance of the Samsung Galaxy A9 (2018) is familiar to smartphones from the Korean electronics giant. Standard set: metal frame and front and rear glass. Up front there is a screen with rounded corners, a speaker, sensors and a front camera. Always on Display is supported. There is no Samsung logo on the front which will definitely appeal to a number of users. And there is no LED indicator, which is a shame.

Although Always on Display replaces it to some extent. The glass is rounded, the frames on the sides are very small. Above and below – also within reason. They are the same, which will delight the eye of a perfectionist:

The smartphone’s frame is rounded for a more comfortable grip, although it turned out to be quite slippery in itself. The layout of everything around the edges has been updated a bit. On the right is the volume and power control buttons, on the right is the button to launch the Bixby virtual assistant. He cannot be reassigned. At the bottom, there is an external speaker, microphone, USB Type-C connector, and 3.5mm headphone jack. Above, an additional microphone and tray.

The entire back panel is glass, slightly curved on the sides. Despite the presence of an oleophobic coating, impressions remain. This is the problem with all glass smartphones. Recently, “gradient” colors have become fashionable in the construction of smartphones. We just reviewed this option: the back cover smoothly changes from blue to green.

It looks interesting and quite original. There is also a pink version and a stricter black version. Almost in the middle of the back cover is the Samsung logo, above which is a fingerprint scanner. The main camera is located vertically in the upper left corner, so you will not be able to enter the lens instead of the scanner, even with a strong desire.

The same four-eyed main camera module is located in the corner. It protrudes slightly above the body, although this does not affect the convenience. Below is an LED flash:

The smartphone looks decent, well built and fits well in the hand, which is especially important with such a screen diagonal. Maybe this will seem slippery to someone. I think Samsung will release branded covers for this case.


What is the screen?

The smartphone has a 6.3-inch screen with an aspect ratio of 18.5: 9, rounded corners and a resolution of 2220×1080, the pixel density is around 392 ppi. A Samsung SuperAMOLED matrix with a Diamond PenTile subpixel arrangement is used. You might think that the resolution is not sufficient, given the type of matrix, but in reality there are no issues.

I couldn’t see any individual pixels, “scale” or something like that. Viewing angles are maximum, at certain angles the screen gives off a slightly green tint, which is usual for AMOLED matrices, as well as the “real” black color and maximum contrast. The stock of brightness is correct, the image remains readable in the street.

There are a lot of things in screen settings: adjust scale, font, text size, blue filter, auto brightness. In the always-on display settings, you can choose what exactly will be displayed, select the style and color of the clock, and configure the work routine (for example, to automatically turn off at night) if you want. There are four screen modes, as in all of the latest Samsung smartphones: adaptive (with the ability to manually adjust color rendering), photo, video and primary.

The minimum brightness is 0 and the contrast tends to infinity. The maximum brightness in adaptive mode is 369.183 cd / m2. At the same time, the image visibly enters into cold images: there is a lack of red and an overabundance of blue, and the color temperature fluctuates around 8500-9000K with a reference value of 6000K. The color gamut is noticeably wider towards green, which is expected from SuperAMOLED with Diamond PenTile.

In “Photo” mode, the maximum brightness is slightly lower, although the difference is minimal: 354.267 cd / m2. At the same time, the color rendering is much closer to natural: ΔE does not exceed 10, and the color temperature varies from 6500 to 7500K.
