The A-series in the model range of Samsung smartphones is considered pre-top. On board her senior sample from the 2018 line of devices, it was decided to "run in" a quartet of rear cameras lined up on the "sirloin" part of the device body in a neat row.

The Samsung Galaxy A9 2018 has a 24 MP image sensor with high-power optics f/1.7 assigned to the role of the leading photomodule. In close proximity to it are an 8 MP wide-angle camera with an objective f/2.4 and a 10 MP TV speaker with a lens of a similar aperture. Finally, the fourth in the row was an auxiliary 5 MP photosensor to determine the depth of field of the frame. Frankly speaking, the "quadriga" of cameras takes its toll on quantity, not quality — the final result is obtained at the level of ordinary mid-low-cost employees.

The front panel of the gadget is covered with rounded glass with an oleophobic coating. Below it is a 6.3-inch screen on a Super AMOLED matrix with a resolution of 2220 x 1080 pixels. And no "bangs" — a conversational speaker paired with a front-facing "eye" of 24 MP cameras are located on the upper frame. As usual, the screen impresses with the depth of black colour and supports a constant time display mode along with notification icons (Always On Display). But when deviating from standard viewing angles, the picture on it turns slightly green.

The hardware base of the device is based on a well-proven mid-range Snapdragon 660 chip, coupled with 6 or 8 GB of RAM. In the AnTuTu performance test, "iron" scores about 138K points, which is an "above average" result. In fact, Samsung Galaxy A9 2018 handles with the same success both with everyday tasks and with the lion's share of modern games, giving out consistently high fps without sagging frame rate in long sessions.

With the memory of the model, everything is on top — not every player in the market of modern smartphones can offer a 128 GB configuration from the start. Moreover, in the arsenal of the model there is a triple tray for two SIM cards and a microSD drive (up to 512 GB). Without recharging, the gadget keeps "afloat" for the standard 5-6 hours of active screen time. However, Samsung Galaxy A9 2018 is already a good option for purchase, if you want to get a decent device from a well-known brand without overpaying for flagship "stuff".

Each generation of Xiaomi's Mi Mix series smartphones is recognizable in its own way. The first-born in the line was one of the founders of the frameless devices genre. The "2" and "2s" generations have become charged flagships with a remarkable appearance. And what interesting things did the third device bring? Let's figure it out.

The smartphone is made in the undeservedly forgotten slider form factor, which has been given a new round of development. A retractable block hides a conversational speaker and two "eyes" of a selfie camera — a 24 MP host and a 2 MP auxiliary for blurring the background during portrait photography. According to the manufacturer's assurances, the life of the slider on the magnetic mechanism is over 300K actuations.

It was decided to resort to this format of the device in order to get rid of the annoying "monobrow". As a result, the front panel of the gadget is 93.4% at the disposal of an AMOLED display of gigantic dimensions (6.39" diagonally). Its proportions are 19.5:9, and the resolution is 2340 x 1080 pixels. The minimum frame is present only on the lower face, along the other fronts the screen comes close to the ends of the device body.

In terms of performance, we see a truly top-end device with Pro-level hardware. The flagship Snapdragon 845 processor in tandem with 6/128 GB of RAM does not know the tasks that it cannot cope with. That's just the memory volumes of the smartphone are not subject to expansion. The photographic side of the issue Xiaomi Mi Mix 3 is one of the best cameras in the class of mobile gadgets (at the time of the announcement). According to the DxOMark rating, the rear camera of the model is located on the same level as that of the Samsung Galaxy Note9 128 GB / 6 GB Price from £230.00 up to £290.00 . Only camera phones are higher in the rating than her Apple iPhone Xs Max 64 GB Price from £1,759.20 up to £1,919.20  and Huawei P20 Pro 64 GB Price from £125.00 up to £165.00 .

A set of rear cameras combines two 12 MP photographic sensors (a regular and a TV camera with a double zoom). The assets of the main module have a 4-axis image stabilization system, Dual Pixel autofocus, as well as artificial intelligence that recognizes the scene and objects in the frame. In addition, the smartphone has learned to take high-quality night shots. The crown of the overall positive picture about the device is the support of fast and wireless charging technologies for a 3200 mAh battery. Well, the smartphone is cheaper than peers similar in hardware, which goes exclusively for the future.

The "finished" version of the sixth generation to mind The so-called "flagship killer" is traditionally indicated by the letter T in the name. The model has two cardinal innovations: a reduced "monobrow" of a teardrop shape and a fingerprint scanner directly in the screen.

Along with the fact that the fingerprint sensor moved from the back of the glass case to the display, it significantly increased the speed of fingerprint recognition — the manufacturer of the mobile gadget calls the sensor one of the fastest on the modern market (0.34 s). In fact, it reacts to touch really in the blink of an eye, allowing you to unlock your smartphone without the slightest hesitation. In contrast to the fingerprint scanner, a face recognition system has been installed, an integral element of which is a 16 MP selfie camera.

The OnePlus 6T display occupies about 86% of the front panel area. It itself is based on an Optical AMOLED matrix with a diagonal of 6.41" and a resolution of 2340 x 1080 pixels. The colour rendering of the screen adapts flexibly to certain user preferences in the settings. Also, the smartphone traditionally has no problems with performance — the combination of the flagship Snapdragon 845 chip, 6 GB of RAM and Adreno 630 graphics cheerfully turns over everything that comes to hand.

"In the database" the model is equipped with an internal storage of 128 GB. This figure will have to be satisfied, since there is no memory expansion slot in the arsenal of the device. In addition, although the device is made in the "glass sandwich" form factor, it does not support wireless charging. However, by wire, the battery with a capacity of 3700 mAh replenishes the energy reserves in the tanks in a matter of minutes. The reason for this is the high-speed charging of Dash Charge.

The photographic side of the issue of the OnePlus 6T is represented by a dual rear camera of 16 + 20 MP. Each of the modules has got f/1.7 high-power optics at its disposal, and the main "eye" is additionally armed with a nimble Dual Pixel autofocus and an optical stub. The new "chips" of the camera are the "Studio light" function and the night mode of photographing. Videos are written to a smartphone in maximum 4K resolution (3840x2160 pixels) with a frequency of 60 fps. The cherry on the cake is the friendly interface of the proprietary Oxygen OS shell, under which the device works hard. It is rolled on top of the freshest Android 9 system at the time of the announcement and has a lot of remarkable "buns" like gesture control.

Pixel of the third generation in XL format has retained the features of its predecessor (Google Pixel 2 XL 64 GB ), along with which he got an enlarged 6.3-inch diagonal display. Fortunately, the screen has lost its childhood sores (inversion of colours and pixel burnout during prolonged display of a static image), but it has grown a very large "bang". But about everything in order.

The substrate for the display was an OLED matrix with an aspect ratio of 18.5:9, the image on which is displayed in a maximum resolution of 2960x1440 pixels. The device's screen features include support for HDR and Always On Display technologies, and the latter demonstrates not only the time, date and notifications, but also the name of the audio track being played when listening to music. An important feature of the display is the function of enhancing colour saturation with an extension of the colour coverage of the "triangle" sRGB by about 10%. Gorilla Glass 5 protective glass is installed on top of the screen.

The assembly of the third "Googlophone" is set up at the production facilities of HTC. The Taiwanese brand's smartphones had another interesting "trick" — sensitive side faces. They respond to the force of compression by performing a predefined action (for example, calling Google Assistant).

"Under the hood" Google Pixel 3 XL has a high-performance bundle of the 845th "dragon", Adreno 630 graphics and 4 GB of RAM. The amount of "RAM", by the standards of other flagships, is not enough here, but you need to make a discount on stock Android, and always the current version — software updates from the Corporation of Good "arrive" on Pixel among the first. Having a significant reserve of power for the future, the smartphone has no problems with performance, including when working in "heavy" applications.

Keeping true to tradition, the device again uses a single module of the main camera with a resolution of 12.2 MP. But what! Thanks to him, the model occupies a leading position in the leading ratings of mobile cameras. The main photo module has an optical image stabilization system and a smart autofocus Dual Pixel PDAF. The camera also uses the principles of machine learning to get the best possible result. Even more interesting is the situation with the front—facing camera — it looks at the outside world in two "eyes" with different focal lengths (28 mm and 19 mm, respectively). The model is also supported by IP68 protection, fast charging of a 3430 mAh battery and the provision of unlimited storage in the cloud for photographs, which in light of the lack of a memory expansion slot becomes particularly relevant.

The bet on "pumping" the photographic capabilities of mobile device cameras has become one of the priority tasks set for the "sharks" of modern smartphone construction. The Chinese company Huawei, whose phones shoot the best, succeeded in this matter.

A striking example of an advanced camera phone is the novelty of the fall 2018 season — Huawei Mate 20 Pro. The device received a triple main camera unit, built on the basis of a 40 MP master module (28mm f/1.8), 8 MP telecaster (80mm f/2.4) and 20 MP ultrashire (16mm f/2.2). The optics for each of the modules were created under the wing of the renowned photographic brand Leica. Of course, there was also an artificial intelligence system, which is responsible for automatic recognition of the scene and adaptation of the shooting parameters to it. The dual neural computing module is an integral part of the Kirin 980 CPU, which has become the "first swallow", made according to the 7-nm process technology.

Artificial intelligence deals not only with the issues of photographing, but also helps the smartphone to stay fast regardless of the tasks shouldered. For example, in games, the GPU Turbo 2.0 hardware and software optimization technology will come in handy — the fps value remains consistently high, despite the fact that the gadget's battery charge does not "fly into the pipe", but will be used up as with normal screen reading. The smartphone got 6 GB of memory, as for RAM, and 128 GB, if we are talking about the capacity of the built-in drive. Expansion of the capacity of the regular storage is possible due to flash drives of the new ND Card format.

The model has a number of other notable highlights. Take, for example, a gradient glass backdrop. Firstly, it really creates a "wow" effect, and secondly, through the glass, the smartphone can be charged "through the air" and share the accumulated energy with other devices using the principles of wireless charging technology. When connected to an outlet in the traditional wired way, Huawei Mate 20 Pro charges from 0 to 70% in just half an hour. And the smartphone also has a huge high-resolution OLED screen (3120x1440 pixels) with a built-in fingerprint sensor, high-quality stereo speakers, a full range of communications (including NFC chip), as well as dust and water protection of the case according to the IP68 standard. The laurels of one of the most technologically savvy smartphones of the current era went to the device for good reason.
