For the manufacture of screen uses In-Cell technology (option One Glass Solution), which prevents the additional air layer. It is believed that in addition to a good anti-reflective properties, thus provides better contrast and color reproduction. Wide viewing angles are accompanied by typical contrast ratio (500 1:1) and brightness of 480 nits.

to Adjust the brightness either manually or automatically, activating the switch “auto adjust brightness”. For the power saving mode dimming towhich can be activated for third-party applications include manual and scheduled. In the tab “vision Care” the intensity of the blue filter (“Color temperature of the screen”), proposed to be inserted in a specific time is selected in the range of “cold-warm”.

Of its eight cores Kryo 260, is made subject to the design standards of 11 nm, four (Gold, based on ARM Cortex-A73, up to 2 GHz) are responsible for the performance, and the remaining Quartet (Silver, a derivative of the ARM Cortex-A53, up to 1.8 GHz) is responsible for the efficiency. Graphics operations takes over the accelerator Adreno 610 with support for Vulcan 1.1, while increasing energy efficiency by 20%. The architecture also provides twice more powerful than its predecessor, the signal processor Hexagon 686 and a relatively simple image processor 165 Spectra. The integrated X12 LTE modem is designed to provide download speed up to 600 Mbps, and transmission up to 150 Mbit/S. in addition, support wireless communication, satellite navigation and quick charge Quick Charge 3.0. The basic configuration of the Oppo A52 complement the 4 GB of RAM LPDDR4x.

Built-in repository on the basis of the UFS 2.1 with a size of 64 GB can be easily expanded with memory cards microSD/HC/XC up to 256 GB of which is allocated a separate place. That is why it does not prevent the simultaneous installation of two nanoSIM-cards. Support USB OTG to connect the Oppo A52 flash drives, including those with SMI controller (with USB Type A and USB Type-C connectors — Dual USB). The volume of the connected external drive can reach 2 TB (support NTFS formatting). Previously in the settings, you activate the OTG mode, which shuts off automatically after 10 minutes of inactivity.

For the cellular 4G version of the Russian ranges of the LTE-FDD (b3, b7 and b20), as well as LTE-TDD (b38). Of wireless communications it is also worth noting wifi 5 a/b/g/n/ac (2.4 GHz + 5 GHz), Bluetooth 5.0 and NFC.

the Interface will be useful for NFC contactless payments (Google Pay), content sharing and easy connection to the appropriate accessories. And here in a duet with the application “Transport card of Moscow” it will help to know the balance of the “Troika”.

review of the Oppo A52: autonomy

In Oppo A52 installed non-removable lithium-polymer battery high-capacity 5,000 mAh. So for almost any reasonable usage scenario of the smartphone stored energy, certainly enough for a whole day. To quickly fill the battery “under the neck” is a 18-watt adapter OP92KAEH (5 V/2 A, 9 V/2 A) compatible with the specification Quick Charge 3.0. With its task it copes in about two hours. Besides, in just 45 minutes the capacity is filled approximately halfway. A fully charged battery to deliver up to 34 hours of telephone conversations, up to 7 hours of video viewing and up to 50 hours of music audio. Playback test videos in MP4 format (hardware decoding) at full brightness every hour reduces the battery charge is approximately 7.5% (option intelligent power saving enabled).

In the section “the Battery” (“Battery”) is to select the power-saving settings, to determine the function of high productivity, and to use optimization hints.

review of the Oppo A52: the features of the software

Oppo A52 Smartphone running the Android operating system 10, which interface replaces a proprietary shell ColorOS 7.1. The developers pay attention to the comfort mode dimming (“dark” mode), which is activated even with quick switches and reduces overall battery consumption.

the notification Center in this launcher combined with quick switches, where is the slider to adjust the brightness, accessed using swipe from the top of the screen.

Card running apps are listed in a single row with the possibility of horizontal scrolling. One program is removed from memory with a swipe of her card up. But for simultaneous closing of all applications use the icon “Remove” at the bottom of the screen. To display total and available memory, withshould activate the corresponding option in the “advanced settings” in the “recent task Manager”. On the tab “home screen Mode”, in addition to simplified, provides a standard mode (all program shortcuts are assembled on the work tables) mode and “box” with a separate menu (screen) applications. In this section — “home screen Wallpaper” is proposed to define a style for app icons.

On the tab “navigation Buttons” selects the method of control — through bilateral swipe gestures or virtual buttons. In this section, “Convenience” are collected and other tools that facilitate administration. Thus, the “Convenient button” that offers smartphone control with gestures or via a special menu. In turn, the side of the smart bar, you can set the transparency and position, designed for quick access to tools and selected applications, as well as to switch to the split screen mode.

As already noted, the fingerprint sensor combined with the power button/lock. With this arrangement, the platform scanning the advantage is given to the thumb of the right hand thumb or the left. At the same time, to unlock off screen, you can choose a light touch or a strong touch.

the Option “Turn on screen when picked up” is recommended for face recognition using the front camera, the performance of which did not disappoint even in low-light conditions.

review of the Oppo A52: buy, insights

Among the main feature of the Oppo A52 can be called good battery life, which is very high capacity built-in battery with support for fast charging, well and good efficiency of all the hardware, of course. In addition, it is worth noting the sound quality associated with the Dirac technology 2.0 and stereo speakers that have smartphones in the medium price range, generally speaking, uncommon. Among the key features should distinguish a good LTPS IPS screen with a narrow frame, photo modules with the AI functions, availability of NFC interface and the 5-GHz band Wi-Fi, separate slot for memory card, also has a fingerprint scanner, combined with the power button/lock.

the disadvantages of the smartphone include soiled plastic case and very modest, by today’s standards, the performance of the CPU.

In the official online store Oppo at the time of testing for model A52 asked for 17 990 rubles. For the same money (17 990 rubles) large retail chains can be purchased, for example, at 6.67-inch Xiaomi Redmi Note 9S in the same memory configuration (4GB/64GB), who in April scored in the top five most efficient models in the medium price segment. This device, compared to Oppo A52, was not only “rapid-fire” processor, but more advanced cameras, including 48 megapixel sensor in the rear of the photo module. Fingerprint scanners are both contenders are built into the power button/lock, and battery capacity and power quick chargers they have, perhaps, the parity. However, unlike his opponent, Oppo A52 boasts stereo sound built-in speaker.
