Sound
The built-in audio system is probably the most commendable feature of the A9 2020. Unlike many other gadgets, this smartphone is equipped with a dual speaker and supports Dolby Atmos technology . Recall that 2 years after the release of Dolby Atmos development for cinemas, Dolby Labs also adapted it for PCs, game consoles and mobile phones. The mobile technology works using sound processing algorithms that convert Atmos object metadata into a 360° binaural output signal using two conventional speakers. This method is an improvement on the previous Dolby Headphone technology, which allows many channels of sound to be converted into a virtual environment.

One speaker is located on the bottom edge (to the right of the USB Type C port), the other uses the sound membrane located above the front camera. Two such speakers provide, firstly, quite loud, and secondly, really high-quality sound , with a pronounced stereo effect . By the way, the A9 2020 sounds so loud that it can, for example, be used as a speaker when driving in a car.

Also worth noting is the standard 3.5mm headphone jack located on the bottom. The included headset has a control button that allows you to start and stop playback of a multimedia file.

Software
Like most other manufacturers, OPPO does not use “pure” Android in its devices, but its own adapted configuration paired with the proprietary ColorOS 6.1 shell . This shell offers individual application settings to optimize gaming processes and reduce power consumption, synchronization of the smartphone with the OPPO Cloud cloud storage and other turkey number data services. There is also an improved intelligent assistant that provides quick access to selected contacts and applications, weather forecast, pedometer, photo albums, etc.

Camera system
OPPO A9 2020 has as many as five cameras — one front and 4 photomodules on the rear panel. The front one is distinguished by a 16 MP matrix, an F2.0 aperture and AI software with a beautification function . The latter automatically determines age and smoothes different skin tones depending on gender, and also adjusts pictures in accordance with modern beauty trends. well, but in low light it blurs the image a little. True, there is a flash here, which uses the screen as a flash — when the shutter is released, it glows white at maximum brightness.

The main camera, located on the back panel, consists of 4 photomodules : the main one, located in the center, has a 48 MP sensor and an f/1.8 aperture. Above it, the developers placed an ultra-wide 119° lens for panoramic shots with an 8 MP matrix and an f/2.25 aperture. Two more are equipped with a 2 MP photosensor and an f/2.4 aperture. These two modules, one of which is a depth sensor (located on the side under the flash), i.e. a depth sensor, are auxiliary and are designed to create artistic portrait effects.
