Low-cost smartphone with fast battery charging, stereo sound and NFC-module on board. Among inexpensive "fellow soldiers" the model stands out with support for a 33-watt wired charging of a 5000 mAh battery. Another notable feature of the character of the device is the flat side edges of the case. OPPO A57s 64GB was equipped with an IPS screen with a diagonal size of 6.56 inches and HD + resolution (1612x720 pixels).
The refresh rate of the display is standard - 60 Hz. The chipset in the smartphone is formally gaming (MediaTek Helio G35), but in fact it belongs to the entry level and is unlikely to easily handle resource-intensive applications. The amount of RAM on board the mobile device is 4 GB, and the capacity of the standard data drive is 64 GB. To expand the capacity of internal storage, a hybrid tray for SIM or microSD card is provided. Takes pictures of a smartphone with a 50 + 2 MP dual rear camera, self-portraits are designed to “click” an 8 MP front camera in a teardrop-shaped display cutout. The device identifies the owner by a fingerprint using a fingerprint scanner in the side power button.
