In addition, the memory and storage of this model have also changed. The 4G version has only 3GB of RAM and 64GB of storage space and supports up to 4GB of RAM expansion and up to 1TB of storage expansion.
At first glance, the OPPO A57 4G looks the same as the 5G version, but after careful inspection, you will find that the design of the rear lens part is slightly different. In addition, the 4G version also adopts the OPPO Glow design.
The OPPO A57 4G uses a rear dual camera consisting of a side fingerprint, 13MP main camera + 2MP depth sensor, an 8MP camera on the front, USB-C, 3.5mm headphone jack, IP54 rating and Dirac 3.0 certification, ColorOS 12.1 based on Android 12 is pre-installed, and it is available in two colors.
