This is OPPO A57 4G. It is different from the A57 5G, and should not be confused as the same phone. This model is powered by a Helio CPU from MediaTek, instead of the Dimensity Chipset used on the 5G model. But from the front, you are getting the same 6.56-inches screen, with 720 x 1612 pixels and there is a dewdrop notch on the front as well.

The hardware department of the OPPO A57 4G includes the MediaTek Helio G35 octa-core CPU clocked at 2.3GHz, along with PowerVR GE8320 GPU. The model has 3GB RAM, paired with a single 64-Gigs of internal storage.

Camera specifications on the A57 4G includes a 13-megapixel primary snapper with f/2.2 aperture, and a secondary 2-megapixel depth with f/2.4, along with a single LED flash, while the notch on the front houses a single 8-megapixel selfie lens.

Interestingly, the phone is based on ColorOS version 12.1 on top of Android 12 OS. There is a side-mounted fingerprint scanner, 5000mAh battery with 33W SUPERVOOC charger, and a slot that can carry dual Nano SIMs with 4G network on both SIMs. All other specs of OPPO’s A57 4G model are contained in the table below.
