Smartphone manufacturers like to release their budget carriers in two variants, which differ, for example, in the connectivity offered. This change also entails replacing the chip with a cheaper one to further reduce the price or offer some additional options without increasing the cost. How is the Oppo A57 4G?
There are several differences between the Oppo A57 5G and 4G
Of course, the biggest change concerns the system, because instead of the Dimensity 810 we have the Helio G35 in the 3/64 GB memory configuration, which is less than in the 5G variant. However, there is an option to expand the RAM up to 4GB, as well as a microSD card slot up to 1TB. By losing 5G connectivity, the Oppo A57 gained a 5000 mAh battery, which we can charge with no more than 10 W and 33 W, which is a really nice change.
Unfortunately, the new variant does not bring only improvements, because the manufacturer has reduced the refresh rate of the 6.56-inch LCD screen from 90 Hz to 60 Hz. HD + resolution remained unchanged. In addition, we have an 8 Mpix selfie camera, a double configuration on the back (13 Mpix + 2 Mpix), a 3.5 mm headphone jack and IP54 protection class.
There are no big differences in appearance, these are limited to small changes within the camera island. The smartphone works under Android 12 with the ColorOS 12.1 overlay.
