We already mentioned that the A57s and A57e are similar smartphones. Well, the Oppo A57e is basically the A57s having a 13MP primary camera with no stereo speakers or NFC onboard. It also comes with Bluetooth 5.2 instead of 5.3.
You can also call the Oppo A57e a version
of A57 4G with Bluetooth 5.2 and a single memory option - 4GB RAM and 64GB
storage. The Oppo A57e comes in Green and Black colors and is available for
purchase in India through Flipkart for INR 13,999 (US$ 175/€ 175). It's unclear why
Oppo launched the A57e in India when the A57 4G is also sold at the same price through
its official website (even lower on Amazon.in) with the same amount of RAM and
storage.
