I believe the Oppo A77S chipset could provide better features. The price in comparison to the features they are providing is not up to the mark. My mother is using a different phone in the same price range and it is providing a better power efficiency of 8000mAh, whereas the Oppo A77S is providing only a 5000mAh battery. This smartphone is designed with a stylish exterior, however, the in-built features of this device are lacking in comparison to the high demands of the generation-z that, they would demand in their smartphones.
I would never like to recommend this Oppo A77S to any of my friends or colleague since it wasn’t worth buying this phone. This smartphone won’t add value to the variety they have been providing in the Oppo A77S.
