My friend bought this phone from a local store 1 month back. we all know oppo and vivo do so extensive outdoor marketing for the promotions, but we never understand as customers that OPPO will charge the money used for marketing from customers only. Let me tell you the specifications of this phone first.
Oppa A57 has Snapdragon 435 chipset, 3GB ram and 13 MP camera, this same specification is there in Redmi 4 that costs 9000rupees, can you believe it, you guys. OPPA is basically charging you guys 6000 more for the same specification phone and the build quality is no where compared to other phones in market. They have only one selling point that is selfie camera nothing more. The UI is good, comes with android 6.0 marshmallow. Other than selfie it cant do anything that makes it worth 15, 000. Only 2 things you get to see in this phone that is Design and UI that is good nothing else.
Dont buy this phone people its just a waste of money and later on youll regret it.
Thanks you.
