I use the phone for review so, in my opinion Oppo has lunched this phone only for the selfi propose because the processor and the battery is so poor, the front selfi camera is good but the rear camera doesn’t perform well if we talking about price it is very high 14018 rupee.
I suggest you to don’t buy this phone fir the selfi there are other phones in the market which give much more feature in lower price
