I used this device I think oppo has improved a lot with it's processor it comes with mediatek helio p60 working on 2ghz clock speed I specifically Love the back design of the phone it feels very premium in hand and looks very beautiful. Oppo f9 pro has a good 16mp+ 2mp camera and 25mp front camera the camera performance is good that oppo always maintain in their phones.i think it is a good product around a budget of 20 thousand
