Oppo f1s giving best features than any other mobile.it has latest processer thus phone is Amazing. I really give best rating oppo to manufacture such a good phone. It has 16 megapixel front camera and 16 megapixel back camera. It has similar function like iPhone 7. Camera result is best. I adviced someone to buy the oppo if he or she is thinking to take or not. It gives best touchscreen. Oppo contains HD voice thus the voice is audible more sharply.my opinion is that about is good .
