When I actually used one plus 2, I was not very satisfied with the camera and cuttings behind. It was not as good as I thought before buying that phone, as well as the touch id passcode too. And I was very disapointed for all that. but, 6gb ram, 3000mah of battery, gorilla glass 4, 16 mp of excellent rear camera and 8mp of front camera with a 64gb of internal storage changed my thinking of one plus 3 in category of one plus phones. this has settled a very high level in my mind about one plus phones. and the super fast fingerprint sensor to, with tap unlock. The designed of one plus 3 is also as excellent as its performance.
its speakers are also very very good and network coverage too ive used it with my airtel 4g sim, it works excellent.
