I have been using it since 6 months. Oneplus 2 is a smartphone coming with 4GB of Ram which is a plus point of it. Initially it having some issues regarding fingerprint sensor and battery life but after the update of oxgyen 3.0 its quite easy to use. Its fingerprint sensor works faster even than iPhone.
Its camera quality is just superb also having laser focus which help us to focus on moving objects also. I liked oneplus 2 and recommend you to go for it
