I will say it a new discovery of Xiaomi. The way it has released this smartphone is tremendous. It has all the possible functions in the best possible versions. Let me take anything whether it is about screen or camera or its body or say its processor or take the ram and rom. It has beaten every smartphone not only in its range but also of higher prices. While using I have an awesome feel. Snapping pictures with it was being a professional photographer and I take it granted that it will never hang in any circumstances. The battery of 4000mAh is fairly good and one more thing that I observed very special in it is its fast recognition in fingerprints and face recognition. The back design is quite fabulous. Regarding its speed I must say adreno is showing its power. Overall I think it the best smartphone launched ever.
