This phone is not very good and I am using this phone since 2-3 days and no face any huge problems. this phone is works on lollipop version. camera performance is average not very good. sound is pretty good. this phone is easy to use on one hand and very comfortable design. No ambient light sensor. battery life is very good it is 2125(mAh) and works at least one and a half day. ram is 1.5GB it is not good for playing heavy games. look and design is good no too much heavy. my suggestion is if you planning to buy any mobile under 9, 000 so, it is not a good option. I pay for this phone is 8, 700.
