My friend recently bought this device from Amazon. Although he's happy with the device but there are several issues with it as follows
Firstly, the phone is not very good looking. The back cover is matte finished and made of plastic which kind of looks cheap.
Secondly, the phone lags sometimes and heats much while charging.
Thirdly, the camera is not very good, as compared to same priced phones like of redmi, xiaomi, letv, etc.
Overall not a very good phone according to me, I would not recommend.
