My father was using this phone for last 3 months it is working good, the user interface is quite impressive, the finger print scanner is working good, memory management of this phone is good, marshmallow is working smoothly for this processor, there is no problem of hang for this phone due to 3gb ram, it supports big games, only problem with this phone is it heats up during charging. but the battery is working quite good. if we speak about the camera this is the best of all phones at its rate, but during the usage of camera phone heats up. internal storage is also quite good.
