I faced a many issues when I try to use this phone to play a high graphics games even doing multi task at the same time and its quickly hitting after use half an hour and not working properly to see and auto hanged to use which is not expacted also. This phone hardware contains are good but I not liked to use this phone I really disappointed to use this phone.
