The sound is decaying the clearity of the sound but the video 1080p is good enough.when it comes the operation performs in the menu is not good good whenever I put a launcher the phone lags. the software in the OS is not obey the mx player.even when we play the high graphics games the phone lags.the style compare to the other it is not good.the gorilla glass is the only one positive thing in this mobile if anyone buy this phone they will return the phone next day
thank you
