Since july I use mi4 phone and fully thankfull to mi4 coz they give me outstanding phone in affordable price and camera is awesome and speed is very fast and matalic frame gives premium look some people dont have any knowledge that how to use phone correctly and gives fake stupid review . Beware of counterfeit Review, for gaming purpose all big games run smoothly without hang . And infrared senser is good enough I used it to control my Panasonic led tv
