I think there is a weakness in a31 touch screen. Sometimes when playing games, the phone is heat up, the touch screen is not effective. Means i touch the screen but the phone cannot react instantly. Eg, i am moving my character in games, but the touch screen made my character keep moving and stopping, like stunning. Not sure whether is the phone heat up problem that cause this.
Ps. my tempered glass is not that thick tho lower the sensitivity of touch.
