I am facing the touch unresponsive problem since last 14 days. My device touch is unresponsive several times. When it is unresponsive I just off the screen with power button then again press power button/double tap for screen wakeup and then touch works fine. I have tired all the solutions which was given by Nokia customer team and I have visit to Nokia care center also they reinstalled the software but problem still resist. Anyone one facing same issue ?
