Android 4.3.1 : Touchscreen not responding on return from sleep / or after call's end My phone has Android 4.3.1.

Sometimes, when it returns from sleep, or at the end of a phone call, the touchscreen does not respond. I have to press the power button several times to make the touch screen responsive. In the worst case, I have to remove the battery and turn it on again.

What can I do to resolve this issue?

Thank you!
Yes !.... woke my nexus 7 after being in sleep mode all night and it fired up perfectly with no dodgy touch screen issues at all.
Could it be that simple that Chrome browser was causing the problems all along ?

another bonus is using Opera Browser.... after being a die-hard fan of Chrome for many years on my desktop PC, it was a very slight learning curve to master Opera.
It's running so smooth and quick !
