Z2 screen becomes inactive

[vjuneja]

Almost once in every week, the screen becomes inactive and I have to take out the sim card n restart the phone.
Side buttons and camera work, display also works, phone processor also works but the screen cannot sense any finger touch.

Can anybody suggest any solution to this please?
Thanks!

Nope. I dont have any task killers or battery savers.

Keep us updated.

I have never used any task killers or battery savers.
I also clear the cache regularly.

I still face the same problem of inactive screen.
I am left with no option but to restart the phone by taking out the sim.

Its really annoying when the screen stops sensing the touch.

wipe screen with a cotton based cloth like your white  under shirt  before restarting

Use STAMINA mode to automatically improve battery time when the battery reaches a certain charge level. A function called Extended standby recognizes when your screen is not active and can automatically disable Wi-Fi and cellular data. Most applications then become inactive. Once the screen becomes active again, your device starts to function normally and all disabled functions resume. You can exclude some applications and services from being paused in STAMINA mode.
