Help Screen shuts off during calls

[nightowl66]

When I am on the phone the screen shuts off, I can't get it to come back on unless I hit the power button which is set to end the call.
Any suggestions?

I think you should try replacing your battery and see how that works. Whats happening is; your battery loses power abruptly when you access applications that require more power.

The battery is not replaceable, the phone is only a few months old. it is not a battery problem

Double tap the screen in portrait position?

See if it happens in Safe Mode. Also you can run the phone diagnostics to see if the proximity sensor is working correctly.

Don't use tue power button to end call. Screen is supposed to shut off so your face doesn't press anything.

It may be a KitKat issue. My fiance's, sister in law's, and my Nexus 5 do this and my father in law's HTC One does it.

Highly aggravating as my phone doesn't end a call when hitting the power button.

Edit : Yes, the phone has a sensor that shuts the screen off when it gets close to your face during a call but going straight black even when pulled away is a glitch of some sort.
