Screen won't turn on during phone call

2016-07-01, 14:14 PM

Ever since I bought the Moto G4 plus two weeks ago my phone screen won't light up during a call. The screen goes black and unresponsive even when I move the smartphone away from my ear. The only way to get the screen back is if the phone call is terminated by the other caller. There's no way to dial into an automated system cause I can't see the keypad and I always end up leaving a message in everyones voice mail cause I can't hang up the phone call.

 

I always try to press the power button to see if it would turn on and it does nothing until after the call is over. I'm not using any case or screen protector. Is it an issue with the proximity sensor? Would anybody be able to help me with this?

Solved! See the solution

Test in safe mode and see if the problem persists:

 

To reboot into safe mode, tap the power button until you see power off on screen. Then tap and hold power off (on screen) and a new menu will appear to reboot into safe mode.

You checked most of the easy stuff. Can you dial a call and put the phone down on a table, and then just hold your hand over the prox sensor (upper left side of the screen when you are facing it) to see if it goes off and on that way? (Phone can't be on speaker mode, etc.)

 

You can also download an app, like "Proximity Sensor Finder" to test your sensor. 

 

The other thing I would try is testing in Safe Mode to see if this is an app issue. To go into Safe Mode, press the physical power key, then press and hold the pop-up "Power off" key until the Safe Mode instructions pop up.

 

There is at least some chance yours is faulty and needs to be repaired, but I doubt it.

Please do not PM me - if you have issues, search the forums for threads on your topic and post there, or start a new thread. Thanks!

Do you know which app was causing this problem - 

 

I am also experiencing the screen black out / wont stay lit as well as speaker phone volume issues -  

 

I tested it in safe mode like suggested and it works fine... so It has to be one of my apps.

 

Matt - would you mind looking at my phone and see what you would suggest?

Do you have a case or screen protector? Did you try the testing methods or apps matt suggested above?

I am also facing the same issue. Yes i use a silicon case and a tempered glass screen protector. I tried call function in safe mode , and yeah it works well. But how long i hv to switch it into safe mode as it disables all third party applications including some important applications. Please reply with a solution.
