Help LG G8 ThinQ Screen Blacks Out During Calls after update

[jkgraves]

My phone installed an update a couple of days ago. It is running Android 10, Software Version G850UM. Every since just as soon a I dial a phone number and press the phone icon to start the call, the screen blacks out. The only way I can get it to come back on is to press the power button. This seems like it may be a proximity sensor problem, but it does the same thing if I lie it on the desk and call a number. It is very inconvenient to end calls and for calls where you need to dial a number to get to a specific department. I also discovered that as soon as a voicemail begins to play the screen blacks out and I have o press the power button to get it back.

Has anyone else experienced this and found a fix for it? I have powered the phone off and on. I have turned the proximity sensor off and on - although I doubt it is the proximity sensor. I do not see a setting which would control this.

I really need to get this resolved. Any suggestions would be greatly appreciated.

Thank you in advance for any suggestions.

if it was after and update, you could have either a bad install or a bad download. try factory resetting the device and see if that helps.

and p.s. there is no need to start another thread. i alerted the mods to take care of it.

Thanks, but if I do a factory reset, will I not lose my current settings and data saved on the device? Really do not want that to happen.

yes you will lose data....i never have owned an LG device, but can you use this to back things up?

Thank you. Suddenly late yesterday the phone started working correctly. I didn't change anything. Not sure how that happened. But for now it is all right.
