Automatically turn screen on or off during phone calls

I’m having severe trouble with the screen during phone calls. I’m talking about the old fashioned way of using a phone - holding it to your head between ear and mouth.

Expected behavior:

  • The screen is turned off when moving the phone close to the head.
  • The screen is turned on when moving it away from the head.

Actual behavior:

  • The above, but very unreliably.
  • The screen NOT being turned on when moving it away from the head.
  • The screen being turned ON while it’s on the head. Several of my calls have been interrupted, because my ear or cheek must have hit the hang up button.

I haven’t had that problem on my Sony X3 using iode’ 2.1. I have only talked this old school way a couple times but usually use a bluetooth audio interface. I have gravity screen installed (not open source and in aurora store). That app turns off the phone screen when the phone is flat on a table or upside down in your pocket. I usually speak and hear through a bluetooth speaker then and the phone screen goes blank.

Sorry for answering sooo late. Maybe the last update solved this problem ? We did not investigate the issue yet.

No, I’m afraid not. I had started to avoid regular calls anyway, but to mostly used headphones, etc…

As I described earlier already it doesn’t go bad, but around 50% of times in my case.

Just had a call the regular way. The phone screen did blacken when I put it to my ear, but when the call ended I couldn’t easily hang up because the screen wouldn’t go back on. I had to use the power button to achieve that.

Maybe you give “Simple Dialer” a change.
It is configurable to use or disble proximate sensor.

I don’t have a samsung and don’t use iode yet, but i only use this app. i am convinced of it. Use all of the simple tools…
maybe it works for you as well as expected…

Just tried Simple Dialer. It does behave slightly different, but mostly the same.

And I’m afraid deactivating the prox. sensor isn’t really helping my case because my ear/cheek will still touch controls.

Now I started duckduckgoing for the problem in general, not in relation to LineageOS or iode.

It looks like this is a hardware problem in the entire S10 series :sleepy:

That would be pretty unfortunate. The ability to make phone calls is pretty much a main feature for me.

I haven’t found out yet if this can be compensated by adjusting some threshold setting, maybe even before building the phone image.

That’s really bad. F***k…
