After a call the screen is black

Help Fairphone 4

I searched for any solve but I didn’t found anything. The screen i black and I can’t do anything. I tried to just leave it for a few minutes and sometimes it worked after that, but oftens not. I had to put out the battery and start again. I only get the problem after a phone call, doesn’t matter if I made the call or if I recive a call. Now I recall that this was a problem before, when I had an FP2 or Fp3. It was the promixity sensor. But I can’t find it on FP4. I’ve only got my FP4 a few weeks and I’ve read that other had similar problems but not after calling.

I remember I had this during a call. And when it ended, the phone remained black. Proximity sensor is likely to play a role in this, but I’m not sure it’s of any help to know that. I think I managed to reboot the phone by a long press of the power button.

Same here. The screen remained black after a longish call. Only a reboot with a long press would solve this problem.

Also, did these problems happen outdoor?

I agree, this sounds like a proximity sensor issue. The sensor is at the very top of the screen, to the right of the camera, about 22mm from the right-hand side of the screen (as projected past the rounded corner).

Thanks for your answers. Now it seems to be alright, I haven’t had the problem for some time. Maybe the last update fixed it??

I Alis, have exactly the same problem. Have you found a solution ?
Thanks

Yes, it happened mainly outside in bright sunlight.

The FP4 has shown problems with the proximity sensor in the past.
I recommend reporting your problems to official FP Support.

Then it is a known problem. The more people report it to support, the faster we can expect a solution (not a linear scale, though :slight_smile: ). So don’t hesitate and report the problem.

This problem might be related to Proximity sensor goes crazy in sunlight (WhatsApp, Signal, Facebook Messenger, Stock Dialer, WaveUp)

Hi. Not really. It’s better now and only in bright sunlight it takes several seconds to see the screen. I got the screen brightness on auto, maybe that’s why it behaves like that??
