If i cover my light sensor, that auto adjusts the brightness of my phone, the whole screen goes black

### Steps to reproduce

If i am in a middle of a call (voice or video) and I cover the front sensor that ig receives light and is responsible for auto adjusting the phone brightness, so that it doesnt receive any light, the whole screen goes black. Nothing helps, even if i click the power button. Only If i uncover the sensor the screen lights back up. It may have something to do that Element requires some proof, that someone is in front of the phone or i don't know.

### Outcome

If i cover the sensor nothing should happen. I think it is not phone/hardware related, since with other messaging apps, like facebook messenger, nothing happens if i cover my light sensor, but here the screen goes black.
