I faced the same problem on about 10 new Samsung devices running Android 14

I have the same issue, and I have further information:
When I compile Element's code with targetSdk set to 33, the issue does not happen. Probably Google changed something between targetSdk 33 and targetSdk 34, IDK what.

I can confirm this on a Pixel 6a using GrapheneOS.

This should be fixed urgently as it keeps me from doing hands-off calls.

@bmarty Hello. Is there any chance that this bug can be patched? Those who that don't know how to downgrade or use GitHub are basically cant use this app calls. I see there are updates for Element X but not for this client.

I can confirm this is still the case on 1.6.22 [40106222] (G-9a4602bf).

Tested on the OnePlus 7T Pro (A14).

Calls are nearly unusable. Including the fix from PR in the next release would be highly appreciated.
