Bug description

My device has no selfie camera due to security policies.

Competitor apps and the Camera app itself work fine, but Signal does not, resulting in using a different app when I need to do a video call.

Taking pictures to send in the chat with the Singal app works, but when I get into a video call my side just shows as black. Tapping on the swap button to change from selfie (assuming it is the default camera when starting a video call) to rear camera changes nothing.

The app should check if the selfie camera (and vice versa) is available and either show a message for the user to switch, or automatically switch the the other functioning camera.

I'm sure this bug/issue targets a very small number of users, but I believe it should definitely be considered.
