Summary

With the Signal application, when I make a visio with the front camera, it works well. But, when I try to switch with the rear camera, the image for the other person is frozen.
  • The device is unusable

The problem

Steps to reproduce

  • Have a Samsung Galaxy S7 edge
  • Download e-0.8-n-2020041549770
  • Download Signal app
  • Video call with Signal to another person who also has Signal
  • Switching with the rear camera

What is the current behavior? When I switch with the rear camera, I can see my phone's image working, but for the other person, this image is frozen.

What is the expected correct behavior?

The other person should see the image from my rear camera.
