Can see black zoom default UI, when user dismiss participants screen

If an iOS user has a secondary screen open when a third user leaves a conference, they initially see a black screen.

Which iOS Client SDK version?

To Reproduce
Steps to reproduce the behavior:

  1. User A, B, C: Log in on an iOS device.
  2. Start a call between users A and B.
  3. Either user: Invite User C to the call.
  4. User C: Join the call. (Whenever 3 users in a meeting, using switchToVideoWall() to change the display mode to the grid. So all the users in these steps will change to grid view)
  5. User A: Open up a secondary screen (Participants screen).
  6. User C: Leave the call.
  7. User A: Close the secondary screen.
    RESULT: User A sees a black screen, with no meeting controls.


  • iPhone 10S Max, iOS 13.5.1
  • iPad Pro 9.7”, iOS 13.5.1

Additional Note

  • Once User A interacts with the screen, the video stream comes back.
