Deltachat-android: Camera (live view) turned off (black screen) after rotating device

[gerryfrancis]

• Operating System (Linux/Mac/Windows/iOS/Android):
  Android 10 on Fairphone FP2 (Lineage OS 17.1 build QQ3A.200705.002 from 2020-08-07).

• Delta Chat Version:
  1.12.2.

• Expected behavior:
  When live view of the camera is turned on (to take a photo), rotating the device adapts the view (from portrait to landscape or vice-versa).

• Actual behavior:
  When live view of the camera is turned on (to take a photo), rotating the device turns the camera off and the screen is black. (However, the navigation bar on the right is visible works.)

• Steps to reproduce the problem:
  -- Start a chat.
  -- Tap the camera icon to activate the camera.
  -- Rotate the device. (Result: The camera turns black.)

• Screenshots:
  N/A.

• Logs:
  deltachat.txt

• Remarks:
  -- Rotation of screen is configured and works.
  -- Changing the camera (from front to back or vice-versa) brings the view back. For now, a possible workaround is to change the camera twice.

i have the effect every 2nd try or so - and i have the same bug also when rotating back to portrait (also not always, but often)
