I tried to use the camera2 example in landscape view. (#SupportedOrientations: landscape)
The preview image has been stretched and enlarged, but the photo is good. (see attachment)
I tried the following:

I'm using Erel's example for Camera2: https://www.b4x.com/android/forum/threads/camera2-still-images-and-videos.83920/
I made only one change: #SupportedOrientations: unspecified

My App using Camera2 occasionally crashes by going into Activity_Pause.
I have created a watchdog attached, but I cannot get the activity to restart or resume.
I have included MANAGE_OVERLAY_PERMISSION and also added it to the manifest, that part is working.
The timer is also working as it is...

Strange situation with Camera2 usage for the video recording:
1) Debug version works fully OK: preview is restarted OK after each file saving.
2) But Release compilation shows the preview only for the very first time, and later the preview is not visible, but capturing is anyway OK.
I'm writing a timelapse app using a foreground service to keep the process running and all is fine until the display "goes to sleep".
When the Main Activity is re-awakened by a CallSubDelayed from my foreground service, there is no response from the line "Wait For Camera_SurfaceReady" in...
