Hi Doudera,
Thank you for reporting this issue. It is working as intended. This is because the state of CameraControl follows Camera. Once the Camera is closed, all settings will be restored, just like the settings of the focus area and zoom level. The app can restore the torch state by resetting torch at the time of activity onResume.

Hello,
thank you for the fast reply. The behaviour is unexpected to me because if you have the same code as before and just add logging like this:
camera = cameraProvider.bindToLifecycle(
this, cameraSelector, preview, imageCapture, imageAnalyzer)
.apply {
Log.d(TAG, "Enabling torch after binding") // <-- called everytime it returns to Activity so next statement should be applied
cameraControl.enableTorch(true)
}
The log is always called even when returning to Activity so I suppose it should be applied. Why it is not applied when it is called?
Unfortunately, I cannot make it work even with your hint. I tried to add camera?.cameraControl?.enableTorch(true) to onResume() but without any effect. Can you please describe more how to reset torch state onResume().
As you said the same happens with setZoomRatio() etc.
Thank you, Martin

Hi Doudera, Thank you for the detail description. It sounds like some problem in the code. I will investigate it more.
Description
The Fragment should maintain the Runnable so it can be removed later.
