Constant refocussing instead of continuous focus?

On my Moto G the camera seems to refocus every 3-5 seconds even though nothing in the camera view changed.

Perhaps related, sometimes the focus is beeping very frequently (varying between 3 per second to once every 2-3 seconds)

Does the app trigger the refocussing?

Hi, this seems to be the default continuous autofocus behaviour on some devices :/ The app does not trigger the refocussing, it just tells Android to use the focus mode "FOCUS_MODE_CONTINUOUS_PICTURE" (autofocus) instead of "FOCUS_MODE_AUTO" (manual autofocus).

On my device (LG G4) it works like expected: If autofocus is enabled, the camera autofocusses only if the view's changed. If manual focus is active, the camera only focusses on tap.
But on a Moto G (3rd Gen.) I can reproduce your autofocus issues.

I will see what I can do about it ...

Stomehow it seems to work much better with OpenCamera - at least for me. Another thing that works better with OpenCamera is when the flash is turned on/off the preview image brightness adapts almost immediately to this while it takes a while with visor.
