I believe camera-ui2 was developed by nicolai.

Since the problem is with fcam, which is most definitely not being maintained, it's not reasonable to expect camera-ui2 to re-calibrate itself to nonstandard drivers which may or may not be present in the phone.

Is there an app that will reassign opening the lens cover to start another program, for example fcam? That way fast camera access would be possible, & it wouldn't be a problem if you forgot to use fcam if it were installed instead of camera-ui2.
