I cant change the lens I use when I quicklaunch from the lockscreen on my s10+. It just buzzes a little and then does nothing. Really anniying when Im trying to capture a cool moment.
I have the same issue and haven't figured out a work around , super annoying and defeats the whole purpose of being able to quick launch camera. Didn't have the problem on my note 9...
Same here with my S10, waiting for bug fixing, didn't happen with my S8 Plus!
