@nephros thank you for the toggle button! I just installed it on 4.5.0.24 and it works perfectly and as described in this thread. The warning “while no apps are accessing the camera” makes me wonder what could happen if I do it…
Does anyone knows why this happens? the thing where not all cameras are available at once like xperia 10 ii?
Edit:
Found it as I was looking the source code: Camera | Sailfish OS Documentation
It works just fine also with SFOS 4.6*, but the toggle button icon is gone!
I probably could work around this on my own, but @nephros might want to fix it for all of us? 
Yayaya will get to it eventually! 
I know what to do (not that there’s any useful docs from Jolla…), just have to get around to do it.
But I understand functionally everything is OK, just the icon is empty?
Yep, just the icon… and some more chars. 
OK, the fix is in, put on Chum:Testing, and on it’s way to Chum.
Unfortunately due to unrelated things, packages do not build currently for 4.6 on OBS. So in reality no real fixed package is available at this time.
Once the issues with building are fixed, the package should become available automatically.
Thanks, much appreciated!
