The "Can't connect to the camera" error of cyanogenmod persists.
Earlier I was using Cyanogenmod 11 and faced the same issue but there was a quick fix available - Restart_camera.apk
That ofcourse was meant for KitKat and doesn't work for 5.1.1.

I have to reboot my device several times to use the camera.
Is there any fix for this?

Thanks and Regards
