'Camera and flashlight used by other app and cannot be used' is the error that I get when I open my camera or try to turn on the flash light..
I have factory resetted my phone after trying the safe mode and deleting app methods.. but still it says it is occupied by some other app..
Not sure what to do now extremely frustrated.. need help
Go to permission manager in settings >Apps (applications) and see which apps have access to camera. Remove the apps you don't want having full access to camera all the time. If all fail, you can clear data and cache on the camera app.
