Everything around cameras works so much differently per Android version and manufacturer, that I just cannot fix some of the bugs without having a device with the particular issue :/

Not only the around cameras will trigger this error, but also other flashlight apps(like Camera your team developed, Open Flashlight, Search Light, etc. in F-Droid) will cause similar problem. You can use these apps in the Step3 for further testing.

Try downloading one of the popular flashlight apps on the market and then install and try to use this app. Then you should get this problem.

I couldn't reproduce it on my friend's device as well.

Yes, I get this, but Simple Flashlight seems to be closing resources fine. EasyLight breaks Simple Flashlight in my case but if I try to start EasyLight after Simple Flashlight on-off, everything works.
