that is exactly what i was looking for, thank you.

Though now i dont feel comfortable giving it so much control over my phone. Though since code is open source I hope someone has looked it through. I tried taking a look myself but i wouldnt know what to look for.

It also seems to be also unmaintained or it just doesnt need updates, as last change to github was 4 years ago. Too bad there doesnt seem to be almost any other programs like that, only other i found was something called safe-dot which is equally old. Based on issues listed in github page it might not work 100% reliably. It seemed to work when i tested it, but according to the issues it might not work if system itself is using something which kind of defeats the purpose.

I also noticed that for some reason it didnt appear on rethink's application list so i couldnt see what it was doing with network. According to system it used 8kb worth data in backround even though it doesnt seem to have anything that should require internet, unless pushnotifications do that, but still that seemed a bit odd for program that shouldnt use internet.

Looks like it's no longer on the Play Store, but I did find SafeDot on F-Droid.

i might do that too, but turning them on and off constantly would be such a bother. Also it would be annoying to forget microphone when someone calls or you call to someone. I wish i could just install grapheneos or something, but fairphone doesnt seem to be supported for it and at this point i wouldnt want to risk losing my data if something breaks.
