GrapheneOS It is not a data exfiltration toggle, which would require apps having quite a few things taken away for basic enforcement including ability to play audio.
Hm, I see. However, if this permission serves a different purpose, what is that purpose? In my understanding it just serves to secure the use of the app. It's understandable that the app will be able to transmit information via audio, but it's like it's too much.
GrapheneOS You seem to be misunderstanding what it means and think it's a much more narrow concept than it is.
So my mistake, that I thought there were a lot fewer ways to communicate. And there may be various other conditions where programs can do that.
Then don't I have the full ability to isolate the program from everything?
I thought that communication scope, network right, storage scopes and so on were just for that...
I apologize, I just really want to understand
