Yeah, sounds strange, I know. I'm using DailyRoads Voyager as a dashcam/blackbox when driving, and one issue is that it stutters occasionally when it's muted (using an in-app setting). But if you leave the sound on it works fine. So I'm wondering if there's a way to mute the microphone whilst using the app (I'm a spy you see, so my in-car conversations often contain highly sensitive material). The only thing I can find is some of these apps that deny certain permissions. Can't find an app that could do it. Anyone got any ideas?
