I want to programmatically (from C++) change the ringing volume of the device. If I have understood the profiles correctly, the device seems to have "mute", "silent", and ringing with separate volume control. How can I control these, I can't quite locate the API.
I'd also like to change the aeroplane mode if possible.
Use case: automatically setting the device to silent during night or during scheduled meetings. Automating aeuroplane mode can be also useful to preserve battery during night if you're not interested in calls.
