This project demonstrates the problem with RINGER_MODE_SILENT
Steps to reproduce the problem (including sample code if appropriate).
final AudioManager audioManager = (AudioManager) context.getSystemService(context.AUDIO_SERVICE);
/*
UNEXPECTED Effect.
sets the sytem into "DONT_DISTURB",
which, near setting phone to silent - has many side-effects,
like hiding also notification icons
*/
audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
What happened:
Trying to put the phone into silent mode, so that when a notification arrives - the phone does not ring or vibrate when a voice-call arrives - the phone does not ring or vibrate by setting the ringmode to "android.media.AudioManager.RINGER_MODE_SILENT".
Unexpectedly this puts "DoNotDisturb" on, triggering many side-effects near just silencing the phone.
What you think the correct behavior should be.
- When putting the phone into
RINGER_MODE_SILENT - then the phone should remain silent (not vibrate, not ring)
- when a notification arrives remain silent (not vibrate, not ring)
- when a call arrives AND the DoNotDisturb ode should NOT be switched on.
Is this a security related issue? Yes/No
No
