Mute for Ring and Notifications has been removed from the system menus, so it is no longer possible to stop vibrate mode when turning the volume all the way down. Vibrate is ON automatically when you turn the volume to 0. There is a mute option when press/hold the power button, but this option is not accessable to apps that control ring profiles.

I use Quick Profiles to manually select among several profiles and it can no longer access Mute because it is gone from the system menus.

Am I missing something ?
