Hello, I just bought a Lumia 820 and turned to Windows Phone. But I don't know how to completely mute my phone. I tried to use the "mute" button of the volume control bar but it doesn't made every sound mute. Some applications still make sounds. I tried to turn the volume to 0 but it's to complex. Is there a way or an application that can completely mute my phone by one or two click?
Sorry for my poor English.
