***This app mutes media only, on some devices it won't disable the camera's shutter sound.
Simple Media Muter is a one-click app to mute your media stream (like songs or game sounds). It is not a widget, which means that uses no resources at all! Simply put a link to it on your homescreen and you can mute and unmute your media with one click.
It is not possible to change the icon after muting, as it is not a widget.
