MediaVolume appMediaVolume is System tool that is open source under the GPL-3.0-only license.
MediaVolume provides Quicksettings Tiles for media volume.
The app doesn't have any UI, only 7 tiles will be added: Media Mute, Media Min, Media 1/3, Media Medium, Media 2/3, Media Max and Media Panel, which can be added directly from the notification drawer switch panel. As a feedback, clicking on a tile will display the system volume panel.
Tip: Individual tiles can also be toggled off/restored, please take them as you need them. The reason for this is unknown and can be solved by restarting Android after editing the tile layout.
