A free app for Android, by Nik Satyr.
The best volume control app for Android! If you’re looking for a simple way to increase and decrease the volume of your music and video files, then Volume Control: Notification & Overlay Widget is exactly what you need!
There are two ways to use this app. You can use it as a notification with audio controls or an overlay widget that will appear on top of all your apps.
Notification
If you want to listen to music or watch a video, just open the app and press the “Show notifications” button. If you want to adjust the volume of the notification, just tap the volume up or down button. If you want to mute the notification, just tap the “Mute” button.
You can also adjust the volume of all your media files from your phone’s main settings.
Overlay Widget
If you don’t want to use the notification, you can use the overlay widget instead. Press the “Show Overlay” button, and you’ll see an expanded control panel.
