Next Track lets you skip songs, mute or stop music using your volume buttons. Next Track works with all standard music players to control music with the screen off. Remap your volume keys while listening to music. Choose single, double and long press actions.

Ignore the reviews and rating, it's just people complaining that the full version costs money. I can't offer this app completely free. There are no ads and I don't collect and sell your personal info, so it has to have a very small price to cover development costs.

This free download lets you try it on your phone to make sure it works. With the free version, a single press of the volume down key will skip to the next track. A double press of the volume down key will lower the volume. The volume up key is not modified. If this is all you need, you're all set! No complicated setup is required.

Free version features
• Skip to next track with one press of volume down
• Decrease volume with more than one press
• Works with the screen off

If you want to do more, upgrade to the Pro version with an easy in-app purchase to unlock all features.

Pro version features (available thru in-app payment)
• Assign actions to volume down and volume up
• Assign functions to single press, double press and long press
• Actions available: next track, previous track, stop, mute, and do nothing
• Works with screen on, with screen off, or both
• Vibrate on key press
• Adjust double press delay

Next Track works only while music is playing. Your volume buttons work normally when music is not playing.

Notes:
-Volume up actions do not work when volume is at max
-Long press actions require a one-time adb command with phone connected to PC
-May not work well with screen off on some Huawei devices

More advanced remapping actions are available in my other app,
