About this app

Button Mapper makes it easy to remap custom actions to your volume buttons and other hardware buttons. Remap buttons to launch any app, shortcut or custom action with a single, double press or long press.

Button Mapper can remap most physical or capacitive keys and buttons, such as volume buttons, some assist buttons, and capacitive home, back and recent apps keys. Button Mapper can also remap buttons on many gamepads, remotes and other peripheral devices.

Root is not required for most actions, however some require an adb command from a connected PC if not rooted. Button Mapper does not work when the screen is off unless your device is rooted or you run an adb command.

A few examples of remapping you can do with Button Mapper:
-long press to toggle your flashlight
-remap your TV remote control
-press to broadcast custom intents, scripts or commands
-long press to open camera and take a photo
-double tap to launch your favorite app or shortcut
-double tap to open your notifications
-swap your back and recent apps keys (capacitive buttons only!)
-use your volume buttons to adjust screen brightness
-long press to toggle "do not disturb" mode
-and much more

Additional features unlocked in the pro version:
-Simulate keycodes (requires adb command or root)
-Swap volume keys on orientation change
-Default to ring volume on Pie or later
-Pocket detection
-Change back and recents buttons
-Customization of haptic feedback (vibration) on button press and long press

-Make sure Button Mapper accessibility service is enabled and allowed to run in the background
-Button Mapper does not work with onscreen buttons (such as soft keys or the navigation bar) or the power button.
-The options shown in the app depend on the buttons available on your phone. Not all phones have home, back and recents buttons!

This app uses Accessibility services. Accessibility is used to detect when the physical or capacitive buttons are pressed on your device so they can be remapped to custom actions to accommodate your needs. It is not used to see what you type. Button Mapper does not collect or share any of your personal information, it is safe and your privacy is respected.

This app uses the Device Administrator permission. (BIND_DEVICE_ADMIN)
This permission is used to lock the screen if the "Turn screen off" action is chosen. If you want to remove this permission, open Button Mapper, click on the menu (three dots in the upper right corner) and select "Uninstall"

Was a little skeptical but this is just what the doctor ordered. I listen to podcasts, music, etc through my discreet earbuds at work and reaching under my hat to switch songs has always been a hassle and makes me paranoid that I'll get caught. With an app like this, I can change songs more discreetly by just reaching into my pocket for a few secs. A little bummed that it doesn't work when the screen is off but that's no big deal, just one extra button to press and still works when locked.

The people that arent rating this app highly are very obviously not setting it up intuitively. Duh, it's not useful to remap the 'single press' volume down function. But let's say the reaped the 'double press' of the volume down key to something else. The oringal volume control is then retwkned, but you've gained instant access to let's say the voice recorder. That speed might allow you to catch some valuable conversation before it's over. That's a very basic example, the apps potential is huge.

this is a very great app, it works very well and it's very easy to use. I paid for access to the assistant button remap and it well... works. I mapped my assistant button to play and pause my music, and well sometimes it'll have a 7 second delay, and sometimes it won't pause at all! it's completely and entirely unreliable, and I need it to work within at least the second. when I have people coming up to me I need to be able to pause my music at a moments notice, but I can't. on LG G8X
