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
-Themes
-Change back and recents buttons
-Customization of haptic feedback (vibration) on button press and long press

Actions that can be mapped to buttons or keys:
-Launch any app or shortcut
-Disable the button
-Broadcast intents (PRO)
-Run scripts (PRO)
-Camera shutter
-Turn screen off
-Toggle flashlight
-Quick settings
-Show notifications

Buttons supported:

-Volume up
-Volume down
-Most camera buttons
-Many headset buttons
-Custom buttons: add other buttons (active, mute, etc) on your phone, headphones, gamepads, TV remote and other peripheral devices

Additional options:
-change the long press or double tap duration
-delay initial button press for better double tap operation

-plus many more customizations

Troubleshooting:
-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"
Remap hardware buttons to launch any app, shortcut or action

Very good and useful. Been using this for 2 years now. Thank you flar for this amazing app. There is a problem I have sometimes where the shortcuts I assign sometimes deactivate so I have to go back into the app to reactivate. Also, I have a double press shortcut that takes me to recents, but if I accidently press the volume up button, and then double tap, the system deactivates or something, and that double tap isn't responsive.

First problem is Samsung killing the service, you need to make sure it's not putting the app to sleep, also allow background usage no restrictions. Second is by design, disable volume panel bypass to change the behavior

wanted to use this app for healthier scrolling. however it is not possible to fine tune the scroll and the original setting will not scroll all the way down the page which makes it inneficient. other options are nice and the button mapping works well. please make something for the scroll option, it's a real life changer.

Useful features locked behind a paywall, I just wanted my volume keys to control my media volume during a call, greedy app developer wants 10+$ for this feature. Use key mapper it's free and works better than this copycat app. Also this developer is very sassy, so I'm giving one bonus star to my original review for that.

I just want everything to be free. I don't want to pay for anything. I'm cheap. Is that what you meant to say? The copycat apps do not work better, this one is far better for daily use. You get what you pay for.
