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"

Fantastic While the setup is a bit complicated, it is absolutely worth the effort. When I got a Galaxy S9 (previously had an S7), I was immediately annoyed by the dedicated Bixby button. As I don't want to root my device at this time, I tried several Play Store apps that claimed to support remapping it but this was the only one that worked. It works perfectly. Furthermore, it allows remapping and overloading all of my phone's hardware buttons. Continues to work great on my Galaxy S10.

After at least an hour of fiddling and developer emails, I finally got it to work. The developers were very helpful. It took many, many tries to get the settings menu unfrozen because it wouldn't scroll but one good whack on the table seemed to dislodge the Android cholesterol. I needed this app to perform one solitary function, and it did. Pixel 6 turd.

Love this app for adding functionality to CCwGTV. Thank you for your response. Deleting and re-adding the button, which seems to have changed designation, partially fixed my issue except the chose YT app screen would still show up. Turning on Alternative Button hadling fixed that. Excellent app. 🙏 RESOLVED: Recently it has stopped working for the YouTube button. The YouTube button now has a system function added that allows you to hold it to select weather you want it to open YT or YTTv.
