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

Additional options:

-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"

Used to be able to wake up screen with Bixby button before without root but can't anymore. I checked both the FAQ and used all the advanced setup commands but couldn't find an option. (Yes, I input the commands properly since Bixby + other buttons work even with screen off.) I don't want to b fired for rooting my work phone and can't use power button since plastic trigger fell off Edit 2: That has completely solved my problem. Thank you for all the help troubleshooting. I really appreciate it!

I see now. Try granting the WRITE_SECURE_SETTINGS permission and it should work. See the troubleshooting menu for specific instructions enabling that permission.

Buttons stop working when the screen is black EDIT: I tried to add button mapper to the list of never sleeping apps ( as per dontkillmyapps), but button mapper is not in the list. Edit edit: I reset to default, then gave permission for background usage at the startup screen, rebooted, but alas, "button mapper is still not in the list. Edit edit edit: I sent you an email.

Maybe you need to reboot, or uninstall/reinstall. It should be there. Also try "allow background usage" for Button Mapper.

Update: @ the dev, thanks for the reply! Will do. (5 stars 😉) The app does what it should - for my application use (reprogram a couple buttons on my Chromecast remote). Which makes me happy and encouraged me to spend $5! I had to dock a star though since it seems I will have to pay for each device (even though same account) I use it on... Since the recover purchase button doesn't seem to work. I have 4 devices I wanted to reprogram and while another $15 is no huge deal, I rarely use those TVs.

It will work on unlimited devices. Make sure you install from the Play Store with the purchasing account. Google Play is terrible on multiple devices. If pro version doesn't show up, wipe Google Play Store data and reboot.
