Button Mapper: Your Ultimate Tool for Customizing Hardware Buttons

Button Mapper revolutionizes the way you interact with your device, allowing you to remap custom actions to your volume buttons and other hardware keys with ease. Whether you want to launch an app, execute a shortcut, or trigger a custom action, Button Mapper makes it possible with a single press, double tap, or long press.

This powerful app supports remapping of most physical or capacitive keys and buttons, including volume buttons, some assist buttons, and capacitive home, back, and recent apps keys. Button Mapper extends its functionality to buttons on gamepads, remotes, and various peripheral devices, offering a versatile solution for all your customization needs.

While most actions do not require root access, some advanced features may need an adb command from a connected PC if your device is not rooted. Note that Button Mapper does not function when the screen is off unless your device is rooted or you use an adb command.

Here are some exciting examples of what you can achieve with Button Mapper:

For troubleshooting:

• Ensure the Button Mapper accessibility service is enabled and allowed to run in the background
• Note that 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

Button Mapper uses Accessibility services to detect when physical or capacitive buttons are pressed, enabling them to be remapped to custom actions tailored to your needs. Rest assured, Button Mapper does not collect or share any of your personal information, ensuring your privacy is respected.

The app also utilizes the Device Administrator permission (BIND_DEVICE_ADMIN) to lock the screen if the "Turn screen off" action is selected. To remove this permission, simply open Button Mapper, click on the menu (three dots in the upper right corner), and select "Uninstall."
