Button Mapper: Remap your keys

Button Mapper is a versatile tool that empowers you to remap hardware buttons on your device to perform a variety of actions, enhancing your user experience. Whether you want to launch apps, shortcuts, or execute custom actions, Button Mapper makes it simple and efficient. With support for single presses, double presses, and long presses, you can customize your device's buttons to suit your needs.

The app supports the remapping of most physical or capacitive keys, including volume buttons, assist buttons, and capacitive home, back, and recent apps keys. Moreover, Button Mapper extends its functionality to many gamepads, remotes, and other peripheral devices, making it a comprehensive solution for button remapping.

While root access is not necessary for most actions, certain advanced features may require an adb command from a connected PC if your device is not rooted. It's important to note that Button Mapper does not function when the screen is off unless your device is rooted or you've executed an adb command.

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

• Use a long press to toggle your flashlight

Additional customization options include:

For troubleshooting, ensure that the Button Mapper accessibility service is enabled and allowed to run in the background. Note that Button Mapper does not work with onscreen buttons or the power button, and the available options depend on the buttons present on your device.

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

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