Button Mapper

Button Mapper turns every hardware key into a shortcut powerhouse

Button Mapper is a powerful customization tool that lets you redefine what your physical buttons do, transforming underused keys into productivity and accessibility shortcuts. Instead of being stuck with standard volume or navigation behavior, you can assign single, double, or long presses to actions that actually match your routine.

The highlight is versatility. Volume keys, capacitive home, back and recent buttons, certain assist keys, and even many gamepads and TV remotes can be remapped. This opens up clever possibilities: long-press a volume button to toggle the flashlight, double-tap to open your favorite messaging service, or hold a key to launch the camera and snap a photo instantly. Power users can go further by triggering custom intents, scripts, or commands, effectively turning hardware buttons into automation triggers.

The interface is clean and logically organized, separating each button and press type so you always know what you are modifying. Changes apply quickly, and in everyday use the response is snappy and reliable, with optional haptic feedback adding a polished touch in the pro version.

There are, however, some technical caveats. For advanced features such as simulating keycodes or making everything work with the screen off, you’ll need either root access or to run an adb command from a computer. This extra step might feel intimidating for less technical users, even though basic remapping works without it.

The optional pro upgrade unlocks useful extras like volume-key swapping on orientation change, finer vibration control, and pocket detection to avoid accidental presses, making it especially attractive for power users.

Overall, Button Mapper is an excellent choice for anyone who wants more control over hardware buttons, from casual tinkerers to automation enthusiasts seeking deep customization.
