Button Mapper - Remap Your Phone Buttons Without Root

Remap Android phone hardware buttons (including capacitive keys) to launch any app, shortcut or action. Assign custom actions to button presses, double clicks and long presses.

Button Mapper can remap physical or capacitive keys and buttons, such as volume buttons, the home button on Samsung Galaxy devices, the camera button on Sony devices, and the capacitive home, back and recent apps keys found on some devices by ASUS, HTC, OnePlus, Xiaomi and other manufacturers. Best of all, Button Mapper does NOT require root.

Key remapper functions do not work with onscreen buttons (such as soft keys or the navigation bar) and the power button. This app does not work while the screen is off. The options shown in the app depend on the buttons available on your phone. The free version shows all available options for your device. However, some of these options are reserved for PRO users. The PRO version unlocks these options.


Button Mapper respects your privacy and confidentiality. It does not collect or share any of your personal information. It does not monitor or log what you type on your screen. It does not contain ads.
