[App] Button Mapper – Remap your keys

Button MapperButton Mapper makes it easy to map custom actions to your volume buttons, home button, back and recent apps keys. Remap your buttons to launch any app, shortcut or custom action.

Assign custom actions to single presses, double taps and long presses of your phone’s hardware buttons. Root is not required.

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 many devices by ASUS, HTC, OnePlus, Xiaomi and other manufacturers.

Button Mapper user reviews :

Really good but there is an extremely annoying double vibration now when I use the back button, one when I press and one when I release. . . . Also just as an idea maybe you could add the ability to have shortcuts for when multiple buttons are pressed simultaneously, eg vol up + down for screenshot. EDIT: Nope that disables both, but oddly enough if I set vibration to 100 for the back button the 2nd vibration stops, so I’m happy now

    You can get rid of the double vibration by going to Settings – Sound and notification and disabling “Vibrate on tap”

Just what I needed for a broken hardware home button, was able to remap the recent to handle the job.

Works perfectly on my Pixel.
