How to remap the Bixby button on the Galaxy S8 and S8+ using root

795

The Samsung Galaxy S8 and Galaxy S8+ came with a dedicated Bixby button to launch the virtual assistant but the service wasn’t fully for launch. Many apps now exist to remap this button to something more useful but what about if you have root access and don’t want to install an app?

Simply use this procedure to remap the Bixby button on the Galaxy S8 and S8+ with root access.

1. Go with any root Explorer (I’m using Solid Explorer) to
/system/usr/keylayout
2. Rename the Generic.kl to Generic.txt
3. Open this file with an text editor
4. Search for 703 to get following entry:
# input_fw Intelligent Key for Dream key 703 WAKE
5. Change it to whatever you want. I simply tried following:
# input_fw Intelligent Key for Dream key 703 VOLUME_DOWN
!! 6. Rename it back to Generic.kl (otherwise you won’t be able to press any hardware button after reboot; as me lol)
7. Check permissions
8. Restart your device

Some of the possible assignments include:

VOLUME_DOWN – sets volume down
VOLUME_UP – sets volume up
HOME – Homebutton
POWER – Powermenu
MUSIC – starts your favorite music player
CAMERA – starts camera app
APP_SWITCH – Recent apps button
VOICE_ASSIST – Google Assistant

Now you can remap your Bixby button to pretty much whatever you like. Drop us a comment and let us know if you found this useful.
