Keycode for Bixby button is 703



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

It works for me. My Bixby button is regulating the volume down
