Samsung introduced a brand new virtual voice assistant in the Galaxy S8 / S8+ which can be accessed from a dedicated physical button on the left side of the phone. It has to be said that Samsung’s pulled off a brave move by including a dedicated hardware button for its own search assistant in the new S8 and S8+ smartphones.

Steps to Manually Remap Bixby on Galaxy S8/S8+ with Root

Before starting remapping method, don’t forget that Keycode for Bixby Button is 703 and note it down somewhere safe so that you can set Bixby button back to Bixby voice search as and when needed. Also note that the following guide works only on rooted Samsung Galaxy S8/S8+ phones. Do not attempt it on non-rooted devices.

Step 1 – Make sure that your device has a root explorer tool installed on it. ES File Explorer is currently the best option on Android.

Step 2 – Now launch the file explorer on your device and navigate to /system/usr/keylayout.

Step 3 – Here, rename the file Generic.kl to Generic.txt.

Step 4 – Next, open this file using a text editor.

Step 5 – Search 703 in Generic.txt, which will take you to this entry: # input_fw Intelligent Key for Dream key 703 WAKE

Step 6 – For example, you want to set Bixby button to launch the Music app. For that, change the above entry to # input_fw Intelligent Key for Dream key 703 MUSIC

Step 7 – That’s all.

Important Note: Once done, it is very important that you rename the ‘Generic.txt’ file in step-3 above back to ‘Generic.kl’, otherwise hardware key will get stuck after the reboot and you won’t be able to use it.

Other Bixby Button Options:

Instead of the music app in step-6 above, you can replace ‘MUSIC’ in the entry with following options to set Bixby button for a different task.

VOLUME_DOWN – volume down
VOLUME_UP – volume up
HOME – launches Home button
POWER – enters Power menu
MUSIC – opens music player
CAMERA – starts camera app
APP_SWITCH – Recent apps button
VOICE_ASSIST – launches Google Assistant
