How to Easily Remap the Bixby 2.0 Button on Samsung Galaxy Note 9

No root required!

The Samsung Galaxy Note 9, which was released earlier this year, features Samsung’s latest Bixby 2.0 which came equipped on last year’s Samsung Galaxy S8 and Galaxy S8+. Some say that the Bixby 2.0 is more if a downgrade than an update, however, as certain features were stripped out – luckily, there are a few easy ways to remap the Galaxy Note 9’s Bixby 2.0 button and customize it to your liking.

There are a handful of remapping apps for Bixby 2.0, but we’re going to show you the two best, after a lot of testing was done by the development community. Read on to find out how to remap the Bixby button on Samsung Galaxy Note 9, but be warned that these apps will require ADB on your computer – see Appual’s guide “How to Install ADB on Windows”.

App #1: Button Mapper

Samsung Galaxy Note 9 Bixby 2.0 remapper Button Mapper.
  • Developer: flar2
  • Price: Free+

Button Mapper lets you remap any button on your phone, but specifically for our purposes, it lets you remap the Bixby button on the Galaxy Note 9. This app is more reliable than option two, but it does have one downside. You need to run the script every time you reboot your phone. You can follow the tutorial below to set it up.

  1. Install Button Mapper from the Google Play Store.
  2. Set up ADB on your computer. You can follow this guide to get it installed.
  3. Enable ADB by going to Settings > About Phone > Software Information and tap build number 7 times. Once you do this enter your password and go back twice. You can enter the developer options menu now. Just toggle the USB Debugging switch to enable ADB.
  4. Open the Button Mapper app, at the bottom of the window, there will be a popup asking you to enable accessibility services. You then just enable accessibility services for Button Mapper.
  5. Select the Bixby Button option at the top of the app. Then click the customize button. Once you do this you will need to run the following commands:
adb shell sh /data/data/flar2.homebutton/keyevent.sh
adb shell sh /data/data/flar2.homebutton/keyevent.sh -d

You will need to run this second command every time you reboot your phone. This will also disable Bixby Voice. If you don’t disable Bixby Voice, it will open every time you press the button along with what you have it remapped to. You can re-enable Bixby Voice with the following command:

adb shell sh /data/data/flar2.homebutton/keyevent.sh -e.

You select whatever option you want to use in the single tap and long press menus. You can set it to do things like open Google Assistant or toggle the flashlight.

This app seems to be a bit better in use because it disables Bixby Voice and remaps it. The downside is that you will have to run the ADB command every time you reboot your phone. If you don’t want to have to run the command every time you reboot your phone, option 2 will be for you.

App #2: bxActions

bxActions app for Galaxy Note 9 Bixby 2.0 remapping.
  • Developer: Jawomo
  • Price: Free+

bxActions is an app that has been doing Bixby remapping since the Samsung Galaxy S8 and Samsung Galaxy S8+ launched last year. This app is pretty reliable for remapping Bixby on the Samsung Galaxy Note 9, but Bixby Voice is still installed so there could be some compatibility issues with that. The developer is actively developing the app so if you do find any bugs, you should expect them to be fixed.

  1. Join the open beta for bxActions then install the app.
  2. Install ADB on your computer. You can follow this guide to get it installed.
  3. Enable ADB by going to Settings > About Phone > Software Information and tap build number 7 times. Once you do this enter your password and go back twice. You can enter the developer options menu now. Just toggle the USB debugging switch to enable ADB.
  4. Open bxActions and follow the prompts to give it the permissions it needs.
  5. Select the Bix button options and click the red box that says “please unlock permissions using a PC”
  6. Run the two commands:
adb shell pm grant com.jamworks.bxactions android.permission.WRITE_SECURE_SETTINGS
adb shell pm grant com.jamworks.bxactions android.permission.READ_LOGS

Once you do this close and reopen the app.

You can now select the option you want to use to remap the Bixby button on the Samsung Galaxy Note 9. This app has actions like Google Assistant and the flashlight toggle as well.

This app does work well, but it’s not always as reliable as Button Mapper in my experience. It has the great upside of only needing to be enabled once. You don’t even need to run the adb command, but it does make the app faster and more reliable. This app is by no means bad—I would say it’s probably the best for its function. Just sometimes, I have found it to be unreliable on my Galaxy Note 9.
