How do I change my Bixby button to power button on Samsung?

Samsung really wants you to use its Bixby virtual assistant. The problem is that Bixby is inferior to Google Assistant and Alexa in basically every way. The other problem is that, by default, Bixby is tied to a long press of the power button. This can be confusing if you go to turn off or reboot your phone.

Out of the box, you need to press and hold the power button and volume down to turn off or reboot your Galaxy S21. This is how you do it on an iPhone and it can be quite irritating for some people.

Bixby is Samsung’s answer to voice assistants like Siri and Google Assistant, and the company introduced a dedicated button for it with the Samsung Galaxy S8. This proved controversial — the button was easy to hit accidentally, and years later, Assistant is still widely considered superior. Bending to public demand, Samsung introduced Bixby button remapping with the Android 9.0 Pie and One UI update.

In this tutorial, we’ll show you how to remap the Bixby button on all the Samsung Galaxy devices that still have it.

QUICK ANSWER

If you have a compatible phone with Android 9.0 (or later) and One UI, you can remap the Bixby button by tapping it, then going to Menu > Settings > Bixby key. Choose either Single press to open Bixby or Double press to open Bixby, flip the toggle switch, and pick an app or quick command you want to run. You'll need third-party apps or APKs to reassign it to Google Assistant.

How do I change my Bixby button to power button on Samsung?

Thankfully, Samsung has moved away from having a Bixby button. Most recent Galaxy devices have a side button customizable from the jump.

The methods below require a device to have One UI and the Android 9.0 Pie update or later. The following phones should be able to use this tutorial:


How to natively remap the Bixby button

How do I change my Bixby button to power button on Samsung?

Assuming you’ve updated to the latest possible Samsung software on compatible devices, you can do limited remapping of the Bixby button without any third-party tools.

  • Open Bixby Assistant Home by pressing the Bixby button one time.
  • Tap Menu (indicated by three horizontal lines) and select your device.
  • Tap Settings, then Bixby key.
  • Choose either Single press to open Bixby or Double press to open Bixby.
  • Flip the toggle switch underneath either option.
  • Select an app or quick command you want to run.

The beauty is that you can make the button do two different things, depending on whether you hit it once or twice — you can even keep Bixby around, for instance setting up a double-press command that runs driving-related actions. Samsung warns that you may lose remapping if you reset Bixby or deactivate an assigned app or command, but you should be able to restore it by following the process above.

There are some restrictions. You can’t natively select Google Assistant or Amazon Alexa for the button, but all other apps should be available.


How to remap the button to Google Assistant

How do I change my Bixby button to power button on Samsung?

People like remapping the Bixby button to Google Assistant, which is the default voice assistant on most other Android phones. As we said, you can’t do this directly using Samsung’s software, but there is a workaround:

  • Download the Bixby Button Assistant Remapper app from XDA. Install it on your device like you would any other third-party APK. Here’s our tutorial if you need help.
  • Return to Samsung’s native Bixby remapping options, but select the Bixby Button Assistant Remapper as your triggered app.
  • Press the Bixby button to run the command for the first time. It will ask what assistant you want to use. Select Google Assistant, then Always.

This worked well in our testing, and you don’t have to mess with anything once it’s up and running. We’re not thrilled that Samsung forces this type of detour, but installing a third-party APK isn’t the worst solution.


Remap Bixby with apps from Google Play

How do I change my Bixby button to power button on Samsung?

One final method for remapping the Bixby button is third-party apps from the Google Play Store. This isn’t as clean as Samsung’s approach, but these apps can do things the native OS can’t. Examples include remapping the volume keys, or having the Bixby button toggle the flashlight on and off.

Bixbi Button Remapper is one of our favorites. It’s free and includes some fun functions. Button Mapper works with a bunch of buttons but also includes support for Bixby. Search the Play Store for more if those two don’t work.
