The Galaxy S10 does more than just deliver a new Infinity O panel, give you the ability to wirelessly charge other devices and (on the S10 and S10 Plus at least) unlock the phone with an in-display fingerprint sensor. It also lets you do what you want with the Bixby button on the side of the phone.
Thanks to the OneUI interface that’s included on the Galaxy S10, you can remap the button dedicated to Samsung’s digital assistance. (Since this capability is tied to the latest version of Samsung’s software, the feature isn’t limited to the S10, either — if you have a Galaxy S8 or S9 that’s been upgraded to OneUI, you can remap the Bixby button, too.)
You can’t alter the key to trigger Google Assistant, but otherwise, the Bixby button can now support a variety of different apps and actions. Here’s how to reconfigure the button to point to one of your choosing:
1. Press the Bixby key on the left side of the S10 to call up Bixby voice
2. Tap the on-screen menu, represented by three vertical dots.
3. Tap Settings.
4. Scroll down to the Bixby Key menu item and tap it.
5. Select either Single Press to Open Bixby or Double Press to Open Bixby. Whichever shortcut you select, the other will be open to be mapped to an app or command other than Bixby. For the sake of this how-to, let’s select Double press to open Bixby.
6. Below Double press to open Bixby, tap the Use Single Press toggle to turn on a single-press shortcut for an app or quick command.
7. Toggle the setting on.
8. Tap either Open App or Run Quick Command, depending on what you want to make the shortcut.
9. Select the specific app or command you the Bixby key to direct to.
That’s it — you’ve remapped the Bixby key. What’s more, you can always return to this menu in the future to change your custom shortcut or turn the feature off entirely.
