Enabling Bixby is done by pressing and holding the Side or Bixby button, signing into your Samsung account, and completing the on-screen setup.
Enabling Bixby starts with locating the right hardware key on your Samsung Galaxy device. Once you know whether you have a dedicated Bixby key or a multifunction Side key, the setup process takes less than two minutes. This guide covers the official activation steps for Galaxy phones, tablets, wearables, and Galaxy Book laptops.
Enabling Bixby on Your Galaxy Phone: The Exact Steps
The official Samsung setup flow is consistent across modern Galaxy devices. These steps are taken directly from Samsung’s support documentation and apply to current One UI versions.
- Find the right button. On newer phones (Galaxy S20 and later), press and hold the Side button on the right edge. On older models (Galaxy S8, S9, Note 8, Note 9), press and hold the dedicated Bixby button on the left edge, just below the volume rocker.
- Sign in to your Samsung account. If prompted, enter your Samsung account credentials. If you don’t have one, you’ll need to create it during this step.
- Tap Start. This launches the Bixby welcome screen.
- Accept the terms. Read through the pop-up terms and conditions, then tap Continue.
- Speak your first command. After setup completes, press and hold the same button again and speak your request. Bixby will listen and respond.

Setting Up Voice Wake-Up (“Hi Bixby”)
Once the basic button activation is complete, you can enable hands-free voice control. This allows Bixby to respond when it hears its wake-up phrase, even if the phone is idle.
- Open the Bixby app. It is usually located in the Samsung folder on your Apps screen.
- Tap the Settings icon (three vertical dots) within the Bixby app.
- Tap Voice wake-up.
- Tap Voice registration and follow the on-screen instructions. You’ll be asked to say “Hi Bixby” several times so the assistant learns your voice pattern.
- Toggle Wake with “Hi Bixby” to the on position.
What’s the Difference Between the Side Key and the Bixby Key?
This distinction frequently confuses new users because Samsung changed the hardware design a few years ago. Knowing which key your phone uses is the most important prerequisite for a smooth activation.
The Bixby Key is a physical, dedicated button located on the left side of the phone. It was standard on the Galaxy S8, S9, Note 8, and Note 9. A single press opens Bixby Home, while a press and hold activates voice commands.
The Side Key is the multifunction button on the right edge of newer Galaxy phones (Galaxy S20 and later, including the S21, S22, S23, S24, and Z Fold/Flip series). By default, a long press of this button launches Bixby. You can customize this behavior in Settings > Advanced features > Side key, where you can choose between launching Bixby or the Power off menu.
Enabling Bixby on Other Samsung Devices
Bixby isn’t limited to phones and tablets. The setup varies depending on the device category.
- Galaxy Watch: Press and hold the Home button (the physical button on the right side of the watch case) to launch Bixby.
- Galaxy Buds: Open the Galaxy Wearable app on your phone, tap Touch controls, and assign the press-and-hold gesture to launch Bixby.
- Galaxy Book (2022+): Press Fn + B on the keyboard to wake Bixby. You can also click the Bixby icon in the Windows system tray. The shortcut Ctrl + Shift + B works across all Galaxy Book models.
- Family Hub Refrigerator: Bixby is always listening for the “Hi Bixby” wake word on the built-in display. Tap the microphone icon on screen if voice is disabled.

Troubleshooting Common Bixby Setup Issues

|---|---|---|
| Bixby won’t open when I press the button | Not signed into a Samsung account | Complete the sign-in prompt during the initial setup |
| Side key opens the Power menu instead | Side key function is set to Power menu | Go to Settings > Advanced features > Side key and choose “Press and hold” for Bixby |
| “Hi Bixby” doesn’t respond | Voice wake-up not trained | Open Bixby Settings > Voice wake-up > Voice registration |
| Bixby app is missing from the Apps screen | App is hidden or inside the Samsung folder | Open the Samsung folder on the home screen, or search for “Bixby” in the App drawer |
| Bixby keeps crashing or freezes | Corrupted app data or cache | Settings > Apps > Bixby > Storage > Clear cache, then Clear data |
Your Bixby Activation Checklist
Getting Bixby running on your device only requires you to locate the correct button and sign into your Samsung account. Once the initial setup is finished, training the voice wake-up turns Bixby into a genuinely hands-free assistant. If you run into an issue, the troubleshooting table above resolves the vast majority of setup problems—most are caused by a simple account mismatch or a misidentified Side key.
