Gemini AI, Google's advanced digital assistant, now runs on select Wear OS smartwatches, including Samsung Galaxy Watch models. Users gain improved voice command accuracy and access to context-aware features directly from their wrist. However, the installation process and compatibility depend on both your watch's software version and regional rollout status. Understanding these requirements is key for a successful setup.

Check Software and Device Compatibility

Wear OS watches require specific software versions to run Gemini AI. The rollout began with the Galaxy Watch 8 series and is gradually expanding to older models. For full Gemini AI functionality, your device should be running Wear OS 4 or later, with the best results on Wear OS 6 and One UI 8 Watch. Older models like the Galaxy Watch 4 and Watch 5 will receive the necessary updates, but may initially default to Google Assistant until the update arrives.

Step 1: Open the Settings menu on your Galaxy Watch and scroll to About Watch to verify your current Wear OS and One UI Watch versions. If your watch is running Wear OS 4 or above, you’re eligible for the Gemini rollout. For the most reliable experience and integration with Samsung apps, wait for the One UI 8 Watch update, which is scheduled for recent Galaxy Watch models.

Step 2: Connect your watch to Wi-Fi and check for software updates. Open Settings > Software Update and install any available updates. This ensures you have the latest system improvements and bug fixes necessary for Gemini AI.

Install Gemini AI via the Google Play Store

Google is distributing Gemini AI as an update to the existing Google Assistant app on Wear OS. The rollout is staged, so availability may vary by country and device.

Step 1: On your Galaxy Watch, open the Play Store app. Search for "Gemini" or "Google Assistant." If the Gemini update is available, you’ll see the app listed as "Gemini" in the Play Store, but it may still display the Google Assistant logo in the app launcher.

Step 2: Select the app and tap Update or Install. Wait for the installation to complete. The process may take several minutes, especially if your watch is updating multiple system components.

Step 3: Once installed, open the app. If Gemini AI is active, you’ll notice updated branding and new features. If the app still launches as Google Assistant, Gemini may not yet be enabled for your device or region. In this case, functionality will remain similar to Google Assistant until Google completes the server-side activation or your device receives the necessary OS update.

Sideload Gemini AI Using an APK (Advanced Method)

Some users have reported success installing Gemini AI before official rollout by sideloading the Gemini APK. This method is suitable for advanced users comfortable with developer tools and carries minor risks. Sideloading may provide early access, but features can be limited if your device software is not fully compatible.

Step 1: Download the latest Gemini APK file from a trusted source, such as APKMirror or official Samsung/Google channels. Ensure the version matches or exceeds 1.22.5.x, as earlier versions may not support Gemini activation.

Step 2: On your Galaxy Watch, enable developer options by going to Settings > About Watch > Software > Software Version and tapping repeatedly until developer mode is enabled. Then, navigate to Developer Options and turn on ADB Debugging and Wireless Debugging.

Step 3: Use a companion app like "Geminiman Wear OS Manager" on your phone to connect to your watch. Enter the IP address and pairing code shown on your watch in the app to establish an ADB connection.

Step 4: In the companion app, select Install APK and choose the Gemini APK file you downloaded. Approve installation prompts on your watch. After installation, restart your watch to apply changes.

Step 5: Open the Gemini app on your watch to confirm activation. If Gemini still launches as Google Assistant, wait for the next OS update or check for regional restrictions. Sideloading does not bypass server-side activation controls.

Troubleshooting and Tips

  • If Gemini still opens as Google Assistant, your device may not yet be eligible for Gemini activation, or Google has not enabled it for your region.
  • Ensure your Google account language is set to English (or a supported language) in account settings, as some users report this triggers Gemini activation on Wear OS.
  • If you experience battery drain after installing Gemini, monitor app usage in your watch’s settings. Rollouts of new AI features can temporarily increase power consumption.
  • Integration with Samsung stock apps, such as Samsung Health, may be limited until the One UI 8 Watch update is fully deployed. Future updates are expected to improve compatibility and expand Gemini’s capabilities.

Staying current with software updates and checking the Play Store regularly will ensure you receive Gemini AI as soon as it’s available for your Galaxy Watch. For users comfortable with sideloading, early access is possible, but official updates remain the most reliable path for full functionality.
