How to Fix Hey Google Not Working After Switching to Gemini

If your Hey Google stopped working after you switched to Gemini, the problem is usually tied to voice model settings, microphone permissions, or assistant handoff behavior. In many cases, the fix is simple.

Try these steps in order:

1. Open Gemini or Google app settings and confirm voice activation is enabled.
2. Re-train Voice Match if the option appears.
3. Check microphone permission for Gemini and Google.
4. Turn off Battery Saver and test again.
5. Restart the phone once after changing assistant settings.

If it still fails, switch back to the previous assistant temporarily, test hotword detection, and then return to Gemini. That often reveals whether the issue is device-wide or Gemini-specific.

Other common causes:

• Work profile restrictions
• Bluetooth audio confusion
• Multiple language settings
• Background activity limits

If the phone only listens sometimes, treat it as a settings conflict first, not a hardware microphone failure. Most cases are solved by rechecking permissions and voice setup rather than factory resetting the device.
