On most recent Android phones, the quickest way to stop Google Assistant—or Gemini—from opening is to remove it as the phone’s default digital assistant. The change takes a few taps and does not uninstall Google or Gemini.
Turn off Google Assistant on Android
- Open Settings.
- Tap Apps.
- Tap Default apps.
- Tap Digital assistant app.
- Tap Default digital assistant app.
- Select None.
Google Assistant or Gemini should no longer open when you use the phone’s assistant gesture or shortcut. This setting disables the default assistant; it does not delete the apps or your Google account.
Can’t find “Digital assistant app”?
Android manufacturers use slightly different names and menu layouts. In Settings, use the search box and look for digital assistant app. You may instead see Device assistant app or Assist app.
Stop “Hey Google” from opening Gemini
Removing the default assistant may not disable hands-free activation in the Gemini app. If saying “Hey Google” still starts Gemini:

This stops voice activation. It may not remove a separate power-button, home-button, or corner-swipe shortcut.
If the power button still opens an assistant
Some Android phones assign the assistant to a long press of the power button or side key. Look for this setting under:
Settings → System → Gestures → Press and hold power button

Choose the power-menu option instead of the assistant. Menu names vary, so search Settings for power, side button, or gesture. On Samsung phones, check Settings → Advanced features → Side button.
Why older instructions may not work
Some older guides use Google app → profile picture → Settings → Google Assistant → General. That Google Assistant screen may no longer exist on phones that have moved to Gemini. Google’s current Android route is the Default apps → Digital assistant app setting, while Gemini’s hands-free control is under Talk to Gemini hands-free.
Google is also discontinuing classic Google Assistant on Android mobile devices beginning September 4, 2026, with Gemini becoming the Android assistant experience. The change is expected to roll out over several weeks.

If you only want the phone to stop recognizing your voice, turn off Voice Match instead. This prevents “Hey Google” from responding to your voice, but it can also affect Voice Match-dependent features and personal results. For a complete shutdown of the phone’s assistant shortcut, selecting None under the default digital assistant setting is the more direct option.

Does choosing “None” uninstall Google Assistant or Gemini?
No. It only removes the assistant as the phone’s default digital-assistant shortcut. Google, Gemini, and Assistant remain installed unless you remove or disable them separately.
