How to disable Gemini on Android comes down to two settings. Switch back to Google Assistant from the Gemini app’s menu, or turn off the power button shortcut in your phone’s Settings under Gestures. Both take less than a minute to fix.

How to disable Gemini on Android depends on exactly what’s bothering you. Some users want their phone’s assistant switched back to Google Assistant. Others want Gemini to stop opening whenever they hold the power button. These are two different settings, so it helps to know which problem you’re solving.

Once you switch back, Google Assistant responds instead of Gemini whenever you say your wake phrase or use your assistant shortcut.

What If Your Phone’s Menu Looks Different?

Switch From Gemini Back to Google Assistant, or Just Fix the Power Button?
Switch from Gemini back to Google Assistant if you simply prefer your old assistant’s voice and commands. Use the power button gesture settings instead if Gemini popping up unexpectedly is your only complaint. You don’t need to change both settings unless both problems apply to you.
