How to Set Gemini as Your Default Assistant on Android

Google has made Gemini the primary assistant on many Android devices. On newer phones it may already be the default. On others you can switch from Google Assistant in a few steps.

Once Gemini is your mobile assistant, long-pressing the power button, swiping from a bottom corner, or saying “Hey Google” opens Gemini. It handles everyday tasks, answers questions, and connects to your Google apps. Smart displays, speakers, and cars continue to use Google Assistant.

This guide covers the official steps from Google’s support documentation, how to confirm the setting, and tips for getting the most from voice and touch shortcuts.

Check Your Current Assistant

Start by seeing what is already set. Open Settings on your Android phone. Tap Apps, then Default apps. Look under Digital assistant app. If it shows the Google app, you can choose Gemini inside it. If another app is listed, select the Google app first.

Some phones place the same option under System or Search. Using the Settings search bar for “digital assistant” or “default apps” finds it quickly on most devices, including Samsung Galaxy and Pixel models.

Set Gemini Through the Google App

The most common path starts in the Google app:

1. Open the Google app.
2. Tap your profile picture or initial in the top right.
3. Tap Settings, then Google Assistant (or Gemini if already listed).
4. Tap Digital assistants from Google.
5. Select Gemini.
6. Follow the on-screen prompts to confirm and complete setup.

If you have never used the Gemini app, download it from the Play Store first. The switch works for personal Google accounts and many work or school accounts that have access to Gemini.

Set Gemini in Device Settings

On some devices the option appears directly in system settings:

1. Open the Settings app.
2. Tap Apps, then Assistant (wording can vary slightly).
3. Tap Digital assistants from Google.
4. Select Gemini.
5. Confirm the switch.

After the change, long-press the power button or swipe up from a bottom corner. Gemini should appear instead of the older Assistant overlay. On devices that ship with Gemini pre-set, simply open the Gemini app or use the same shortcuts.

Turn On Voice Activation

For hands-free use, enable “Hey Google”:

1. Open the Gemini app.
2. Tap the menu, then your profile picture or initial.
3. Tap Settings.
4. Tap Talk to Gemini hands-free.
5. Turn on Hey Google and complete Voice Match setup so the phone recognizes your voice.

Once active, saying “Hey Google” starts a Gemini conversation. You can also ask questions while the screen is locked on supported devices. Google notes that other Assistant-powered devices in your home stay on Assistant.

Customize Shortcuts and Behavior

You control when Gemini appears:

• Power or side button: Search Settings for “power button,” “side button,” or “gestures” to decide whether a long press opens Gemini.
• Lock screen: In Gemini settings look for an option to allow or block activation while the device is locked.
• Navigation: Gesture or button navigation can include an assistant shortcut. Adjust it under System navigation if needed.

If Gemini activates too often, turn off Hey Google or change the power-button action. You can switch back to Google Assistant at any time from the Gemini app menu by selecting Switch to Google Assistant.

Practical Tips for Daily Use

Gemini works best when it has the right permissions and connections:

• Allow microphone access so voice input works reliably.
• Connect Google apps such as Gmail, Calendar, and Maps under Connected Apps or Personal Intelligence for more useful answers.
• Update both the Google app and the Gemini app from the Play Store so you receive the latest interface and model improvements.
• On Pixel and recent Samsung devices, Gemini Live voice conversations and camera or screen sharing become available once the assistant is set.

If the switch does not stick, clear cache for the Google app or restart the phone, then repeat the steps. Device manufacturers sometimes place the Digital assistant setting in slightly different menus; the Settings search bar almost always locates it.
