How to Activate Google Assistant on Your Phone

This guide walks you through turning on and setting up Google Assistant on both Android and iPhone. You’ll learn the quickest ways to summon it, whether by voice, gesture, or touch, and how to fix common setup issues.

What You’ll Need

• A phone running Android 6.0 or newer, or an iPhone with iOS 12 or newer.
• The Google app (Android) or the Google Assistant app (iPhone) installed from the official app store.
• A stable internet connection (Wi-Fi or mobile data) for the initial setup.
• A Google account you’re signed into on the device.

Step-by-Step

For Android Phones

1. Open the Google app. Find the app icon (usually a colorful “G”) in your app drawer or on your home screen. If you don’t see it, download it from the Google Play Store.
2. Tap your profile picture. It’s in the top-right corner of the app’s home screen. If you’re not signed in, you’ll be prompted to sign in to your Google account.
3. Go to Settings. In the menu that appears, tap “Settings” and then “Google Assistant.”
4. Tap “General.” You’ll see a toggle labeled “Google Assistant.” Make sure it’s switched on. If it’s already on, you’re good to go.
5. Set up Voice Match (optional but recommended). Back in the Assistant settings, tap “Hey Google & Voice Match.” Toggle on “Hey Google” and follow the prompts to train the Assistant to recognize your voice. This lets you summon it hands-free.
6. Choose your Assistant language. In the same Voice Match menu, tap “Language” and pick the language you’ll speak. This helps recognition accuracy.
7. Test it. Say “Hey Google, what’s the weather?” or press and hold the home button (or the side button if you’re using gestures) to see if the Assistant responds.

For iPhone (iOS)

1. Install the Google Assistant app. Go to the App Store, search for “Google Assistant,” and download the official app from Google LLC.
2. Open the app. Tap the Assistant icon on your home screen.
3. Sign in. If you’re not already signed in, you’ll be asked to choose a Google account. Tap “Continue” and accept the terms.
4. Grant permissions. The app will ask for permission to access your microphone and notifications. Tap “Allow” for both. These are needed for voice recognition and for the Assistant to send you proactive alerts.
5. Enable “Hey Google” (optional). In the app, tap your profile picture, go to “Settings,” then “Hey Google.” Toggle it on and follow the voice training prompts. This allows hands-free activation even when the app is in the background.
6. Use the app. To activate the Assistant, open the app and tap the microphone icon, or simply say “Hey Google” if you’ve enabled that feature. You can also add a widget to your home screen for quicker access.

Common Mistakes

• Skipping the Google app update. An outdated Google app may not have the latest Assistant features or may have bugs. Always update it from the Play Store or App Store before troubleshooting.
• Not granting microphone permission. If you denied the mic permission during setup, the Assistant won’t hear you. You can re-enable it in your phone’s system settings under “App permissions.”
• Using the wrong wake phrase. On Android, the default is “Hey Google” or “OK Google.” On iPhone, it’s “Hey Google” only. Saying “OK Google” on iOS won’t work.
• Disabling the Assistant in the Google app settings. Some users accidentally toggle off the Assistant while trying to turn off other features. Double-check that the main “Google Assistant” toggle is on.
• Expecting it to work without a Google account. You must be signed into a Google account. The Assistant is a personalized service and requires an account to function.

Tips

• Use the squeeze gesture (Pixel phones). If you have a Pixel 2 or later, you can squeeze the bottom corners of the phone to summon the Assistant. This is faster than voice or button.
• Set up a routine. In Assistant settings, you can create routines like “Good morning” that trigger multiple actions (e.g., turning on lights, reading the news) with one command.
• Use the Assistant’s “Continued Conversation.” This feature lets you ask follow-up questions without repeating “Hey Google.” It’s available on Android and can be enabled in Assistant settings under “Continued Conversation.”
• Customize your Assistant’s voice. You can choose from different voice options (like red, orange, or green) in the Assistant settings to make it more pleasant to listen to.
• Add a home screen shortcut. On Android, long-press the Google app icon and drag the “Assistant” shortcut to your home screen. On iPhone, use the “Shortcuts” app to create a voice command that opens the Assistant.

Troubleshooting

• Assistant not responding to “Hey Google.” First, check if Voice Match is enabled in the Google app settings. If it is, retrain your voice model by going to “Hey Google & Voice Match” and tapping “Retrain voice model.” Also, make sure your phone’s language matches the Assistant’s language.
• Assistant opens but doesn’t hear me. This is usually a microphone permission issue. Go to your phone’s Settings > Apps > Google (or Google Assistant) > Permissions and ensure Microphone is set to “Allow.” On iPhone, go to Settings > Privacy > Microphone and toggle on Google Assistant.
• Assistant says “Can’t connect.” This often means your internet connection is unstable or the Google servers are having issues. Try toggling airplane mode on and off, or restarting your router. If the problem persists, check Google’s status page (but don’t rely on it for immediate fixes).
• Assistant is not available on my device. Some budget Android phones or older models may not support Assistant. Check that your device meets the minimum requirements (Android 6.0+). If it does, try clearing the Google app’s cache: Settings > Apps > Google > Storage > Clear Cache.
• Assistant keeps closing or crashing. This is often due to a corrupted cache or an outdated app. Force-stop the Google app, then reopen it. If that doesn’t work, uninstall updates for the Google app (Settings > Apps > Google > Uninstall updates) and then reinstall them from the Play Store.
• On iPhone, the Assistant app doesn’t respond to “Hey Google” when the screen is locked. This is a known limitation on iOS. The Assistant can only listen for the wake phrase when the app is open or running in the background. For hands-free use while the phone is locked, you’ll need to use Siri instead.
