How to Fix OK Google Command Not Working on Android

One of the easiest and coolest ways to launch the Google Assistant on an Android smartphone is to call out the summoning command – OK Google. However, Google Assistant is surprisingly unresponsive to the command for some users. To help you fix this anomaly, we have listed seven possible solutions in the section below.

Also, it’d be a bit weird if you keep utter ‘OK Google’ with different tones and expressions. That won’t fix the glitch. A simple device restart would get the ‘OK Google’ command working again. If that doesn’t do the trick, try the fixes below.

1. Try an Alternate Command

The Google Assistant is popularly activated by many Android users using the ‘OK Google’ hotword. On some devices, the Assistant only responds to “Hey Google” surprisingly. That said, some users can activate the Assistant using both hotwords — ‘OK Google’ and ‘Hey Google’.

If your device’s Google Assistant doesn’t respond to the ‘OK Google’ command, try ‘Hey Google’. And if that doesn’t work as well, then there’s most likely some hiccups with your Google Assistant app or its voice command configuration.

2. Clear the Google App Cache Data

Clearing an app’s cache data can help you fix the app when it slows down, malfunctions, or when some of its features are not working. Clearing the Google app’s cache can (and should) help get the Google Assistant OK Google command working on your device again.

Simply launch the Android Settings menu and navigate to Apps & notifications > App info > Google > Storage & cache and tap the Clear Cache button.

5. Disable Battery Saver

Android’s built-in Battery Saver could also temporarily disable the Google Assistant if it detects that the feature is excessively draining your device’s battery. And that would cause the OK Google command not to work.

6. Update Google Play Services

To use Google Assistant, your Android device must have Google Play Services updated to the latest version at all times. Visit the Google Play Services page on the Google Play Store to install or update the app on your device.

7. Retrain Google Assistant

Another reason why the OK Google command doesn’t work on your Android device could be because Google Assistant no longer recognizes your voice or finds it difficult to. If that is the case, you might have to retrain the Assistant with your voice model.

Launch the Google app and tap More > Settings > Voice > Voice Match > Retrain voice model. Follow the prompts and says the commands displayed on your screen to retrain the Google Assistant.

Final Checks

Google Assistant supports devices running the Android 5.0 Lollipop or newer. If none of the above gets the OK Google command to work on your device, you should update its operating system to the latest supported version. Additionally, ensure that you have sufficient space left on your device; Google Assistant requires a minimum of 1GB – 1.5GB of internal storage space to function efficiently. You should also check whether your device’s microphone is blocked or covered with dirt or debris. That could cause the Google Assistant not to detect your voice when you say the ‘OK Google’ or ‘Hey Google’ hotword.
