Naturally, Google needs access to your personal data and device permissions to enable such complex and robust features. The Assistant collects and stores data from your other devices, site and app activity, and contacts to provide functionality. In addition, it always listens in the background for the voice trigger, so it also needs audio and voice permissions. The constant pinging drains the battery, so disabling Assistant can help save battery.
It also raises obvious privacy concerns; you might be put off by the intrusive data collection or near-universal access that the Google Assistant app requires. Some users don’t even use the Assistant. In those cases, we recommend disabling the Google Assistant.
Google Assistant comes with the Google app and can be accessed by saying “Hey Google”. But it only recognizes your voice because the Assistant is trained on your voice profile. Once disabled, the Assistant will no longer respond to the trigger.
1. Open the Google app (search “Google” in the app drawer if you can’t find it).
2. Tap your profile icon and then tap Settings.
3. Tap Google Assistant on the Settings page.
4. Scroll down to General and disable Google Assistant.
The other way to turn it off is also easy enough, but the UI layout and labels vary by Android phone brand.
1. Go to Settings, Apps and Default Apps. Or search “default apps” in the Settings search bar.
2. Tap Default assistant and select None.
