Have you ever wondered if Google’s voice assistant’s hands-free capabilities extend to unlocking your smartphone? Google Assistant can do many things using voice commands including unlocking your smartphone with Voice Match depending on your Android version.

We’ll explain this nifty trick, as well as whether your Android device allows it, in this guide on how to unlock and lock your phone with your voice.

How to Get Google Assistant on Android

To use Google’s voice unlock feature, you must have Google Assistant on your phone.

Newer Android phones (usually with Android 7.0 Nougat and later) come with Google Assistant pre-installed. When setting up your new phone, all you need to do is enable the feature and grant the relevant Google app permissions. If you’re not sure it’s enabled, open your Google app and tap the button More. choose Settings > Google Assistant to check.

If you have an older version of Android, Google Assistant ships via automatic updates. Any phone with Android Lollipop (5.0) or higher can run the app just download it Google Assistant app from Google Play.

There are several prerequisites that can hinder or delay the update. If your phone is Assistant compatible but you don’t see a prompt to activate it, you’ll need to check a few criteria first.

First, make sure the language you choose for your phone is one of the languages ​​supported by Google Assistant.

If you have the correct language set and you still don’t see Google Assistant, make sure the app Google Play Services You are up to date. Older, less powerful devices not compatible with Google Assistant; You need at least 1GB (Android 5.0) of memory and a screen resolution of 720p.

How to Unlock Your Phone Using Google Assistant Voice

Notes: The smartphone voice unlock feature of Google Assistant only works on certain Android versions: specifically Android 5.0 to Android 7.1.2. Google has removed this feature from Android 8.0 and up.

If you have the right version of Android, unlocking your phone with Google Assistant is as easy as saying “OK Google.” To do this, you’ll need to set up the following:

  • Register a trusted voice model with Google Assistant.
  • Enable voice unlock in Assistant settings.

You can do both by opening Google Assistant and accessing its settings. To do this, tap the icon Drawer blue in the Google Assistant interface. Select button Menu three dots and choose Settings. Under the title Devices, tap your phone. Activate Access with Voice Match and Unlock with Voice Match.

Once activated, you will be asked to train a trusted voice model to unlock your phone. This ensures that Google Assistant will only respond to your voice when the phone is locked.

When you activate voice unlock, the app will ask you to record some phrases. If you want to retrain your voice model for some reason, you’ll find options in the same settings menu below Voice models > Retrain voice models.

You may want to do this if your original recording is at a low volume or in a noisy environment. For security purposes, your phone only stores one trusted voice model at a time. While you can set multiple sound profiles on Google Home, this does not apply to your smartphone.

Voice Unlock Problems You May Face

Unlocking your phone with Google Assistant isn’t always easy, especially if you have other security measures on your lock screen. If your phone requires a fingerprint, pattern, face ID, or PIN, Google Assistant may only be able to wake your phone and turn on the screen, but not bypass the security screen. If so, you will still need to enter a security method.

You can bypass that hurdle by clearing the security screen, but we don’t recommend this. Instead, consider adding a snooze timer to keep your phone from locking immediately after the screen turns off. This means your phone will only lock and require a security method if it is inactive for a certain period of time.

To change this setting, go to Settings > Security & location. Tap the icon Gears next to entry screen lock and select delay below Automatically lock.

In the same menu, you can also set Google Smart Lock. It keeps your phone from locking in trusted locations, when connected to certain Bluetooth devices, and more. You can then wake up your device without needing a PIN or any other security method in that case.

With so many brand-specific variations of Android available, voice unlock isn’t always consistent across devices. Some phones that have a security lock will automatically unlock for trusted voice.

The most troublesome problem with some phones is that voice unlock won’t work unless the screen is on.
