    The Smart Lock feature unlocks your device automatically in certain situations. You can set your device to unlock, for example, when it’s connected to a Bluetooth® device, when it recognizes your face or voice or when you’re carrying it with you.

    To prepare your device to unlock automatically, perform the following steps:

    • Make sure you have an active Internet connection, preferably a Wi-Fi® connection to limit data traffic charges.
    • Make sure that all your apps are updated using the Play Store™ application in order to ensure that the Google Play™ services app is updated. Having an up-to-date Google Play™ services app ensures that you can use the latest Smart Lock features.
    • Enable Smart Lock.
    • Set when you want your device to unlock automatically by selecting a Smart Lock type. 

    Smart Lock types

    • On-body detection - keep your device unlocked when you're carrying the device with you. 
    • Trusted places - keep your device unlocked when you're in a trusted location.
    • Trusted devices - keep your device unlocked when a trusted Bluetooth device is connected. 
    • Trusted face - let your device unlock when it recognises your face.
    • Voice Match - allows you to access and interact with Google Assistant even if your screen is locked. 

    To enable Smart Lock

    1. Make sure that you've set a pattern, PIN or password for your screen lock.
    2. Find and tap Settings > Lock screen & security > Advanced > Trust agents.
    3. Drag the slider beside Smart Lock (Google) to the right.
    4. Tap the back arrow next to Trust agents

    Note 1: The Smart Lock feature may not be available in every market, country or region. Keep in mind that Smart Lock as a security feature is less secure than a pattern, PIN, or password. 
    Note 2: The Smart Lock feature is developed by Google™ and the exact functionality may change over time due to updates from Google.
