Keep your device unlocked when it's on you

You can keep your device unlocked when you're carrying it in your hand, pocket or bag.

Turn on-body detection on or off

  1. In the Smart Lock menu, tap On-body detection.
  2. Turn Smart Lock On-body detection on or off.

Use on-body detection

  • After you unlock your device, it stays unlocked as long as it senses that it’s on your body. After you put down your device, such as if you set it on a table, your device can take up to one minute to automatically lock.
  • On some devices, on-body detection learns the pattern of your walk. If it detects a walk that's very different, it could lock your phone. If your phone locks after walking, unlock the phone and it will learn the changes in your walk.
  • After you get into a car, bus, train or other vehicle, your device can take 5-10 minutes to lock.
    Important: When you're on an aeroplane or boat, your device could not lock automatically. Make sure to lock manually if needed. Learn how.

Note: Your device stores accelerometer data about the pattern of your walk to help determine when you're carrying your device. When you turn off on-body detection, your device deletes this data.

Bluetooth connectivity range can vary. Range depends on factors like your device model, Bluetooth device and current environment. Bluetooth connectivity can be up to 100 metres. If someone takes your phone while it's near your trusted device, and if your trusted device has unlocked it, that person could access your phone.

Set up, improve or remove a trusted face

You can have your device unlock when it recognises your face. After you set a trusted face, every time you turn on your device, it'll look for your face and unlock if it recognises you.
