Keeping Your Device Unlocked while You’re Carrying It
Using the On-body detection feature, you can keep your device unlocked while you're
carrying it in your hand or in a pocket or bag. The accelerometer in your device keeps
your device unlocked while it senses that it's being carried. The device locks when the
accelerometer detects that the device has been put down.
When you use the On-body detection feature, you need to be aware of the following
behaviors:
•Any time you put your device down and it senses that it's no longer being carried, it
locks automatically.
•The device can take up to one minute to lock.
•After you get into a car, bus, train, or other land vehicle, your device can take between 5
and 10 minutes to lock.
•Note that when you get on an airplane or a boat (or another non-land-based vehicle),
your device may not lock automatically, so be sure to lock it manually if needed.
•When you pick up your device again or get out of the vehicle, just unlock it once and
your device then stays unlocked for as long as you have it on you.
The On-body detection feature can't distinguish whose body is connected. If you give your
device to someone else while it's unlocked using On-body detection, your device may stay
unlocked for the other user. Keep in mind that On-body detection as a security feature is less
secure than a pattern, PIN, or password.
To Enable or Disable On-Body Detection
1From your Home screen, tap .
2Find and tap Settings > Lock screen & security > Smart Lock > On-body
detection.
3Tap the slider to enable the function, then tap CONTINUE. To disable the function,
tap the slider beside On.
