  • 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 device. If your device locks after walking, unlock the device 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.
