Android How to Turn On/Off On-body detection (Smart Lock)

With the On-body detection feature, the Android smartphone can remain unlocked while it is being carried.
The position sensor detects whether the device is currently being held in the hand or whether it is in a bag. During this time, the device remains unlocked if the on-body detection feature is enabled.

Note: The Android device cannot detect who is holding the device, so in case o theft, for example, an unauthorized person may have access to the device.
