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 make 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.

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.
Connecting to trusted devices
You can designate a connected device as trusted and keep your Xperia™ device
unlocked while connected. If you have a device that you connect to regularly using
Bluetooth® or NFC, for example, a home entertainment system or a fitness tracker,
you can add it as a trusted device and bypass the added security of the lock screen
to save time. This feature is suitable if you’re normally in a relatively secure place
when you use these devices. In some cases, you may still need to manually unlock
your device before a trusted device can be connected.
It is not recommended to add devices that are constantly connected to your device as trusted
devices, for example, Bluetooth® keyboards or cases.
As soon as a trusted device is switched off or moves out of range, your screen locks and you
need your PIN, pattern or password to unlock it.
