Unlocking Your Device Automatically

The Smart Lock feature makes unlocking your device easier by letting you set it to unlock

automatically in certain situations. You can keep your device unlocked, for example,

when it’s connected to a Bluetooth® device or when you’re carrying it with you.
To prepare your device to unlock automatically, you first need to perform the following

steps in order:

Make sure you have an active Internet connection, preferably a Wi-Fi connection to limit

data traffic charges.

Make sure all your apps are updated using the Play Store™ application in order to

ensure the Google Play™ services app is updated. Having an up-to-date Google Play™

services app ensures that you can use the latest Smart Lock features.

Bluetooth® watch or a fitness tracker, you can add them as trusted devices and bypass

the added security of the lockscreen 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, such as Bluetooth® keyboards or cases.

As soon as a trusted Bluetooth® device is switched off or moves out of range, your screen

locks and you need your PIN, pattern, or password to unlock it.

To Add a Trusted Bluetooth® Device

Make sure your device is paired and connected to the Bluetooth® device that you

want to add as a trusted device.

2

Find and tap

Settings > Lock screen & security > Smart Lock > Add trusted

device > Bluetooth.

3

Tap a device name to select it from the list of connected devices. Only paired

devices appear in this list.

Depending on the security of your connection, you may need to manually unlock

your device before the trusted device can keep it unlocked.

Making Sure You're Secure when Using Trusted Devices

Different Bluetooth® devices support different Bluetooth® standards and security

capabilities. There's a chance someone could keep your Xperia™ device unlocked by

imitating your Bluetooth® connection, even if your trusted device is no longer nearby.

Your device is not always able to determine whether your connection is secure from

someone trying to imitate it.
When your device can't determine whether you're using a secure connection, you'll get a

notification on your Xperia™ device and may need to manually unlock it before the

trusted device can keep it unlocked.

Bluetooth® connectivity range can vary depending on factors like the model of your device,

the connected Bluetooth® device, and your environment. Depending on these factors,

Bluetooth® connections can work over distances up to 100 meters.

Connecting to Trusted Places

When the Trusted places feature is set up, the lockscreen security on your Xperia™

device gets disabled when you are in a designated trusted location. For this feature to

work, you must have an Internet connection, preferably over Wi-Fi, and allow your device

to use your current location.
To set up trusted places, first make sure that high accuracy location mode or battery-

saving location mode is enabled on your device before you add home or custom

locations.

The exact dimensions of a trusted location are an estimate and may extend beyond the

physical walls of your home or other areas you have added as trusted locations. This feature

can keep your device unlocked within a radius of up to 80 meters. Also be aware that location

signals can be replicated or manipulated. Someone with access to specialized equipment

could unlock your device.

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 On-Body Detection

1

From your Homescreen, tap .

2

Find and tap

Settings > Security > Smart Lock > On-body detection.

3

Drag the slider to the On position, and then tap

Continue.
