Do you find yourself unlocked countless times a day? Typing or unlocking a PIN with your fingerprint can be tedious, no matter how many times you have to do it. Fortunately, Android offers a Smart Lock device for devices running Lollipop or later.

With Smart Lock, you can select situations where your phone will be unlocked for a long time. For example, Trusted location settings keep your phone unlocked at home.

Find Smart Lock settings

1. Open Settings -> Security or Lock Screen and Security.

2. Select Secure Lock Settings.

3. Enter your password, unlock a pattern, PIN, or use a fingerprint.

4. Select Smart Lock.


5. The Smart Lock options appear.


Now that you know where to find it, let’s take a closer look at the different Smart Lock options.

Perception in the body

This Smart Lock setting is the easiest way to configure. It uses your phone’s sensors to detect if you are carrying it with you. One problem with detection is that when you give an unlocked phone to someone else, they may remain unlocked if they move with them. However, some phones learn to walk and lock for everyone but you. Another problem arises if you get in a vehicle. It can take up to ten minutes to lock your phone.

This activates body recognition.

1. In the Android Smart Lock menu, tap “Body Detection”.

2. Activate body recognition.

Trusted places

When you turn on Trusted Locations, your phone determines the geographic boundaries of its mapping software to determine if you are at home, at work, or in another location where you feel comfortable keeping your phone unlocked. When this option is enabled, you do not need to open it as long as your phone is connected to the Internet and location services.

Before you can use Trusted locations, make sure that the location is turned on. If you don’t know how to do it:

1. Tap “Settings”.

2. Find the Location section under Connections.

3. Tap Mode or location, and then select one of three options: High Resolution, Battery Saver, or Device Only.

Once the location is activated, you can start using trusted places.

1. In the Smart Lock menu, tap Trusted locations.

2. Tap Home, and then activate this location.

3. Tap Add trusted location to add another location. The map opens for your current location.

4. To search for another location, press Search, type the name or address of the trusted location, and then press OK.

The face of trust

The face recognition found in Smart Lock is not as secure as the Apple face ID, which requires special equipment. A picture of you can deceive him. It’s not on all phones, but if you have, Trusted Face is one of the nicest Smart Lock options.

Once you’ve set a trusted face, your phone’s front camera will search for your face and open when it recognizes you.

Here’s how to build a trust face:

1. In the Smart Lock menu, tap Trusted Faces.

2. Tap Configure and follow the onscreen instructions.

3. When the phone searches for your face, the Trusted face icon appears.

In some cases, your phone may have difficulty distinguishing your face from someone else’s face. If you encounter this problem, click “Improve facial fit” and follow the instructions.

Trusted voice

Voice Match recognizes the sound of your voice and sound pattern and unlocks your phone without touching it. To use this Smart Lock option, set up speech recognition options and enable voice connections.

1. In the Smart Lock settings menu, tap Voice Match or go to Settings -> Google -> Search -> Voice -> Voice Match.

2. Activate the voice command “OK, Google” and the ability to unlock your phone.

3. If this does not work well, select “Create sound template” to improve it.

Trusted devices

The last way to use Smart Lock on your Android device is to pair Trusted Devices. It keeps your phone locked whenever it is close to other reliable devices, such as a smartwatch. The device unlocks your phone automatically every time it connects.


However, this option has some limitations. If the phone decides that the connection is not secure, Trusted devices will fail. The area can also be a problem. Others can use your phone up to 100 meters from a trusted device!

To use trusted devices to unlock your phone:

1. Open the Smart Lock menu.

2. Tap Trusted devices.

3. Tap Add trusted device and select one of your trusted devices to unlock your phone.

Not all Android devices have all of these options, but the only one missing from the old Galaxy 6 is Trusted Face. If you’re tired of typing in your PIN all the time while sitting at home, at least one of these options may work for you.
