You will need to enable the "Smart Lock" feature before you can use it to unlock your phone, in case you have forgotten your unlock method.

Locked out of your device and have not set up the "Smart Lock" method?

If you are locked out of your device and have not set up an unlock method, please bring along your Galaxy device and visit your nearest Samsung Service Center. We will provide the help you need to resolve your problem.

You can set the device to unlock itself and remain unlocked when trusted locations or devices are detected. 

For example, if you have set your home as a trusted location, when you get home your device will detect the location and automatically unlock itself. 

  • This feature will be available to use after you set a screen lock method. 
  • If you do not use your device for four hours or when you turn on the device, you must unlock the screen using the pattern, PIN, or password you set. 

How to set the Smart Lock feature on your mobile device

1. On the Settings screen, tap Lock screen.

2. Tap on Smart Lock

3. Unlock the screen using the preset screen lock method. Select an option and follow the on-screen instructions to complete the setup.

The type of Smart Lock method

  • On-body detection: Keep your device unlocked while it's on you
  • Trusted places: Add location where device should be unlocked
  • Trusted devices: Add device to keep this one unlocked when it's nearby

Note: It is not recommended to use the On-body detection to set as a Smart Lock because this mode is unable to distinguish between the actual owner of the mobile device and a complete stranger.

Note: The user interface may vary or change depending on the device.
