Fingerprint recognition

Fingerprint recognition overview

You must register your fingerprint on your device first before using the fingerprint recognition function.

You can use the fingerprint recognition function in the following cases:

  • To unlock the screen.
  • To view locked contents in QuickMemo+.
  • Confirm a purchase by signing in to an app or identifying yourself with your fingerprint.
    • Your fingerprint can be used by the device for user identification. Very similar fingerprints from different users may be recognized by the fingerprint sensor as the same fingerprint. For added security, set the screen lock using a pattern, PIN or Password.
    • If the device cannot detect your fingerprint, or you forget the value specified for registration, contact the LG Authorized Service Center with your device and ID card.

Precautions for fingerprint recognition

Fingerprint recognition accuracy may decrease due to a number of reasons. To maximize the recognition accuracy, check the following before using the device.

  • Ensure that the fingerprint sensor is not damaged by a metallic object, such as coin or key.
  • When water, dust or other foreign substance is on the fingerprint sensor or your finger, the fingerprint registration or recognition may not work. Clean and dry your finger before using the fingerprint sensor.
  • A fingerprint may not be recognized properly if the surface of your finger has a scar or is not smooth due to being soaked in water
  • If you bend your finger or use the fingertip only, your fingerprint may not be recognized. Make sure that your finger covers the entire surface of the fingerprint sensor.
  • Scan only one finger for each registration. Scanning more than one finger may affect fingerprint registration and recognition.
  • The device may generate static electricity if the surrounding air is dry. If the surrounding air is dry, avoid scanning fingerprints, or touch a metallic object, such as coin or key, to remove static electricity before scanning fingerprints.

Appendix

Anti-Theft Guide

You can set up your device to prevent other people from using it if it’s been reset to factory settings without your permission. For example, if your device is lost, stolen, or wiped, only someone with your Google account or screen lock information can use the device. All you need to make sure your device is protected is:

  • Set a screen lock: If your device is lost or stolen but you have a screen lock set, the device can’t be erased using the Settings menu unless your screen is unlocked.
  • Add your Google account on your device: If your device is wiped but you have your Google account on it, the device can’t finish the setup process until your Google account information is entered again.

After your device is protected, you’ll need to either unlock your screen or enter your Google account password if you need to do a factory reset. This ensures that you or someone you trust is doing the reset.

  • Do not forget your Google account and password you had added to your device prior to performing a factory reset. If you can't provide the account information during the setup process, you won't be able to use the device at all after performing the factory reset.
