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 Gallery or 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. To ensure security, set the screen lock using a Knock Code, pattern, PIN or Password. 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. • The device's Power/Lock key has a fingerprint sensor. Ensure that the Power/Lock key is not damaged by a metallic object, such as coin or key. • When water, dust or other foreign substance is on the Power/Lock key 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 Power/Lock key. Custom-designed Features 23
