This feature may be more vulnerable to security than the other screen locks, such as Knock Code, Pattern, PIN, and Password. When a similar voice or your recorded voice is used, the screen may be unlocked.
To use this feature, tap Home > Settings > Lock screen & security > Secure lock settings > Smart Lock, and then use the screen lock method you set to unlock the device. Tap Voice Match > Unlock with Voice Match, and tap ON/OFF, then enter the currently used unlock method again. Note that Swipe is excluded.
You need to unlock the device by using the specified method after failing to unlock the device with voice recognition. See Setting a Screen Lock for details.
