Smart Lock, Face Detection or even the fingerprint sensor pose a certain security risk, and these unlock methods can be temporarily overridden by an additional button, requiring the entry of the password, pattern or PIN.
The button is displayed on the Samsung device after activation in the power on/off menu.
- Open the Settings
- Tap on Lock screen
- Tap on Secure lock settings
