If a lock screen is set up with a pattern, PIN, or password, the fingerprint sensor can also be used to unlock the Samsung device. Multiple fingerprints can be added.
This guide shows how to enable fingerprint unlock if a fingerprint has already been registered, but if no fingerprint has been registered yet, the machine will request one.
- Open the Settings
- Tap on Lock screen
- Tap on Screen lock type
- Enter your Lock screen Password/PIN/Pattern
- Enable or disable Fingerprints
- If no fingerprint is registered yet, follow the instructions on the screen
