in the security settings of the Samsung device, the "Faster recognition" function is enabled for face recognition. this improves the speed of recognition but reduces security. this means that face recognition can also incorrectly be performed by a photo or video of the person. this can happen even if the function is disabled, but the risk is much lower.
- Open the Settings
- Tap on Biometrics and security
- Tap on Face recognition
- Enter PIN/Pattern/Password
- Enable or disable Faster recognition
