Galaxy S21 Tip: Learn Biometric security [Samsung Android 12/One UI 4]
Samsung One UI 4.0 is now available for the Galaxy S21 series (as Beta testing activity) in select countries, which is based on Google’s Andriod 12 operating system. The beta program allows users to experience the upcoming OS ahead of the stable launch.
With One UI 4 Beta 2, Samsung has made various adjustments to the user interface and functions. In addition to new features, it also enhances the security and privacy of smartphones. So, in this article, we will discuss how you can enable biometric security on the Galaxy S21 smartphones.
What is Biometric security?
Biometric security provides a more convenient but less secure device confirmation method. Under the hierarchical authentication model, primary authentication (that is, patterns based on knowledge factors, such as PINs, patterns, and passwords) provides the highest level of security. Biometrics is the second layer of identity verification, providing a balance between convenience and security.
Biometric security includes:
- Face recognition
- Fingerprint scanner
