iPhones have shipped with facial recognition technology. Face unlock has also been available as a native Android feature for years, but it's not as secure as Apple's Face ID.
Like previous Galaxy S-series models, all devices in the in a Galaxy S23 series device, s will first need to set a PIN, Pattern, or .
Face Unlock Limitations On The Galaxy S23
Once that's done, go to 'Settings,' tap 'Security and privacy,' and then select 'Biometrics.' Now simply tap 'Face recognition' and then enter the PIN, , or pattern to confirm identity. Once that's done, hit 'Continue' and then hold the phone 8-20 inches away in a way that the face is positioned inside the on-screen circle. Hold the position until the progress bar reaches 100 percent and follow on-screen instructions to the face on the device. Once the face is ed, s can unlock their phone just by looking at it.
While face unlock offers convenience, there are a few things that s need to be aware of. Unlike Face ID in iPhones that uses dedicated hardware like a dot projector, a flood illuminator, and an infrared camera, the facial recognition technology in the Galaxy S23 (and most Android phones) only uses the front-facing camera. In additional to facial recognition, all Galaxy S23 series devices also have an ultrasonic in-display fingerprint scanner that uses specialized hardware placed underneath the screen to identify the legitimate owner, enabling them to unlock the device, access compatible apps, authorize transactions, and more.
The lack of dedicated face unlock hardware makes the facial recognition technology in the Galaxy S23 series devices relatively less secure, meaning it can only be used to unlock the device and not to access banking apps and other high-security features. To approve payments in apps or do most other things that require biometric authentication, s will still have to use the fingerprint scanner in the Galaxy S23, as it's far more secure than the software-based face recognition.
Using biometric security isn’t a requirement, though. Galaxy S23 owners always have the option to choose a different method for protecting the contents of their phone. Samsung allows smartphone owners to unlock their phones by PIN, pattern, and s. For the first option, s must create a unique PIN containing 4-16 numbers that they’ll have to punch in every time they unlock the phone. Similarly, they can create a of 4-16 characters. The difference between these two is that the latter must contain at least one letter, and can also include symbols. With the pattern security method, s must draw a shape on the screen by connecting at least four dots in the provided grid.
