Yes, Samsung A33 5G, A53 5G, and A73 5G have face unlock and fingerprint sensor. You will be prompted to set up both security measure features the first time you turn on your device.
The face unlock implementation on these devices is not as secure as the one on the iPhones. The Galaxy A73 5G, A33 5G, and A53 5G are equipped with an optical in-display fingerprint sensor.
Fingerprint is one of the most dependable forms of biometric security measures put in place for smartphone users because it is unique to an individual.
It works the same way as a password, the first time that you register a fingerprint, it stores it in a database and when you come back again, it compares what you are inputting to what it already has in its database.
If you skip the registration of fingerprint while setting up your smartphone for the first time, you can always go to the Settings app to do it later. You can also add more fingers.
Managing your fingerprint is equally as easy. Go to Settings -> Security and privacy -> Biometrics -> Fingerprints -> Enter password/draw pattern -> Place different sides of your finger on the fingerprint sensor -> Done to complete the process.
To add, remove, rename, and essentially manage your fingerprint, follow the above steps up to where you draw your pattern or enter the lock screen credentials and tap on Add fingerprint to add a new fingerprint or tap on an existing fingerprint to rename or remove it.
Samsung A33 5G, A53 5G, and A73 5G have one of the best implementations of an optical in-display fingerprint sensor on a mid-range smartphone. It is fast and doesn’t take the hustle to use it.
The setup process is equally easy and similar for Face Unlock on all three devices.
