Fingerprint sensors are an expected feature of any smartphone these days, and in the case of the Galaxy S21 FE, it's something Samsung ensured to fully realize. Many components are critical to a good smartphone experience. Folks want to be sure they have a quality display, good performance, long battery life, and reliable cameras. If a phone doesn't have those things, it immediately becomes a much harder sell than one that does.
Among those, a fingerprint sensor is every bit as important. Not only does it make a phone more convenient to use, but it also adds a huge layer of security. Want to quickly unlock your phone's lock screen, log into a banking app, or view passwords in a password manager? Fingerprint sensors speed up the process of all these things without sacrificing their safety. No matter who you are, it's one of those features that's almost impossible to live without.
Thankfully, this is something Samsung was fully aware of when designing the S21 FE. No matter which configuration you choose or which retailer you buy it from, all models of the Galaxy S21 FE come with a fingerprint sensor. This has been a standard practice of Samsung flagships for a few years now. Even the company's mid and lower-end devices now have fingerprint sensors — something that was unheard of just a few short years ago. If you're in the market for a new phone and need it to have a fingerprint sensor, the S21 FE is a device that fits the bill.
Tips For Using The S21 FE's Fingerprint Sensor
As you get ready to start using the S21 FE's fingerprint sensor, there are a few tips to keep in mind for doing so. Similar to the S21 and S20 FE, the Galaxy S21 FE's fingerprint sensor is an optical one that resides underneath the display. On the lock screen and when logging into certain apps, a fingerprint icon appears towards the bottom of the display where the sensor is. Place your finger on the fingerprint icon, and the lock screen or app should unlock in an instant.
If you find that the fingerprint sensor isn't working as quickly/reliably as you'd like, a good tip is to register the same finger multiple times. Registering the same finger two or three times gives the S21 FE much more data to work with — and will likely get rid of failed scans that can be oh-so annoying. To do this, follow these steps: Open the Settings app, tap 'Biometrics and security,' tap 'Fingerprints,' tap 'Add fingerprint,' and follow the on-screen instructions to re-register your finger. Once that's done, the Samsung Galaxy S21 FE's fingerprint sensor should work better than ever.
