You can unlock your Galaxy S10 with an in-display fingerprint reader that doesn’t take up space on the phone, thanks to its sensor being built under the screen. This feature is great for those who don’t want to bother with facial recognition. This new reader uses ultrasonic wave technology, which is designed to help the Galaxy S10 actually read the ridges of your fingerprints instead of simply taking a photo with an optical sensor.

Furthermore, this technology works even when the screen is off or on low-power mode. You also don’t have to worry about the reader being unable to recognize your print when your finger is wet. The Galaxy S10 also uses 3D anti-spoofing technology, so you can prevent unwanted people from getting into your phone. This way you can make secure payments, authenticate, and more.
