In-display Ultrasonic Fingerprint Scanner
Fingerprint Scanner has moved from the back to the front, creating a revolutionary, on-screen sensor. Using ultrasonic pulses, it detects the 3D ridges and valleys of your fingerprint. It’s secure and convenient — even allowing you to unlock, drag, and hold to open the app you want.
Infinity-O Display with Dynamic AMOLED
Completely redesigned to remove interruptions from your view. No notch, no distractions. Precise laser cutting, on-screen security and a Dynamic AMOLED make the Display the most innovative Galaxy screen yet.
