iQOO released the first iQOO 8 Pro that supports ultrasonic 3D wide-area fingerprint unlocking. Today, it is reported that the Samsung Galaxy S23 Ultra will also use an ultrasonic 3D wide-area fingerprint sensor. According to Alvin, there are rumors that the Samsung Galaxy S23 Ultra will use Qualcomm’s ultrasonic 3D wide area (3D Sonic Max) fingerprint scanning technology, which is the same as the ultrasonic 3D wide area fingerprint sensor used by Vivo X80 Pro, iQOO 9 Pro and other mobile phones.

The S23 Ultra will also provide a larger fingerprint recognition area and faster unlocking speed. Qualcomm’s official introduction to the 3D Sonic Max ultrasonic fingerprint sensor is:
The Qualcomm 3D Sonic Max ultrasonic fingerprint sensor utilizes evolving ultrasonic technology to read 3D features such as ridges, grooves, and pores of the user’s finger, thereby constructing a very accurate fingerprint image, enabling mobile terminals to provide high-performance fingerprint security solutions. The Qualcomm 3D Sonic Max ultrasonic fingerprint sensor can penetrate surfaces such as glass and metal for accurate fingerprint scanning, even when the finger is wet, for example.
Thanks to the large recognition area, the Qualcomm 3D Sonic Max ultrasonic fingerprint sensor also supports reading two fingerprints at the same time, which not only further improves the security of applications such as payment, but also fully upgrades the privacy of the mobile phone. For example, parents can set certain apps to be dual-fingerprint unlocked, so that children must have parental involvement to unlock those apps.
Previously, Samsung used ultrasonic under-screen fingerprints on the Galaxy S22 Ultra. As to why it did not use the ultrasonic 3D wide-area fingerprint unlocking solution, sources believed that it was because of cost issues, and it speculated that Samsung used Qualcomm processing on all Galaxy S23 series phones because Qualcomm promised a few extras, including an ultrasonic 3D wide-area fingerprint sensor at a lower price.
