3D Sonic Max, the second generation of the ultrasonic in-display fingerprint sensor can fix the issues of the original 3D Sonic Sensor, and is 17 times bigger. The 3D Sonic Max being much bigger than the previous one is capable of reading two fingerprints at same time for additional authentication. The previous ultrasonic reader assured enhanced reliability and security among optical in-display fingerprint readers.
Samsung Galaxy S10 used the 3D Sonic Sensors and faced a lot of issues such as wrong or inaccurate fingerprint reading, slow speeds and that the sensor can only be read by a few types of fingerprint protectors, which was only fixed by October. The company promises that the 3D Sonic sensor will solve every issue due to being improved and larger than the previous one that measured 4mm x 9mm. The latest sensor measures 20mm x 30mm, or is 17 times larger. Qualcomm solved the problem by adding a bigger sensor for quick and easy fingerprint reading.
Alex Katouzian, SVP and general manager of mobile at Qualcomm noted, "The new 3D Sonic Max should avoid the screen protector problems by capturing a clearer complete fingerprint when reading due to the larger scanner size. The option to require two simultaneous fingerprints to scan together also should help increase security options. One thing that won’t change, though, is the speed. Scanning a fingerprint will take roughly the same amount of time with the new sensor as it did with the old one.”
Qualcomm's new 3D Sonic Max will solve all authentic problems than the old one and the fact that which all companies will use the latest 3D Sonic Max for their devices could only be known in 2020. MacRumors reports, Apple to use Qualcomm’s in-display fingerprint technology in their iPhone as early as next year.
