Samsung's Galaxy S10 , announced in February 2019, is equipped with an ultrasonic scanner that can read fingerprints on the display. This is a function of Qualcomm's 3D Sonic Sensor, and the fingerprint recognition area was approximately 9mm x 4mm.
However, a typical fingertip is approximately 14mm x 14mm, and only one part of the fingertip can be scanned by the 3D Sonic Sensor. In addition, it was pointed out that the Galaxy S10 fingerprint sensor has poor fingerprint recognition accuracy and takes time to unlock. It was also reported that Galaxy S10 had a bug that could unlock anyone's fingerprints using some silicone covers and screen protection films.

The fingerprint recognition area of 3D Sonic Max, the second-generation 3D sensor announced this time, has been expanded to 30 mm x 20 mm, approximately 17 times the size of 3D Sonic Sensor. According to Alex Katodian, general manager of Qualcomm's Mobile Division, 3D Sonic Max is the “largest fingerprint sensor in the world” at the time of writing.
In addition to the increased sensor size, more parts of the finger can be mapped, and two fingerprints can be recognized simultaneously by one sensor, so the accuracy of fingerprint recognition is 20% of the previous generation. Katowian explains that it doubles. However, 3D Sonic Max takes about the same time as 3D Sonic Sensor to unlock the smartphone.
“There are mobile phone manufacturers who are interested in this 3D Sonic Max at the moment, but we ca n’t tell who they are. It ’s expected to be announced in 2020.” I told you.
About this, Taiwan Media Economic Daily reports that `` Apple is planning to introduce Qualcomm's in-screen fingerprint recognition sensor to the next generation iPhone '', but technical media CNET asked Apple to comment, answer It seems that there was not.
