Qualcomm has announced the 3D Sonic Sensor Gen 2. This is the second generation of its ultrasonic fingerprint Qualcomm scanner for smartphones.
The new Qualcomm fingerprint scanner seems to improve almost everything on the original implementation. The new version has a larger area on which you can put your finger and has a faster processor, so that phones (and probably also tablets) are unlocked faster.
Second generation Qualcomm scanner
The leap from the original and the new model is big. Where the area used to be 4 by 9 millimeters, this is 8 by 8 millimeters with the second generation. This makes the area 77 percent larger. For users, this means that you have more space to put your finger on, while the fingerprint scanner can scan more data. In addition, the faster processor must ensure that phones are unlocked up to fifty percent faster.
At the time, the first generation of the Qualcomm fingerprint scanner was used on Samsung Galaxy S10 smartphones in 2018. At the time, it was claimed to be a faster and safer alternative to optical scanners. That idea was soon changed, when it turned out that there were errors in the first generation 3D Sonic Sensor. This allowed users to unlock phones with every finger; whether they were committed or not. Samsung later released a patch for this itself. Recently other problems surfaced with the scanners: the Note 20 line got an update, because the screen protectors caused problems.
In fact, the Gen 2 is the third variant of Qualcomm’s ultrasonic fingerprint scanner as the company also released the Max in 2019. That was not a real successor. There were no improvements in speed, but the scanning area was enormous: 20 by 30 millimeters.
The first phones to get the new Gen 2 scanner are expected in early 2021, the manufacturer said. Samsung intends to present the latest Galaxy on January 14 . This is said to be the first smartphone to receive the new sensor.
