Many flagship smartphones use Qualcomm 3D Sonic ultrasonic sensors located under the screens to quickly and reliably scan fingerprints on display, even on wet fingers. However, there is no limit to perfection, so the company introduced the next generation of such scanners.

The first generation Qualcomm 3D Sonic Sensor was ultra-thin at just 0.2mm. This allowed manufacturers to create thin flagship smartphones without sacrificing much battery or other components – the sensor was used, for example, in the Samsung Galaxy S10, Note10, S20, and Note20 series devices.

Now Qualcomm has unveiled the 3D Sonic Sensor Gen 2. This second-generation sensor will be 77% larger: 64mm2 (8 × 8 mm) versus 36 mm2 (4 × 9 mm). Thus, it collects 1.7 times more biometric data. At the same time, its operation speed has increased by 50% – that is, the device will be unlocked even faster.

According to the manufacturer, Qualcomm 3D Sonic Sensor Gen 2 will debut on mobile devices early 2021. In other words, we can well hope that it will be used in the Samsung Galaxy S21 smartphones, the announcement of which is scheduled for January 14 (this has already been rumored).
