Qualcomm's new sensor released

Qualcomm recently released its second-generation ultrasonic under-screen fingerprint reader 3D Sonic Sensor Gen 2. The scanning area of ​​this scanner is 1.7 times larger than before, and the scanning speed is 50% faster. It crushes the original model in almost all aspects.

Qualcomm’s first-generation 3D acoustic wave sensor was launched in 2018. This under-screen fingerprint sensor solution uses ultrasound for biometric authentication, making it safer and more accurate than optical sensors. Subsequently, many flagship devices, including Samsung S10 series, Note10 series, S20 series and Note20 series, used the 3D acoustic wave sensor for biometric identification.

Compared with the recently released second-generation ultrasonic under-screen fingerprint reader, its surface area is 64 square millimeters, while the initial representative area is only 36 square millimeters, and the surface area has increased by 77%. In turn, this means that it is easier to accurately place your finger on the sensor and allows the sensor to collect more data with each scan. Qualcomm promises that by combining larger sensors with faster processing speeds, scanning fingerprints to unlock mobile phones will be 50% faster than the first generation.

In terms of compatible mobile phones, Qualcomm said that the first Android flagship smartphones with the new second-generation ultrasonic fingerprint reader should be available in early 2021. What’s interesting is that Samsung will release the latest Galaxy S21 on January 14. Equipment, so there is a high probability that Samsung will be the first to use this technology.
