Qualcomm has officially announced a new version of its ultrasonic sub-screen fingerprint scanner, dubbed 3D Sonic Sensor Gen 2.
The new image sensor recognizes fingerprints over a larger area, it also offers faster and more accurate recognition. According to Qualcomm, the new 3D Sonic Sensor Gen 2 measures 8 x 8mm compared to 4 x 9mm for the first generation model. This means that the recognition surface area is increased by 77%. This avoids erroneous touches and also collects more data (1.7x) with each scan. Qualcomm promises that fingerprint scanning to unlock the phone will be 50% faster.
Qualcomm’s first-generation ultrasonic sensor, known as the 3D Sonic Sensor, debuted on the Galaxy S10 flagship smartphone lineup in 2018. At the time, almost every other reader on the display used an optical scanner, which was slower and less accurate.
Renowned insider Ice Universe confirms that the new scanner will be used in the Galaxy S21.
