The Galaxy S21 Ultra's ultrasonic fingerprint recognition speed is beyond imagination. In fact, the new sensor beats all-optical fingerprint recognition solutions. The scanner is too fast.

The Samsung Galaxy S21 Ultra uses the latest Qualcomm 3D Sonic Sensor Gen 2 fingerprint scanner, which 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.

The Samsung Galaxy S21 lineup will go on sale on February 5th.
