Qualcomm has announced the next iteration of its ultrasonic in-display fingerprint sensor called the 3D Sonic Sensor Gen 2. The latest version brings improvements as expected in speed and larger surface area for the sensor which means phones take a shorter time to unlock.
Qualcomm’s ultrasonic tech uses sound waves to scan 3D features when users try to unlock phones with their fingerprint; this is different from what optical in-display fingerprint solutions offer. The first generation of the 3D Sonic Sensor made its debut on Samsung’s Galaxy S10 and was also featured on the Note10, S20 and the Note20 lineup. It was flawed and was not as accurate as expected, the first generation of the 3D Sonic Sensor lagged behind other in-display fingerprint readers from OnePlus and Huawei.
Qualcomm promises a 50% faster speed than the first generation in the latest version of its ultrasonic in-display fingerprint reader and a 77% larger surface area. This is a significant improvement on the first-generation with a very small surface area which was difficult to read. In comparison, the first-gen scanner was 4 x 9mm while new second-gen will measure 8 x 8mm which will allow the sensor to pick up 1.7X more biometric information.
According to Qualcomm, the phones with the second-gen 3D Sonic Sensor are expected to come out in “early 2021.” With Samsung’s Unpacked Event slated for January 14th, it will be no surprise if the Galaxy S21 lineup debuts the latest ultrasonic fingerprint readers.
