Qualcomm's Second-Gen Ultrasonic Fingerprint Sensor is Bigger and Faster
Qualcomm doesn’t wish to miss out on the CES 2021 hype and has immediately introduced its second-gen in-display ultrasonic fingerprint sensor. It is formally referred to as the “3D Sonic Sensor Gen 2” and improves on the unique in each side. The firm guarantees an even bigger floor space and quicker recognition speeds.

As per the official press notice, the second-gen ultrasonic fingerprint sensor measures 8mm x 8mm. This means it’s 77% greater than its predecessor, which measures solely 4mm x 9mm. What does this translate to in actual life? The greater floor space means the sensor will now in a position to learn extra knowledge in a single scan. You may have to spend much less time to register your fingerprints. Also, the larger floor space means extra correct unlocking as you don’t must be very exact about the place you place a finger.


Qualcomm has additionally improved the processing velocity and guarantees as much as 50% quicker unlocking time as in comparison with the first-gen sensor. We have seen the first-gen 3D Sonic sensor baked into the Galaxy S10, Note 10, and S20 sequence. And you will have seen folks complain that the ultrasonic sensor, although safer, just isn’t as quick as optical fingerprint sensors discovered aboard most different Android telephones.

Well, if Samsung bakes the 3D Sonic Sensor Gen 2 within the upcoming Galaxy S21 sequence then we will count on to see the efficiency enhancements later this week. This second-gen ultrasonic fingerprint sensor is the third one from Qualcomm over the previous three years. The first iteration of the 3D Sonic Sensor was launched again in 2018 and baked into the Galaxy S10 sequence. Qualcomm made it greater, referred to as it 3D Sonic Max, in 2019 however there have been no velocity or recognition enhancements. So yeah, fingerprint unlocking velocity could possibly be noticeably quicker on the Galaxy S21 sequence.
