Qualcomm has simply introduced the 3D Sonic Sensor Gen 2, the newest model of its ultrasonic in-display fingerprint sensor that appears to enhance on the unique mannequin in practically each approach. The brand new model gives a bigger floor space for the sensor and sooner processing to unlock telephones even faster.
The corporate is making a giant leap right here: the brand new Gen 2 mannequin measures 8mm x 8mm, in comparison with the 4mm x 9mm floor space of the first-generation mannequin, for 77 p.c extra floor space. In flip, meaning it’ll be simpler to precisely place your finger on the sensor, and it permits for the sensor to gather extra information with every scan. By combining the bigger sensor with sooner processing, Qualcomm guarantees that scanning a fingerprint to unlock a cellphone will go 50 p.c sooner with the 3D Sonic Sensor Gen 2.
Qualcomm’s first-generation ultrasonic sensor — the 3D Sonic Sensor — made its debut in the Galaxy S10 lineup of phones in 2018. On the time, practically each different in-display reader used an optical scanner, which was mentioned to be slower and fewer dependable than the brand new ultrasonic one.
However the actuality turned out to be the other: the first-generation 3D Sonic Sensor bumped into numerous issues, together with a extremely problematic safety flaw that brought on the readers to unlock telephones with almost any fingerprint when used with some display protectors. (Samsung would later fix the problem with a software program replace.) And the corporate recently issued one other patch for the Galaxy Observe 20 lineup, addressing comparable display protector issues.
The brand new sensor is technically the third under-display ultrasonic fingerprint reader from Qualcomm, following the unique 3D Sonic Sensor and the 3D Sonic Max (launched in 2019) — which was successfully only a a lot bigger model of the first-gen sensor, but it surely lacked any actual velocity enhancements. Whereas the 3D Sonic Sensor Gen 2 doesn’t fairly match the 3D Sonic Max’s sensor (which measured a whopping 20mm x 30mm) in dimension, the velocity enhancements ought to greater than make up for it.
Qualcomm says that the primary telephones to characteristic that new 3D Sonic Sensor Gen 2 must be obtainable in “early 2021.” The corporate doesn’t point out any companions or extra particular timing in its announcement, but it surely’s value noting that Samsung is anticipated to announce its newest Galaxy S21 units on January 14th. Samsung is the most important buyer for Qualcomm’s ultrasonic fingerprint readers to this point, having beforehand used them in its S10, Observe 10, S20, and Observe 20 lineups for the previous two years.
