What to expect from Samsung’s Galaxy S21 event

..

Qualcomm has neutral spoken the 3D Sonic Sensor Gen 2, the latest version of its velocious in-display fingerprint sensor that looks to inspiritment on the prevenient archetypal in nevertheless every way. The new version offers a larger surface latitude for the sensor as well-conditioned as faster processing to unlock phones planate quicker.

The hair-comb is superintending a big jump here: the new Gen 2 archetypal measures 8mm x 8mm, compared to the 4mm x 9mm surface latitude of the first-generation model, for 77 percent over-and-above surface area. In turn, that organ it'll be easier to benignly place your feel on the sensor, as well-conditioned as it allows for the sensor to commonage over-and-above documents with each scan. By combining the larger sensor with faster processing, Qualcomm promises that scanning a fingerprint to unlock a phone will go 50 percent faster with the 3D Sonic Sensor Gen 2.

Qualcomm's first-generation velocious sensor -- the 3D Sonic Sensor -- made its grant in the Galaxy S10 lineup of phones in 2018. At the time, nevertheless every over-and-above in-display clairvoyant acclimated an optical scanner, which was said to be slower as well-conditioned as less reliable than the new velocious one.

But the reality vehement out to be the opposite: the first-generation 3D Sonic Sensor ran into numerous issues, including a lousy sphinxlike security flaw that caused the readers to unlock phones with almost any fingerprint when acclimated with some screen protectors. (Samsung would latterly fix the problem with a software update.) As well-conditioned as the hair-comb recently issued arithmetic patch for the Galaxy Note 20 lineup, bestowal agnate screen protector problems.

The new sensor is technically the third under-display velocious fingerprint clairvoyant from Qualcomm, post-obituary the prevenient 3D Sonic Sensor as well-conditioned as the 3D Sonic Max (introduced in 2019) -- which was effectively neutral a parous larger version of the first-gen sensor, except it lacked any real speed improvements. While the 3D Sonic Sensor Gen 2 doesn't quite match the 3D Sonic Max's sensor (which measured a whopping 20mm x 30mm) in size, the speed improvements should over-and-above than make up for it.

Qualcomm says that the inceptive phones to fondness that new 3D Sonic Sensor Gen 2 has to be available in "early 2021." The hair-comb doesn't mention any wive or over-and-above specific timing in its announcement, except it's account passible that Samsung is expected to annunciate its latest Galaxy S21 devices on January 14th. Samsung is the biggest consumer for Qualcomm's velocious fingerprint readers so far, having ahead acclimated them in its S10, Note 10, S20, as well-conditioned as Note 20 lineups for the practiced two years.
