Ice notes that the area of Galaxy S20’s fingerprint module is 36mm². In contrast, the Galaxy S21 will likely have a 64mm² fingerprint scanner, which would make it 1.77 times bigger.
The ultrasonic fingerprint sensor of Galaxy S21 is 8×8=64mm, which is 1.77 times higher than the previous generation, and the unlocking speed is doubled. You don’t even need to press it, just tap to unlock.

The leaker also says that the next generation of the ultrasonic fingerprint module is twice as fast as the current one, and a tap would be enough to unlock the phone.
It doesn’t look like the Galaxy S21 will employ Qualcomm’s 3D Sonic Max technology
The Galaxy S10 and Note 10 were blacklisted by some bank apps after it emerged that anyone could unlock them using flexible gel screen protectors.
While that doesn’t seem to be the case any longer, it does appear that Samsung has parted ways with Qualcomm’s fingerprint technology.
Either way, it’s still great news that Samsung has finally decided to retire its current fingerprint technology.
