The fingerprint sensor has been one of the biggest changes we’ve seen in the smartphone industry globally. Firms like Samsung already implement advanced ultrasonic models under the screen in mobile phones that we can buy in Spain.
However, despite the popularization of this type of sensors, there are still many who prefer to have one on the back or on the side of the terminal, because they are faster and more reliable.
This is what Qualcomm wants to change with its new fingerprint sensor under the screen, the Qualcomm 3D Sonic Sensor 2.
A larger, faster fingerprint sensor that captures more data
This second generation of ultrasonic fingerprint sensors, the first one released in 2018, promises a more effective use of this technology by providing a 77% larger surface area and up to 50% faster fingerprint detection. We went from 4 x 9 mm to 8 x 8 mm.
In addition, the increased precision makes it possible to capture more data from our fingers so that security is also increased.
These types of sensors have been used especially in Samsung’s high-end models, and allow the terminal to be used with wet hands, for example. Of course, unlike optical sensors, which we usually see in the models of Chinese manufacturers, the speed was lower.
Qualcomm aims to catch up with this new generation and it is possible that the new Samsung Galaxy S21 are responsible for releasing the new technology. The company has pointed out that we will see the first models with these new sensors in the first quarter of 2021 and taking into account that the Galaxy S have used them for some years, it is very possible that in two days we can see the behavior of the new ones.

The largest and fastest entry: this is the new Qualcomm 3D Sonic Sensor 2 fingerprint sensor appears first in The Free Android.
