Undoubtedly Qualcomm is one of the protagonists of the week in the field of mobile devices, as it has just presented its new Snapdragon 865 and Snapdragon 765 processors for the first half of 2020 and also a new generation of its fingerprint sensor. ultrasonic that greatly improves its detection ability .

The arrival of sensors that hide underneath the screen was an innovation in the market in the last year, although it could not avoid some performance problems that users raised. Thus, the next Qualcomm 3D Sonic Max will include a size up to 17 times larger that will allow it to detect up to two fingerprints at the same time for the first time.

Qualcomm 3D Sonic Max Features: Qualcomm prepares ultrasonic sensor that reads two fingerprints simultaneously

Features announced for the Qualcomm 3D Sonic Max

Some of the flaws found in the first generation of this type of sensor included errors when detecting fingerprints according to their positioning, as well as a slower recognition speed than expected and even aesthetic details such as gap effects on the screen. in some types of screen protectors used. All this promises to be solved for this new installment.

The so-called Qualcomm 3D Sonic Max will have official dimensions of 20 mm x 30 mm , which means a x17 increase compared to the size of the previous ultrasonic sensor (4 mm x 9 mm). Thus, any user will not have to worry about placing the index finger in an exact position and orientation as is happening today for the phone to unlock.

Likewise, the Chinese brand indicates that the recognition time should be around the same figures as in the current fingerprint sensor, although the advantage of being able to access with the detection of two fingerprints instead of a single one would add a new layer of security. / privacy for those who want it.

At the moment there is only confirmation that its implementation in the market will begin in 2020 , but there are still no exact dates, nor are there models or manufacturers that have already indicated its use. Surely its debut is in some of the main high-end released during the first semester.
