Samsung was the first mainstream smartphone maker to utilize Qualcomm’s 3D ultrasonic fingerprint sensor inside the Galaxy S10. However, after the recent issue concerning the less secure fingerprint sensors inside the Galaxy S10 and Note 10 models, Samsung could be hesitant to use Qualcomm ultrasonic fingerprint sensors in its 2020 models.
The news comes via KoreaTimes which reports that there’s a growing concern among smartphone manufacturers and customers about the security of Qualcomm’s Ultrasonic fingerprint sensors. The report further adds that industry officials had doubts about this technology even before it made it to the market as it ‘exhibited a greater probability of errors’. So the recent issue with Samsung’s devices further spoiled the sensor’s reputation in the market.

According to the industry official, it looks like Qualcomm’s ultrasonic technology has its limits and developers have to be extra careful in designing software for its sensors. On the other hand, the optical sensor based in-display sensors seem to be doing well, with a lot of manufacturers adopting this technology over ultrasonic sensors.
The two technologies differ in the way they read a user’s fingerprint. Optical in-display sensors use optical (light-based) scanners to authenticate the user’s fingerprint while Qualcomm’s sensors use ultrasonic waves.
Given the issues associated with Qualcomm’s ultrasonic in-display fingerprint sensors, it is possible that Samsung ditches it in favor of the traditional optical scanners for its next-generation Galaxy flagships. To recall, Samsung phones like Galaxy S10 and Note 10 were both blacklisted by a number of international banks back when the fingerprint security issue was revealed. Given how smartphones are increasingly being used to make financial transactions, manufacturers like Samsung wouldn’t want to take any risks in terms of security.
Note that Samsung is yet to comment on this matter.
