With the Galaxy S10 series, Samsung introduced ultrasonic in-display fingerprint scanner. It was claimed to be fastest and most secure biometric authentication tool, but earlier this month, an issue cropped up. By applying certain types of screen protectors, one could easily unlock the smartphone, even without registering their fingerprint.

Fingerprint recognition issue detailed

A user Castleford, West Yorks, ordered a cheap screen protector from eBay. Her husband was able successfully able to unlock the phone with his fingerprint. Samsung acknowledged the issue and a fix is reportedly being rolled out.

Now, according to a report on Android Central, Samsung has started rolling out a new update for the Galaxy S10 series and Galaxy Note 10 series devices in South Korea. This update carries a fix for the fingerprint recognition issue.

Samsung, on its support site noted, “unofficial, scratched or dirty screen protectors may cause the fingerprint sensor to malfunction.” However, there is a difference between “malfunction” and “allowing anyone to unlock your phone”

Samsung did explain the problem by saying that the scanner was mistakenly “recognizing 3-dimensional patterns appearing on certain silicone screen protecting cases as users’ fingerprints.” As a temporary solution, the company recommended users to refrain from using low-quality screen protectors. The company also urged users to reregister their fingerprints. Update in other countries is expected in the near future.
