A story emerged last week that the Galaxy S10 fingerprint can be unlocked by an unregistered fingerprint when a sub-standard screen protector was attached. The story rattled the headlines when it emerged last week. Apparently, the issue also affected the Galaxy Note 10 series.
Samsung promised to push a fix for the issue soon and that is already happening. The update is said to be hitting Galaxy S10 and Note 10 units in South Korea. We expect a global rollout to happen pretty soon.

The software flaw was first reported by a British woman whose Galaxy S10 unit was successfully unlocked by her husband’s thumbprint after fixing a cheap screen protector on the device. The lady had bought a £2.70 gel screen protector on eBay and then noticed her left thumbprint, which was not registered could also unlock the phone. Both of her husband’s thumbs could also unlock the phone. The same scenario played out when the screen protector was added to another relative’s phone which we believe is also a Galaxy S10.
The scanner sends ultrasounds to detect 3D ridges of fingerprints in order to recognise users. Samsung explained the problem by noting that the ultrasonic fingerprint was mistakenly “recognizing 3-dimensional patterns appearing on certain silicone screen protecting cases as users’ fingerprints.”
