According to a recent report, all Samsung smartphones that came equipped with an ultrasonic fingerprint reader have a security flaw. Basically, it allows an unregistered fingerprint to unlock the device if you use some third party screen protectors. The issue is currently affecting the Galaxy S10, S10+, S10 5G, Note 10, Note 10+ and Note 10+ 5G. The latter, however, is receiving a new update starting today that, hopefully, will fix this issue once and for all.

This is the second update for the smartphone this month and bears the N976BXXU1ASJ2 serial number. Currently, this update is reaching some users in the UK. Interestingly enough, this update is really lightweight with just 18MB in size. According to the changelog, the update brings improvements to the overall performance of fingerprint’s recognition. However, Samsung failed to specify which kind of improvements the update is bringing to the Galaxy Note 10+ 5G. In the end, it could be just a performance upgrade, rather than the long-waited security fix.
Samsung already promised to bring this fix for all the smartphones affected by the issue. Considering that all of them are premium flagship devices, we believe that the firm needs to put it on priority. The ultrasonic reader messes with the readings when a user is using a certain third-part gel-based screen protector. The scanner will read the dotted pattern of the gel instead of your finger and will unlock the screen by just pressing down with any finger.
