Commercially released less than five months ago, the Galaxy Note 20 and Note 20 Ultra are set to remain Samsung’s latest flagship phones for a few more weeks, so it’s not exactly surprising to see the company still working hard on keeping the two’s software as fresh, zippy, and as secure as possible.
This bug was “privately disclosed” by an unnamed source almost three months back, leading to “false recognition” of the under-display fingerprint scanner on the Note 20 and Note 20 Ultra. While the largest global smartphone vendor doesn’t go into a lot of detail regarding the nature and root cause of the vulnerability or exactly how easy it was for malicious individuals to exploit it prior to this patch, it sure sounds like the aforementioned biometric sensor had trouble dealing with screen protectors of some type.
Since the issue was considered “moderately” severe, we have reason to believe Note 20 and Note 20 Ultra users may have encountered a fairly large number of false positive fingerprint readings in the last few months as well, which is why you should never rely on a single method of protecting your most precious mobile data nowadays.
