Samsung pushing update for Galaxy S10 and Note 10 devices that fixes fingerprint security issue


If you’re rocking a Galaxy S10 or Note 10 device, there’s an important update coming your way from Samsung.

Samsung is now sending out a biometrics update to the Galaxy S10, S10+, S10 5G, Note 10, and Note 10+. It’s meant to patch a security issue discovered recently that allows any fingerprint to unlock your phone if you’re using certain third-party silicone screen protectors. Samsung explains that these screen protectors have a textured surface on the inside that may be recognized by the phone as a fingerprint.

This update is being sent to all Galaxy S10, S10+, S10 5G, Note 10, and Note 10+ phones that have fingerprint data registered on the device. A Samsung note spotted by Android Police says that this update is rolling out gradually and will be sent within 24 hours, so if you haven’t gotten his update yet, it should appear soon.


TmoNews reader Daryl got this update today on their T-Mobile Galaxy S10. Several users on Reddit say they’ve gotten it as well, including one person with a T-Mobile Galaxy S10+.

The in-display fingerprint reader on Samsung’s Galaxy S10 and Note 10 devices isn’t the only way to secure these phones, but lots of folks are probably using it for its convenience. This is a pretty serious security issue for Samsung, as personal data like photos and banking info can be stored behind a fingerprint sensor. If you’ve got a Galaxy S10 or Note 10 device, be on the lookout for this update and install it as soon as it arrives.

Thanks, Daryl!

    My BoA app has already disabled fingerprint auth on my Note10+ because of this.

      Oh Joy,. It’s crazy how blown out of proportion this micro-issue got. 99%. Of the articles in my feed were fear mongering national enquire level click-bait. The articles made it sound like it was an exploitable bypass not a security issue of don’t register your fingerprints with a PET screen protector (sidenote Note10 screens are scratch magnets – did they switch to a new Gorilla glass with the 10?)

      Actually prefer the reader on the back of my Note 9 – it’s easier to use one handed without phone juggling – 10s in screen reader is a little prissy reminds me of the Galaxy S5 reader that was hit or miss. The S5 front reader was almost a two handed affair with a front reader.
