Samsung to fix major flagship fingerprint flaw with imminent patch
June 15, 2025
It emerged earlier this week that the in-display fingerprint sensor onSamsung’s Galaxy S10had amajor security flaw. The bug, which has appeared on theGalaxy Note 10series too, allows someone with an unregistered fingerprint to unlock the phone.
According toReutersandThe Sun, the flaw came about after a British user applied a third-party screen protector to herGalaxy S10. Her husband was then able to unlock her device, even though his fingerprints weren’t registered.
Now,Samsunghas issued a statement, saying that the phones’ ultrasonic fingerprint scanners were recognizing three-dimensional patterns appearing on some “silicone screen protecting cases” as fingerprints belonging to the device owner.
“To prevent any further issues, we advise that Galaxy Note 10/10 Plus and S10/S10 Plus/S10 5G users who use such covers to remove the cover, delete all previous fingerprints and newly register their fingerprints,” the company noted in anofficial post.
Samsung has also called on people using screen protectors to refrain from using said protectors in conjunction with the fingerprint functionality until a software patch has been deployed. This presumably applies to third-party screen protectors, but we’ve contacted the company for clarification.
Speaking of the software patch, the Korean manufacturer says this patch is set to be released as soon as next week. It adds that users should fully scan their fingers after installing the update.
We’ve emailed Samsung to clarify the affected accessories and will update the article accordingly when they get back to us. Still, we’re glad to see the firm steaming ahead with a fix, so here’s hoping it’s pushed out to users as soon as possible.
