Samsung said in a statement: “If you’ve used a screen cover, such as silicone cover with a textured surface on the inside, the texture itself may be recognized as a fingerprint that can unlock your phone.”

According to Android Central, Samsung is now rolling out a fix to “all affected phones” in South Korea – so that’s any S10 or Note 10 phone that has an in-screen fingerprint sensor. The only one that doesn’t is the S10e.

If you use a silicone case over your S10 or Note 10 screen or are just worried about this in general, you can remove fingerprints from your phone in settings until the software update is pushed out. Samsung recommends re-enrolling your prints after the update either way.
