Earlier this week, a report published in The Sun claimed that the Samsung Galaxy S10's in-display fingerprint sensor has a security flaw.
Apparently, certain "gel cover"-style screen protectors can confuse the ultrasonic sensor, and if you register a fingerprint while the cover is applied, then the phone can start unlocking itself for anyone’s fingerprint, not just those you’ve registered.
