A few days ago, the owner of the Galaxy S10 complained that her husband was able to unlock the phone with his fingerprint, although not registered in the phone, and Samsung promises to update soon to fix the problem.
The problem with fingerprint recognition is caused by the use of a protective screen protection cover in a way that some fingerprints are compatible with the recorded fingerprint and then anyone can unlock the phone.
The Galaxy S10 has an on-screen fingerprint sensor and uses ultrasound waves to identify the fingerprint and verify its identity. Due to the screen protection label, plastic and silicone adhesive fibers and ultrasound are blended, resulting in a defect identification.
As a result of this serious security flaw, some electronic banks such as KakaoBank in South Korea have advised their subscribers and account holders not to confirm their fingerprint identity until the problem is resolved.
Some previous reports say that the fingerprint sensor can be deceived by printing a fingerprint on the 3D printer and verifying it.
Samsung advises users to use a fingerprint or to use original on-screen labels designed specifically for Samsung agents by agents.
