Before you apply the fix, let me give you a background of this update.

Galaxy S10 and S10 Plus Biometrics Security Patch

Galaxy S10 and S10 Plus are the world’s first phones to come with an ultrasonic fingerprint scanner. The fingerprint scanner, which was supposed to be the fastest in-display scanner, turned out to be a dud. Samsung was criticized by every single tech segment because of not making the scanner work right. The fingerprint scanner failed for at least 8 times out of 10. Furthermore, the fingerprint scanner fails to work under glass screen protectors. Ultrasonic fingerprint scanner uses Air to transfer sound waves in order to cast the thumb impression on the scanner. When you use a glass screen protector, there is no room for air between the screen and scanner. This is why it fails to work with those protectors. It didn’t take long for the glass screen protector companies to come up with a solution, but the fingerprint scanner’s functionality was yet to be improved by Samsung. The South Korean giant promised to fix fingerprint scanner problems in a software update.

Galaxy S10 and S10 Plus owners were blushing out of happiness after seeing how fast the fingerprint scanner has got. Galaxy S10 and S10 Plus may have the fastest under-display fingerprint scanner after this update. Not only the fastest, but the ultrasonic fingerprint scanner is also much more secure than the optical readers.
