The Galaxy S10 and the Galaxy S10 Plus are equipped with the latest and latest ultrasonic fingerprint sensor on the screen that is much safer than an optical scanner that other phone manufacturers are using as a solution.
However, there are some drawbacks with the Gen-1 ultrasonic fingerprint scanners, and some users have reported that the fingerprint sensor on their Galaxy S10 does not work .
Possible solutions:
Well, first and foremost, if you have installed a tempered glass screen protector for your Galaxy S10 recently, remove it, because that is likely to be the problem.
This is because not all tempered glass works well with the new ultrasonic fingerprint sensor technology on screen that the S10 and S10 Plus models mount on top of it. You need to install a special tempered glass compatible with your Galaxy S10 .
However, if you are using the Galaxy S10 with the same screensaver that came pre-installed, then obviously the problem is not there. Therefore, although some users have reported better fingerprint sensor performance after removing even the Samsung screensaver , you can test this before diagnosing that already, then, it would be a problem at the hardware level.
