The Spigen requires a specific installation process, which must be followed in detail !!!!!
There is a video on the Spigen site.
I didn't think I would succeed on the first try. On a different device, etc., I had to buy the corresponding set for the second time.
It made me two small flaws, one with a diameter of one millimeter, and one with a diameter of 2 millimeters.
I can't explain it, given that it went crazy there, it's about the center of the screen.
Before I put on the Spigen, I put on a no-name glass, the fingerprint didn't work at all.
With the Spigen, the fingerprint is difficult to work with, the second - third time, there is generally a problem .. if I moisten my finger a little, then it works, unknown why. I think it's a matter of the fingerprint sensor that the phone has, and not the glass.
I had read something on google, that there are different types of sensors etc etc, light doesn't pass etc, I don't remember...

Excellent case for the Note 20 Ultra that, while not adding extra bulk to the already bulky device, adequately protects it while providing good grip. Highly recommended for anyone looking for something discreet and beautiful.
