A slightly different application of glass

You can only eliminate this by peeling off the glass and trying to position it again and better. If none of the corners "click", you're done. I mean, almost.
Fingerprint reader
It is still advisable to try to better adhere the area for the fingerprint reader. Just take the included cloth and rub it hard over the area, or you can use a fingernail. You can then peel off the second part of the foil. It is still worth running a cloth over the sides of the glass so that it ideally adheres to the display. Of course, the individual steps are also written on the product box.

In addition, if you use polarized glasses and look at the phone with applied glass, you will see this ring with a hint of green, which is not very nice and somewhat spoils the impression of the great display that Galaxy The S22 Ultra has
After applying the glass, it is also advisable to load the fingerprints again, when you should do so at least twice in the case of the primary one, in order to increase the accuracy of its recognition.
