My problem with the fingerprint reader in the display is that it just doesn't work well. I'm on a pixel 7 pro, and more often than not it will try and fail a few times, then require a pin unlock. My pixel 5 with the fingerprint reader on the back was nearly flawless.
The one in my Galaxy S22 works great. There is a trick though to make it work even better: Register the same finger twice (and really get all angles). That usually makes the unlock much more reliable.
