First, I don't believe this is a screen protector issue. Prior to galaxy s22 ultra, i had no real issue with fingerprint biometric performance . But with s22 and now s23, my prints start malfunctioning almost right away. They work for about 2 -3 weeks, then my print registry start to degrade o,r loses functionality, and they are no longer recognized. Also, I have great difficulty registering my prints at all. The reader gets so far, then stops. After a certain amount of time, the system makes me start over. Sometimes, it takes over an hour to get just one fingerprint set. This issue isn't because I'm inexperienced or doing it 'wrong'. There is something wrong with the sensor hardware/software. This is really irritating. As soon as the os and apps are aware of change, I have to redo the lockscreen for every app that I've set up fingerprint unlock in every place it is available. Now, I'm in the process of removing that requirement. The new issue is that the fingerprint unlock requirement in Samsung Wallet can not be disabled, as far as I can tell. There is an option to disable the fingerprint requirement anywhere. I believe that it is hard-coded. I am frustrated and am migrating my Samsung Wallet and Pass info to other apps. Too bad, I really liked the way it worked otherwise. Yes,I I've tried moistening my fingers, warming them up, etc., etc., etc. Too bad. I like the idea of fingerprint unlock, but it's too time-consuming and irritating to keep redoing it!
