You're right - it definitely shouldn't do this. In another thread you also posted that you're having heat issues. I suggest that it's time to pursue a warranty repair. Apple will stand behind their product. Let them.Mine worked flawlessly up until this week. Now it doesn't work right no matter how I touch it. It definitely shouldn't do this.
Have you tried deleting, then adding the fingerprints again?Mine hardly work at all now,stupid gimmick from Apple if u ask me
