OK, but that doesn't sound like ranchogirl's problem. She's saying her phone forgets her fingerprints by the next day. So maybe it is a defective unit. But even still, why does the phone do that after 48 hours? Did they give an explanation? Do you have a link to the actual article?
Wait, what? It is designed to forget your fingerprint scan? What does rescanning mean (I don't have the 5s yet)? Does that mean you have to re-train the system to recognize your fingerprint? Everyday? Wouldn't that be like the phone forgetting your passcode and you have to reset it every day? How is that convenient? I must be missing something. Do you have a link?
