Re: Smudges?
They can avoid registration of a 'flat' fingerprint, but instead of having everyone able to unlock their phones no one will be able to unlock their phones if they are using a screen cover. I guess it is secure, but then might as well not have a fingerprint sensor as far as all those people who use screen covers are concerned.
Not sure why they abandoned the rear fingerprint unlock, other than everyone was talking about an under-display sensor and Samsung didn't want to seem behind the Chinese companies (even though they are probably using the same Qualcomm solution Samsung is) I think a rear sensor would be less convenient but it is better than a partially functional front sensor.
