Yup the fingerprint does not work good with this screen shield installed I did try to introduce the fingerprints after installing the screen protector again to see if it changes anything and it doesn't, so if you planning to use fingerprints dont buy this screen protector
Yes it does work. The screen protector will crack before your screen will. I have one on my iPhone as well and it did crack but my screen did not when I dropped it. I just peeled it off and put a new one on.
