There's also the issue that the device is covered in fingerprints, and if you can build a clean image of the print, you can likely manufacture a gelatin copy of that fingerprint that will work on most fingerprint scanners.

I can't speak to the current generation of Apple fingerprint scanners, but historically iirc you can grab a print, clean it up in Photoshop, print it on OHP transparency using a laser printer and use it like a mould to copy a fingerprint.
