I seem to have oleophobic-proof fingerprints then. I'm constantly cleaning phone screen (swipe on jeans these days now phone is not spanking-new).

You could easily see my swipe or pin pattern from prints and smudges, even from one use, which never happened with actual keys.

The oleophobic coating does vanish with use over a period of time. That's why you wouldn't see fingerprints and such on a new device, but would on an older and well used one.
