Can anyone explain how well this coating is supposed to work? I mean, if you touch the screen, does it never smudge? Or do smudges disappear later? When I first got it I was wiping it all the time, since it seemed worse than my 3G. But if I leave it alone, it seems to clear itself. However, from reading, it seems your supposed to wipe it on a clean cloth. So, can anyone explain just how this is supposed to look and how to treat the glass after a fingerprint?
Well, I have a 3GS and I think the IP4 coating is better. Perhaps its better in concert with the new glass...but I see a difference.
From what I understand, you still get fingerprints, and they don't magically disappear. It simply makes it (supposedly much) easier to wipe them off. On my Power Support screen protector on my iPod touch, when I wipe it, it just smudges around and it takes a WHILE to wipe off an hour's worth of finger prints. Supposedly on the ones with oleophobic coatings, you wipe it once or twice, and it's fully clean. I've used 3GSs and it seems pretty good, but I'll get some first-hand experience when my iP4 comes in.
I'm not trying to be a jerk, but if it takes an hour to wipe your screen clean, maybe wash your hands a little more often. Im seriously not trying to be an ass, but yeah washing, or purell, something if your hands are that grimey! I have the same issue, I work with my hands all day, but if I wash them alot, I notice the oily nature of them decreases during the day!
