I'm sorry, but you have no idea what you're talking about. Do you think this is the first time that any of us have ever used a touchscreen device? I keep a polishing cloth on my desk, and my screen always sparkles. I can't speak for anyone else, but in my case (at least) the phantom screen presses have ZERO to do with an oily or otherwise dirty screen. This problem is not normal by anyone's standard, including the Amazon vendor who I purchased it from. Their replacement unit arrived today and it's (so far) been working fine. I'll make sure to keep my hands clean.
