Scoured Google and MacRumors for this issue, but couldn't find it. Sorry if there were previous posts discussing this issue. If I put my iPod touch on a surface, say, a table, then occasionally, when I tap it, it will interpret it as a tap elsewhere or as a pinch. I am completely sure my other fingers are not touching the glass surface. Recently, I discovered that if I hold the metal frame or back while tapping, the issue suddenly stops. If I stop holding the frame or back, the issue comes back. Does anyone else have the issue? Is it a hardware defect? Thank you. Sorry for my bad English. I am not a native speaker of English.
