Same crazy problem
I have a :motdroidvert: Milestone that I bought from Amazon (with no warranty) about a month ago. It was fine the first week, up until the day I received a cover which came in late. It brought a plastic shield for the front of the phone, which can be applied with a bit of soapy water. Something I did applying this thing became the problem because it was right after doing this that the phone started doing crazy things, as if a bunch of fingers were pushing buttons on the phone. Either the soapy water or maybe the pressure I did to it sticking the shield. Who knows, but I was really careful, I didn't think I could damage it in any way. So now it works ok "most of the time" that I'm in the house, but when I go out, when I pull it out of my pocket the screen wont answer, or it would start pushing things by it self. Sometimes I can't even answer a phone call. So annoying I went back to a little crappy samsung I had before buying the Milestone.
Recently I bough from eBay a new screen digitizer that they sell for $35 dollars, from a place in Hong Kong. I am waiting for this anxiously, since it is my only hope right now. Later on we'll see how the results.
Any other solutions?
