I have an issue with touchscreen once in a while. It may start to act like I'm pressing the same area many times or may not react at all. Sometimes screen is shaking like I'm trying to flip screens but not pulling to side enough. Changing stock ROM to CM7 gave no difference. Looks like it's a hardware problem because I'm getting it when the phone is hot (charging, playing games, on the sun etc.) Cooling down and lock/unlock helps every time.
BTW, I've broken digitizer, can anyone advice me a store or Seller on eBay to get new one from? Are these Chinese digitizers OK?
