Just wondering if something specific could cause them or simply a quality issue. My first N1 (T-Mobile purchased day one) developed a tiny dead pixel after about a week of use. I returned it to HTC and the replacement I got didnt have any but about a week after I got it, a dead pixel appeared on it. The phone was stolen so I never called HTC. I just bought an ATT N1 and again it's perfect to start. I know nothing about how electronics work but I wonder if: -Could a specific live wallpaper cause this? I used the Grass one on both previous models. -Could the dock cause this? When you place it in dock the screen dims and you get that floating clock. I wonder if extended stay on the dock could be the cause? Or like I said maybe just not the best quality parts. Any ideas? I would like to avoid getting any this time.
