Nope, I don't mean dead/stuck pixels. Here's what I'm trying to say: Bought a Nano, and upon observing the screen to check for dead pixels, I noticed a set of faint dots that make up small squares across the screen (visible at certain angles). I thought, these might be a characteristic of the type of screen Apple is using but then... ...I exchanged my Nano due to a defective battery. Long and behold, my replacement did not have any of these faint dots. I also saw my friends' and yes, some of them don't have them and some of them do. Apple might be using different supplier of LCD's for the new Nano. Do yours have them?
