So I was showing off my droid the other day and attempted to wow the audience by keying the scratch proof screen. Note that I do not have any screen protection yet. They were wowed allright but the next day I noticed very very faint scratches on my screen. I gave the screen a good rub with my shirt and they disappeared along with the smudges and dust so i didnt think anything of it. I just checked again a few min ago and I saw those same scratches imprinted in the dust and smudges that had gotten on the screen. I again gave it a good rub and they dissappeared...but I'm starting to wonder how the heck is this even happening?!?
