I don't know what this is, but when I looked at my screen today on a white screen, I noticed a very small black dot or speck. At first I thought it was just some dust so I brushed off the screen - but it was still there! I even flet over the area to make sure it wasnt a scratch, no scratch! perfectly smooth on top. I even restarted the phone to see if it was some software display issue. Nothing is making this stupid thing go away! I have never dropped the phone or anything, does anyone have a clue what it is?
