So I dropped my iPhone the other day and cracked the screen. On the inside. If that makes any sense. I was okay with the crack, until last night when the screen started blanking out in these grey horizontal lines. It looks like dead pixels to me. Has anyone seen this before? Is there anything I can do? Going to attach a pic. Look for the grey (gray) line just under the MacRumors masthead and then there are another two thinner lines lower down. Does anyone have any advice?
