Short story: Put an iPad 3 on sale on July the 5th. Put it into its original box and then into a wardrobe so nothing could happen to it. This last friday a guy told me he was interested and we agreed the terms. I got it today in order to charge it again and restore to 6.1.4, but this ****ING thing appeared on the screen. As you can see in the video, it's only visible when the screen is on and it responds to the touch as normal. Any ideas what could cause this? I'm reproducing now 1080p video 24/7 in order to see if it goes away Video: https://www.dropbox.com/s/95m5cmi8tmg8x3q/IMG_0660.MOV EDIT: No applecare and it's more than 1 year old.
