The top of my iPod touch screen is darker than the rest of my screen after the newest update?
So today I turned on my iPod touch (5th generation) and it said there was a software update available. I updated it with no problem, but after the update I noticed almost half of my screen was darker than the rest at the top. (Posting screenshots below) I don't know if it's supposed to be like that because of the update or not. Also, I have a little blue dot (assuming it's a 'dead' or 'stuck' pixel) on my screen that was there when I bought the ipod BRAND NEW on February 13th of this year and I'd like to know if that may be affecting it? Any help would be appreciated!
