I changed my wallpaper on the screen and I still see a little orange in the upper left hand corner. But the rest of th screen is black which is the background I chose. The orange in the upper left corner is making me nervous that there is a problem with my screen. Any suggestions?
Its hard to explain..... it dosent look like a notifier. It looks like the full wallpaper dosent cover the entire screen.
I have this too; almost seems like the screen is not aligned properly with the black boarder (top left side/corner for me); but I don't think that is the case. Its the background showing through the various application screens. I don't think its anything to worry about.
I have not tried swiping. I just tap the exclamation point to open the message. What you are seeing is the new message indicator nothing is wrong with your screen.
