You're the first one to say that it's been fixed. I just find it hard to believe that everybody else is having this issue except you. But good for you.
EDIT: apparently there's a few other folks who are not seeing this issue. Just to be clear, when you open a picture in the Messages app and make it full screen, do you not get the status bar showing up over the picture?
I dont have the issue either. iPhone 6 iOS 8.1 b2.
