Notification Center stuck in landscape orientation This screenshot pretty much says it all:



Notification Center seems stuck in landscape mode, based on the height and horizontal distance from the edge to the center pulldown arrow. 


The date and top widget update correctly
I can interact with (what I can see of) the top widget
I can't swipe the arrow up to dismiss Notification Center 
I can't interact with the visible screen "behind" Notification Center 


The home button dismisses Notification Center as usual. This behavior has persisted across several restarts.

Interestingly, I can't bring down Notification Center while in real landscape mode. I can get the little arrow tab to come down, but in the wrong spot: 



...but pulling down on the tab just dismisses it. 

Is there anything I can do to troubleshoot this short of a restore?

iPhone 5, iOS 8.3.
Something similar happened to me once like this. Try a hard restart by holding both the power and the home buttons until you see the Apple icon appear on the screen. Let me know if that works.
