I just upgraded my iPad 2 WiFi to iOS 7.0.4 and noticed this bug that's really strange:
No matter what I do, I can't bring up the control center when the iPad is in portrait mode. When in landscape, it will come up with a swipe just fine!
More bizarre, when I hold it upside down (the front camera on the button), the control center also shows!
Anybody has any idea what's going on and is there anyway to solve this?
