Does this persist after a reboot? How about in Safe Mode, which prevents all 3rd party apps from starting up? verizonwireless.com/support/knowledge-base-94508/ (sorry about the screwy link, but when I try to paste it completely, it doesn't display correctly).
There are alternative methods of opening up settings. I used these methods to get back in and restore settings. I screwed up mine up after reading ways of speeding up the tablet but just screwing it up.
Crazy thing I went to best buy where I purchased my note pro. And it was the proverbial take your car to the mechanic the problem cleared up.
Still do not know what caused the issue.
