Both myself and a coworker installed the Sprint 4.4.2 ota. After the first boot you will get a dialog that says Android update complete. .. When you click ok there is a second dialog Device Update Complete that disappears. At this point, finger touches would not register on the device and you could not use the screen.
The fix... use the s-pen. It will still work. Reboot one more time and you will be able to hit the ok on Device update complete and all will be well.
