I was still able to scroll sideways to access my lock screen widgets, but swiping did not unlock (and I know for sure I was doing it properly, on the proper screen, without the widget being expanded).
Eventually it worked again after turning the screen off and on, and I guess I thought the Home button had something to do with that issue.
