For the Action Button, go to Settings>Action Button and make sure that something is actually selected. Sometimes, an update borks the settings.
What do you mean by "the touch screen is missing touches?" Are there particular areas of the screen that aren't working? Or is it random? The first thing I'd try is a forced restart.
