I just opened my new hp touchpad and as far as I can tell the center/home button doesn't work. It does nothing when I press it at the home screen or in an app. Took me for ever to figure out I can swipe up to get out of an app when I was stuck in one. Hp me had me do an erase of it which didn't help, then they had me do the doctor update which is still going at the moment. Has anyone else had this problem?
