The final remaining oddity is that inexplicable white square in the center bottom of the screen, the white square that I can't remove and that does literally nothing. It might bother me more than the off-center buttons. I am now considering creating an Android app which has an icon the exact color of the nav bar, which when launched does nothing except quit to the home screen. That is really, really silly. Maybe it's less work than returning the darn thing and buying a Galaxy I won't like either
