    The screen moves up and down quickly about 1/4 inch.
    This happens for about a second, then the tab 2 freezes.
    Pressing the power button quickly turns the screen off.
    Pressing it again turns the screen back on to the home screen.
    Swipe the screen to the right and the screen comes back on right where it was.
    Tab 2 works fine until it does this again. No pattern to when it happens.
    Reinstalling firmware does not help.

    Any ideas what going on, how to solve?
    Is it software... hardware?
    Sell it for parts?

    Welcome to Android Central! Considering you already reinstalled the firmware, it sounds more like a hardware problem. The only other thing I would suggest is try booting into Safe Mode, to see if it's due to some 3rd party app: https://support.t-mobile.com/docs/DOC-18895
