Have you had it worked on before it started this problem or did it just start doing it out of nowhere or maybe dropped it or knocked it off and jarred something loose. Also if the screen has gotten moisture to it it'll change and you'll be able to see the warning. Just hit me could be the battery in it leaking. I would contact samsung. It should still be under warranty through samsung and you may not know it or the seller doesn't want to honor their warranty because the haven't been out but around a year maybe13 or 14 months tops in Virginia anyways.
