I imagine if Samsung found it as a defect in manufacturing, then they would replace it. Looking at that picture, I don't know how they would think that that could have been caused by the user unless they think you were for some reason picking on the button with a screwdriver or something. It's certainly not old enough for wear and tear. I hope they replace that for you. Maybe they'll give you a new one since they probably don't have refurbished units yet.
