I called Samsung premium care on 12/3 because of as dark mark on the screen. They said it was a factory defect and would send out replacement for free. I received an Email that night saying they would Email again when it shipped. After a week with no news I called back. They saw the claim right away and said yes it was approved but didn't know why it shipped out.They said I would get it the next day, and I did. I expected a generic box with just a phone. That is what Verizon sent out in the past for other phone claims. What I received surprised me, S8 plus in a factory box with all the stuff, charger,cord.adapter,books,everything.And I sent in Verizon black,but this is a unlocked black. Flawless,and working even better than the old one. I called and asked if they wanted the box and all the stuff back,they said no just the phone. So I have to say I am very,very happy with the service.
