You can buy used phones on Swappa and EBay. We are not allowed to sell our phones here unfortunately.
Also if you bought the phone new with a credit card, many credit card companies extend the warranty for another year.
Try Amazon, Swappa, Ebay, or Craigslist. Phones aren’t allowed to be bought sold or bartered here in the community. It is against the community guidelines.
