I had a 1-year old mint Galaxy S7 that I bought directly from Samsung the previous holiday season. The phone worked perfectly but I decided to upgrade to the S8 due to special holiday trade-in offer. My S7 never gave me any problems and I went down their checklist for a trade-in and my phone passed every item in their list. I sent it back in the original packaging with everything included. They rejected my trade-in, charged me an additional $375 and kept my S7!! I have been a Samsung customer for years and have appliances, speakers, monitors and a printer but I will never buy anything from Samsung again and I recommend you don't use their trade-in programs.
