Bests & Worsts Reviews from Amazon

The US Warranty listed is not valid. When I received my phone, I tried to register it on the Samsung website and received the error message: "Possible reasons for the error include serial/IMEI number is not valid, product is older than 3 years, product was purchased outside the U.S." Contacted Amazon, and a replacement phone was sent out. When I attempted to register it, I had the same problem. After spending an hour with Samsung customer service per the number in the warranty listing, the phone does NOT have a US Warranty available.
