Here is the policy on Samsung website. If I'm reading it right, if you buy the phone from sites such as swappa and eBay, not the original purchaser, Samsung warranty does not transfer to second buyer. Samsung may not always enforce these rules as it States it's up to Samsung in the long run.
Read number 1, number 7 under general terms and conditions. And number 1 under warranty guide.

I bought mine through a reseller who does this all the time and I was able to register it and Samsung confirmed my warranty. If you buy from an individual that bought it for himself that may be an issue especially if he registered it. LG has a similar written policy and I had them service a new unit purchased from a eBay reseller more than once. They asked for a receipt and actually accepted the eBay bill of sale.
There is always a risk if you don't know who you're buying from.
