It should still have the warranty, I don't believe Samsung checks where you bought it, at least they never asked me when I called for warranty support. With Samsung warranty support being so utterly useless I'd just get squaretrade anyhow, you can get it for eBay purchases.
Okay, with the price difference between what I had before and this, I paid up for the Note 5. I'll be coming back now that it's somewhat more worth it.
