I really know nothing about smartphones. However, what I'm gathering from finding this sweepstakes is that the Samsung Galaxy 6 phones are not available yet. It's their Next Big Thing, to use their own words.
What can you win?
One grand prize winner will win the entire Samsung ecosystem (as they call it!) worth over $3,500. It consists of a Samsung 55” Curved Smart TV, a Samsung Galaxy S 6 device, a Samsung Galaxy Tab® S device, a Samsung Galaxy Gear S™ device, a wireless charging mat, a Samsung Galaxy Gear™ Circle device, and a Samsung sound bar with wireless subwoofer.
