The Galaxy S9 ups the ante on last year's Galaxy S8 by bringing an upgraded camera with tricks like variable aperture, super slow-mo video and 3D avatars called AR Emoji. It also packs a blazing fast Snapdragon 845 processor and a similar all-screen design as the Galaxy S8. Although we've discovered a few weak spots in some apps, the Galaxy S9 is set to be one of the best phones of the year.

Scroll down for the carrier deals, but keep in mind that they all work about the same way. You'll get your discount through a billing credit, which kicks in after one or two bills. All carriers require you to be a well-qualified buyer (that means you pass their credit check), and you'll have to pay the remainder of what you owe if you back out of the agreement or leave the carrier.
