Out of all of the Galaxy S7-series phones that I've seen, the majority of them have been the smaller, 5.1-inch model. That's odd, considering the fact that the S7 edge outsells the S7, but it's entirely understandable why people would choose the S7 over the edge model; it's easier to hold, less prone to accidental screen touches, more durable, and less expensive.
With those things in mind, have a look at this: according to VentureBeat's Evan Blass and The Bell, a Korean publication, the Galaxy S8 will come in two phablet-sized, dual-edged variants, and the larger of the two will feature an enormous edge-to-edge display. Wow.
The "small" Galaxy S8 will apparently sport a 5.7-inch display with Samsung's trademark curved edges. That screen size is 0.2" larger than this year's Galaxy S7 edge's, and the same as the now-discontinued Note7's.
Curious about what the S8 plus might look like? Think Xiaomi Mi MIX.
The larger S8, rumored to be called "Galaxy S8 plus," is slated to sport a gigantic 6.2-inch edge-to-edge display. It, too, is said to have a curved edge display, but more interestingly, it will apparently ditch Samsung's signature home button/capacitive key combo for on-screen keys. This would make it the very first Samsung phone with software navigation keys (let's be honest, the Galaxy Nexus doesn't really count).
Internally, the S8 is known as SM-G950, and the S8 plus SM-G955. To Samsung enthusiasts, this may seem strange, as the S7 and S7 edge were designated SM-G930 and SM-G935, respectively. Apparently, the (silly) reason behind the decision to skip SM-G940 and SM-G945 is a tradition rooted in many Asian countries; the word for "four" sounds like "death" in a few Asian languages, including Korean. In fact, there's even a term for this - tetraphobia (literally, the fear of four).
The decision to ditch a small flagship will no doubt be a controversial one; after all, the only major players that still produce smaller premium smartphones that aren't under-specced are Apple, with its iPhone 7, and now Google, with the Pixel. You may be led to think that the huge increase in screen sizes is to fill the void left by the Note lineup, but this tweet of Blass's says otherwise.
The designation of SM-N9xx has always been used for Galaxy Note phones.
Amidst all these rumored shakeups, Samsung is still expected to take the wraps off of the Galaxy S8 line of phones in late February/early March at MWC 2017 in Spain.
