Like the Galaxy S6 series from last year, the S7 lineup should include devices with flat displays, as well as with curved ones. An image posted today by Evan Blass (aka @evleaks) suggests that Samsung is planning to launch three S7 models: Galaxy S7, Galaxy S7 edge, and Galaxy S7 edge+. A Samsung Galaxy S7+ may also be in the making, but it's not mentioned here.
While the Galaxy S7 is expected to sport a flat, 5.1-inch Quad HD display, it's not clear what sizes the dual-curve screens of the Galaxy S7 edge and S7 edge+ should have. Anyway, Samsung could go with the same sizes that it used for the Galaxy S6 edge and Galaxy S6 edge+: 5.1 inches, and 5.7 inches, respectively.
As you can see in the image below, the Galaxy S7, S7 edge and S7 edge+ logos are shown on a background that seems to include tiny water drops. Not long ago, we heard that the S7 series would be water-resistant (like the Galaxy S5 from 2014), so the background makes sense. Of course, anyone could make an image like this, pretending it to reveal the logos of these upcoming Samsung handsets. However, @evleaks usually posts genuine images and info, so, at the moment, we're inclined to believe that these are, indeed, the logos of Samsung's next-gen high-end smartphones.
Compared to the Galaxy S6 family, the Samsung Galaxy S7 series should bring notable changes. Besides water-resistance, the new smartphones may feature microSD card slots, always-on screen functionality, larger batteries, and 12 MP rear cameras with big sensors (these should be better than the 16 MP cameras of the S6 models). Stay tuned as we try to gather more details about this.
