Samsung Will Release Two Phones
All rumors suggest Samsung will not release a 5.1 and 5.5-inch device like last year. Instead the Galaxy S8 will be 5.8-inches, yet nearly the same size as previous devices due to smaller bezels. Then a bigger 6.2-inch Galaxy S8 Plus will replace the Galaxy S7 Edge.
Both phones will have a 2560 x 1440 Quad-HD curved display. Both will be curved. Rather than one being flat. It won't have a 4K display.
At this point we know nearly everything about the Galaxy S8 and S8+, but will need to wait a little longer before they are released.
