Samsung's new Galaxy S8, which will be announced officially on March 29 at an event in New York City, will come in two different flavors — a standard 5.7-inch Galaxy S8 proper, and an extra-large 6.2-inch Galaxy S8 Plus. There will be no distinct "edge" version like the last two generations, as both models of GS8 will have curved displays.
Beyond that, the Galaxy S8 and S8 Plus are expected to have extra-tall 18.5:9 "Inifinity Display" screen, which will keep the phones relatively narrow while adding extra screen real estate. The phones will make room for that display by moving to extra-small bezels all around, as well as ditching Samsung's tried-and-true front-mounted buttons for on-screen buttons instead.
The build of the phones is expected to be typical sleek metal and glass, with all of the latest high-end specs inside including a Snapdragon 835 processor. The rear camera is expected to stay at the same 12MP as the Galaxy S7 series, though that doesn't rule out the possibility of different components, specs or processing on the camera.
