This top-end flagship from Samsung builds on the Galaxy S8+, adding an extra telephoto camera, plus the stylus the Note series is known for. The 6.3-inch, Quad-HD screen fills nearly the whole front and drapes around the sides. The body consists of a metal frame and 3D-curved glass on the front and back. Other key features include auto-focus front camera, water resistance, iris scanner, and fingerprint sensor. It also supports Samsung Pay - via both NFC and magnetic card emulation - Samsung's DeX desktop dock, fast wireless charging, memory cards, and 3.5mm headphones.
