 It is Samsung's first phone with a USB-C connector and the last phone in the Galaxy Note Series to have a home button.Although it is the sixth main device in the Galaxy Note series, Samsung branded its series number as "7" skipping the "6", so that consumers would not perceive it as being inferior to the flagship Samsung Galaxy S7, and to prevent confusion about the order of release due to the same release year (2016).The Galaxy Note 7 is an evolution of the Galaxy Note 5 that inherited hardware components and improvements from the Galaxy S7, including the restoration of expandable storage and IP68 water resistance, and new features such as a dual-sided curved display, support for high-dynamic-range (HDR) color, improvements to the bundled stylus and new software features which utilize it, an iris recognition system, and a USB-C port.
