First of all galaxy 2016 got new tuchwiz with theme support but it’s not updated with that even its running now marshmallow it’s have some unique features
The first QHD AMOLED screen and the first Snapdragon 805 smartphone to go global as well as the best S Pen yet - the list of things for Galaxy Note 4 owners to brag about is certainly not a short one. But a flagship’s worth is not in the number of exclusive features - the areas where it fails count double against it. And while the Galaxy Note 4 has very few things to be ashamed of, it’s our duty to check against any nasty surprises. Main disadvantages
› Rear-mounted mono speaker
› microUSB 2.0 is a downgrade over microUSB 3.0 on the Note 3
› The uneven gap between the metal frame and curved screen glass takes a few points away from an otherwise excellent build
› No enhanced resistance to liquids or dust
› Wireless charging support only with an optional back cover
