The Samsung Galaxy Note 4 is the first of its line to have a metal body, giving it both strength and a premium look. The device is larger than most mainstream smartphones and of course comes with a very precise stylus and software that takes full advantage of it. The Galaxy Note 4 is aimed at power users who need to multitask and be productive all the time. It has a 5.7-inch, 1440×2560-pixel screen, 2.7GHz Qualcomm Snapdragon 805 processor, 3GB of RAM and 3,220mAh battery. It supports LTE data, Wi-Fi ac and Bluetooth 4. There’s also a fingerprint sensor for security, and a heart rate monitor which is not all that useful.
