Samsung's next generation Galaxy Note 4 benefits from a metal chassis and a larger 5.7in screen. Its Super AMOLED display has a 2560x1440 resolution for a density of 515 pixels in each inch.
Increasing the screen size and resolution to Quad-HD will demand more power, but Samsung has only increased the Note 4's battery by 20 milliamp-hours to 3220 milliamp-hours.
Samsung will ship the Note 4 to Australia with a 2.7GHz quad-core CPU, 3GB of RAM and 32GB of internal storage, which can be further expanded with microSD cards up to 128GB in size. The smartphone will have the same rear camera as Samsung's Galaxy S5 with a resolution of 16 megapixels, while the front 3.9 megapixel camera benefits from a series of improvements.
