The Samsung Galaxy Note 4 is the successor to 2013's Note 3. It has not been announced officially, but will be presented at the IFA technology fair in early September 2014. Through various leaks the device is expected to have a 5.7-inch QHD Super AMOLED display with S Pen stylus. Two variants will be available, one with an octa-core 64-bit Exynos chipset and another with a quad-core Snapdragon 805 chipset. Both versions are expected to have 3 GB of RAM and a 16 MP camera with OIS. A heart-rate sensor is likely, as is a finger scanner, but rumors persist about an iris scanner. This description will be updated as more details come to light.
