Latest leak suggests that Samsung Galaxy Noe 4 will carry the similar colors as Galaxy S5 at the time of launch. This means Galaxy Note 4 will come in black and white variants for all carriers and in all markets.
Samsung added copper gold color variant to Galaxy S5 line up recently, but the latest leak does not say anything about this newer color. So we do not expect gold-colored Galaxy Note 4 at the time of launch.
Also it is almost confirmed from previous rumors that the phablet will come in both Snapragon and Exynos variants and going to be released sometime in September. Other rumored specs include a display with a resolution of 2560×1440 and screen size is 5.7 inch, 3 GB of RAM, 32 GB of internal storage, and a 16 MP main camera complemented by a 3.6 MP front-facing sensor. The phone seem to be running on Android 4.4.3.
