Samsung will be offering another flavor of the Note 4 with its proprietary Exynos 5433 chipset, which packs an octa-core processor with four Cortex-A57 @ 1.9GHz and four Cortex-A53 @ 1.3GHz, Mali-T760 graphics and 3GB of RAM. The only other real difference between the two models is the Snapdragon-powered flavor offers LTE Cat.6 (300Mbps) connectivity, while the Exynos-based version stops at LTE Cat.4 (150Mbps).The Samsung Galaxy Note 4 incorporates the new design introduced by the Galaxy Alpha - a stylish metal chassis, high-quality rear plastic cover and protective screen glass with rounded Lumia-like edges.The new battery cover of the Galaxy Note 4 is very similar to the Note 3's, the faux-leather pattern is almost identical though the stitching is missing this time around. Even though the plastic is super thin, it fits perfectly on the back and feels as solid as possible. You can't tell what it is unless you open it. The Note 3 was made the same way, so no surprises here. And we like the new cover without the stitches better.
