core of note 4 has two types. The version sold in North America and Europe is based on Qualcomm's Xiao (SnapDragon 805), while in South Korea and some other parts of Asia, Samsung's own Orion Chip (Exynos 5433) is essentially the same. The Xiao Chip is a quad-core CPU specification, and Orion has eight cores, which correspond to two Gpu:adreno 420 and mali-t760 respectively. Note 4 is also divided into two systems by the nearest Google. Respectively, are Android 4.4.4 (KitKat) and 5 (
The kernel fixes a Local Elevation of Privilege Vulnerability that affects a large number of Android devices.
