In brief, the kernel is the part of the Android operating system that handles input and output requests from hardware.
It translates commands between your device’s software and the hardware, and is thus an integral part of any mobile handset.
The new availability of the handsets’ kernel source code means that developers can now begin creating custom Android ROMs for both devices.
Unfortunately it’s not quite that simple, as Samsung has yet to release documentation for its mobile chip.
Samsung made the bold decision to include its own custom-built Exynos 7420 chipset on the company’s most recent flagship smartphone releases.
Qualcomm offers up detailed documentation for all of its Snapdragon series mobile chips, but Samsung guards its own chip information more closely.
This means that because developers can’t access the source code for the in-house chipset included on the S6 and S6 Edge, the creation of custom ROMs is hindered.
The handsets are Samsung’s latest flagship smartphones, and went on sale just last week, on April 10.
