There's been a little hubbub in the Android developer community surrounding the lack of proper documentation and source code for some of Samsung's Exynos 4 chips. The absence of documentation has lead to some high-profile CyanogenMod developers giving up on porting to some Samsung devices, including the international Galaxy S3. To cut a long story short, smartphone chips are incredibly complex, and trying to port open-source Android to them without the right code samples and documentation is extremely difficult.
Today, following a short social media campaign, Samsung acknowledged the dev community's desire for full Exynos documentation, saying on its official Twitter account --
We hear your concerns about documentation & source code for Exynos-based devices. We're discussing it with our team and will update you soon.
Samsung has proven itself to be relatively developer-friendly in the past, allowing unlocked bootloaders on devices, and even putting out a special developer edition of the locked-down Verizon Galaxy S3. Hopefully Samsung's internal discussions will result in a positive outcome for devs. If so, it'll mean better custom ROMs for owners of Exynos devices.
