Jiayu S3 and S3 Plus are your typical Android smartphones powered by Mediatek MT6752/MT6753 octa core Cortex A53 processor with 3GB RAM, 16GB flash, and a 5.5″ touch screen display. The news here is that Jiayu Germany (a reseller, not the manufacturer), and Team M.A.D (Mediatek Android Developers) comprised of XDA members, have releasing three custom ROMs based on Android 6.0.1 for the smartphone: Cyanogenmod13, Paranoid Android (AOSPA) and AICP (Android Ice Cold Project), which contrast with my Iocean MT6752 smartphone still stuck on Android 4.4.4.

The phone normally runs Android 5.1, and ships with the battery, a USB cable, a charger, and a user’s manual.
Beside the firmware release, you’ll also find the source code for Linux 3.10.65 and “Device” source tree for both phones, as well as proprietary vendor files on MediatekAndroidDeveloper’s Github account. Sadly there’s no Wiki or documentation at all, but it should be possible to build it from source if you are familiar with CyanogenMod.
Jiayu S3 does not appear to be for sale anymore, but Jiayu S3+ is still sold for $155.99 on Banggood, and Aliexpress.

I’ve got confirmation that Jiayu (China) – the manufacturer – was not involved at all in this code release, and only Jiayu Germany – the reseller, unrelated to the manufacturer – took part in the development.
