Why Hardware Hacking? The upcoming release is expected to be an "international variant". Generally Samsung designs their International variant which all carrier variants are designed upon. The various GalaxyS3 devices are expected to be generally similar across the board. Information which applies to one model can be applied to other models, with additional datasheets added into the hack-pack.
Exynos 4412 (S5E4412) is a 32-bit RISC cost-effective, low power, performance optimized and
Coretex-A9 Quad Core based micro-processor solution for smart phone applications. To provide
optimized hardware performance for the mobile telecommunication services and general
applications on smart phone, Exynos 4212 adopts 64-bit/128-bit internal bus architecture and
many powerful hardware accelerators for different tasks. These tasks, for example are, motion
video processing, Image Signal Processing, display control and scaling. Integrated Multi Format
Codec (MFC) supports encoding and decoding of MPEG-2/4, H.263, H.264 and decoding of VC1. This
hardware Encoder/Decoder supports real-time video conferencing and digital TV out.
The memory system has dedicated DRAM ports and Static Memory port. The dedicated DRAM ports
support LPDDR2 interface for high bandwidth. Static Memory Port supports NOR Flash and ROM type
external memory and components.
To reduce the total system cost and enhance the overall functionality, Exynos 4212 includes many
hardware peripherals, such as TFT 24-bit true color LCD controller, Camera Interface, MIPI DSI,
CSI-2, System Manager for power management, embedded GPS and GLONASS, MIPI slimbus interface,
MIPI HSI, four UARTs, 24-channel DMA, Timers, General I/O Ports, three I2S, S/PDIF, eight IIC-BUS
interface, three HS-SPI, USB Host 2.0, USB 2.0 Device operating at high speed (480Mbps), two USB
HSIC, four SD Host and high-speed Multimedia Card Interface, Chip to Chip interface, and four
PLLs for clock generation.
Package on Package (POP) option with MCP is available for small form factor applications.

We need to find a real datasheet on this Exynos processor, but I've yet to find one. Please post related datasheets in this thread.
The best way to collect a bulk amount of information on a new device is to install Elite Recognized Developer Supercurio's "Voodoo Report" from the android market https://play.google.com/store/apps/d...tvoodoo.report. Once we have a Voodoo Report, we can extrapolate data and begin collecting information about the rest of the device.
If you happen to get ahold of a GalaxyS3, please run a voodoo report and send it to me at (my username)@gmail.com
Credits and thanks

I think it's worth noting that anyone who has early access to this phone, also please take some high resolution internal pictures of the circuit board, and post links to them here, so that we can confirm the hardware used and search for undocumented chips etc. Also here is the Supercurio (?) live Google document for SGS3 internal specifications.
^^ I'm slightly disappointed with the fact that iFixit now just gets their pictures from Chipworks. Before, they actually made a good complement to each other. In addition I'm a bit dissappointed in the quality of those pictures as they are not as close to the PCB as is the SGS2 photo coverage. Thus we still need better closeups!
But I am grateful for any pictures at all and also thankful to those websites that attempt to provide us with useful details!
So while having a first look at the i9300 mobo, the 3 region related jumpers, jumped out into my eyes like a glowing iron! AFAICT, they seem undocumented in the Service Manual, and elsewhere. I'd like to know more about these and what chip and pins they are connected to.
Obviously (?) the region codes refer to: EU = Europe AU = Australia IN = India
From HTML to LEDs or Android to Arduino, Hardware Hacking is a pastime of many people … more
