For those of you that don’t understand why this is important to Android users, let us briefly explain. Source code for any device is an invaluable part of development for that device. Without it devs are piecing together lines of code and testing things much more rigorously than usual. Having the official Samsung source code makes development a ton easier. Not that their work should ever go unappreciated, but source makes it a lot less difficult to make our devices run as amazing as they should have out of the box.
If you are a developer and aiming your sites on the Galaxy S III for Sprint as your new target device, then you best get to downloading and get to work. Hit up Samsung Open Source for the files now.
