This rom supports all the Samsung Galaxy S3’s and S4’s. It is CM11 which is running Android KitKat 4.4.2, the latest version of android. Let me just say that it makes your S3 and S4 a whole lot faster. It performs almost as fast as the nexus 5! I hope you enjoy this video. I recommend you check this rom out.
