Yeah. It selects 0, 90 and 270. But once I hit back, it disables it again. If I go back to the home screen, it disables it again. If I enable it, rotate the screen and go back to my home screen, it is disabled again.
Even flashed the ROM again, cleaning the Cache/Dalvik and System and still happens.
Figured it out. Feel like an idiot as well. Must have installed when I tried out the TouchWiz UX Launcher but an app called Smart Rotator was installed for some reason. It locked everything into portrait mode. Uninstalled the app and got my rotation back. DUH!
