OK everyone!! This is a solution to your issue! This occurs when you Uninstall Samsung Hub from your device. They hide the library file that is needed inside the APK. To restore this funtionality, you need to get a copy of the... libgnustl_shared.so file either out of the /system/lib directory before removing the app, or reinstall the app side loading and retrieve the file that way and restore to it's home in the system library. Once copied and ch'd restart and screen rotation will work again!
