The Star 2 Plus is powered by Android, a Linux-based, open source mobile operating system developed by Google and introduced commercially in 2008. Among other features, the software allows users to maintain customized home screens which can contain shortcuts to applications and widgets for displaying information. Three shortcuts to frequently used applications can be stored on a dock at the bottom of the screen; the button in the right of the dock opens the application drawer, which displays a menu containing all of the apps installed on the device. A tray accessed by dragging from the top of the screen allows users to view notifications received from other apps, and contains toggle switches for commonly used functions. Pre-loaded apps also provide access to Google's various services. The Star 2 Plus uses Samsung's proprietary TouchWiz graphical user interface (GUI).
