Multi-tasking is easy with Android™ because open applications keep running even when you open another application. There’s no need to quit an application before opening another. You can use and switch among several open applications. Android™ manages each application, stopping and starting them as needed, to ensure that idle applications don’t consume resources unnecessarily.
Open an application simply by tapping its icon on the screen.
You can customize your Home screen with the application icons you use most often. Applications are located on the Applications screen, but you can copy any application icon to your Home screen for faster, more convenient access.
