Multi-tasking is easy with Android™ because you can use and switch among several open apps. Android™ manages each app, stopping and starting them as needed, to ensure that idle apps don’t consume resources unnecessarily.
Open an app simply by tapping its icon on the screen.
You can customize your Home screen with the app icons you use most often. Apps are located on the Applications screen, but you can copy any app icon to your Home screen for faster, more convenient access. No matter where the icon is, on the Applications screen or your Home screen, just tap it to open and use it.
Tap an app icon to open it.
Tap the Home Key (in the Touch Keys bar).
If the app icon you want is on your Home screen, simply tap the icon to open and use it.
Tap the Apps icon (in the QuickTap bar).
Tap the Apps tab (if necessary), then tap the icon for the other app you want to open.
Tap the Recent Apps Key (in the Touch Keys bar). A screen opens and displays a scrolling list of all of the apps that are currently open.
Tap the app you want to use or tap the Back Key (in the Touch Keys bar) to return to the current screen.
Swipe up or down to view the entire list of open apps.
Tap an app to use it.
Flick an app icon to the right or left to close the app and remove it from the list.
Navigation in the Recent apps screen depends on the device orientation. When held sideways, swipe left and right to view the entire list. Flick an app icon up or down off the screen to close the app and remove it from the list.
