MULTI-TASKING AND THE TASKS KEY
Run multiple applications simultaneously: Press the Home key from
any application to return to the home screen then launch another app.
The original application will be suspended until you return to it.
Press the Tasks key to view recent apps, double tap on the tasks
key to toggle between the two most recent apps.
TIPS
If you are finished with an application use the Back key to exit the
application. If you leave applications running in the background the
system memory will be consumed and the device will become slow to
respond. Return to the app and close it, or from the Home screen press
the tasks key then press ‘Clear All’ to shut down any unescessary
apps and processes.
