7. Using a microSD Card

Pictures, music and video files, can be saved to external memory. Before saving
these files to external memory, you need to insert a microSD card. If you have
not inserted a microSD card, your items will be saved to internal memory.
Warning! Do not remove the microSD card without unmounting it first.
Otherwise, it may damage the microSD card as well as your phone, and the data
stored on the microSD card may be corrupted. To unmount the microSD card,
from the Home screen, tap the Menu Key
tab > Storage > Unmount SD card.

8. Connecting Your Phone to a Computer via USB

1 Use the USB cable that was provided with your phone to connect the
phone to a USB port on your computer. You'll receive a notification that the
USB is connected and can see USB connection type pop-up.
2 Tap Media sync (MTP) to confirm that you want to transfer files between
your phone's microSD card and the computer.
When the phone is connected as USB storage, you receive a notification. Your
phone's microSD card is installed as a drive on your computer. You can now
copy files to and from the microSD card.

9. Opening and Switching Applications

Multi-tasking is easy with Android because you can keep more than one
application running at the same time. There's no need to quit an application
before opening another. Use and switch between several open applications.
Android manages each application, stopping and starting them as needed to
ensure that idle applications don't consume resources unnecessarily.
