Question
How do I perform a
Factory data reset?
Answer
• Resetting the phone does not erase
any system software updates you have
downloaded or any files on your microSD
card such as music or photos. And so, if
you want to erase all the data on the SD
card while resetting the phone, select the
check box of Erase SD card.
