Personal data
Factory data reset Erases all of your personal data from internal phone storage, including information about your Google Account, any other accounts, your system and application data and settings, and any downloaded applications. Resetting the phone does not erase any system software updates you’ve downloaded or any files on your microSD card, such as music or photos. If you reset the phone in this way, you’re prompted to reenter the same kind of information as when you first started Android.
Storage
