Factory data reset
Phone reset will erase all of your personal data from internal phone storage,
including information about your Google Account, any other accounts,
your system and application 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 mark the checkbox - Reserve the content of Phone storageII before
touching Reset phone, any files stored on your phone’s storage will not
be erased. If you reset the phone in this way, you’re prompted to re-enter
the same kind of information as when you first started Android.
When you are unable to power on your phone, there is another way to
perform a factory data reset by using hardware keys. Press the Volume
up key and the power key at same time until the screen lights up.

this option, a wide variety of settings and data are backed up, including
your Wi-Fi passwords, bookmarks, a list of the applications you’ve
installed, the words you’ve added to the dictionary used by the onscreen
