10.3.4 Backup & reset
Back up my data
Touch the switch to back up your phone’s settings and other
application data to Google servers. If you replace your phone, the
settings and data you’ve backed up will be restored onto the new
phone for the first time you sign in with your Google account. If you
mark 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 keyboard, and most of the settings that you configure in
the Settings application. If you unmark this option, you stop backing
up your settings, and any existing backups are deleted from Google
servers.

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
