Factory Data Reset

You can reset your device to factory defaults, erasing all data from
your device.
This action permanently erases ALL data from the device, including
Google or other account settings, system and application data and
settings, downloaded applications, as well as your music, photos,
videos, and other files. Any data stored on an external SD card is not
affected.
Note: When you sign in to a Google Account on your device, Factory
Reset Protection is activated. This protects your device in the event it
is lost or stolen. For more information, see "Factory Reset Protection" on
page 14.
If you reset your device to factory default settings with the Factory
Reset Protection (FRP) feature activated, you must enter the user
name and password for a registered Google Account to regain access
to the device. You will not be able to access the device without the
correct credentials.
