Restarting and resetting your device

You can force your device to restart or shut down if it stops responding or won't
restart normally. No settings or personal data get deleted.
You can also reset your device to its original factory settings. This action is
sometimes necessary if your device stops functioning properly, but note that if you
want to keep any important data, you should first back up this data to a memory card
or other non-internal memory. For more information, see
content on page 124.
