Restarting and resetting your device

You can force your device to restart or shut down in situations where 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 have to first back up this data to a memory
card or other non-internal memory. For more information, see
restoring content on page 135 .
If your device fails to power on or you want to reset your device's software, you can
use Xperia™ Companion to repair your device. For more information on using
Xperia™ Companion, see
Your device may fail to restart if the battery level is low. Connect your device to a charger and
try restarting again.
If you are using a device with multiple users, you may need to log in as the owner, that is, the
primary user, to reset your device to its original factory settings.
