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 123 .
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 sharing 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.

To perform a factory data reset
Before you start, make sure to back up any important data that is saved on the internal
memory of your device to a memory card or other non-internal memory. Factory data reset will
erase all data from your device's internal storage, and you will not be able to access the files
on any of your encrypted SD cards again.
To avoid permanent damage to your device, do not restart your device while a reset procedure
is underway.
