Restarting, Resetting, and Repairing

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

Backing Up and Restoring Content

on page 41.

If your device fails to turn 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

Xperia™ Companion

on page 39.

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.

try restarting again.

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.
