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 Backing up and restoring content on
page 141.
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
Computer Tools
on page 138.
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 force your device to restart
1
Press and hold down the power key .
2
In the menu that opens, tap
Restart
. The device restarts automatically.
To force the device to shut down
1
Open the cover for the nano SIM card and memory card slot.
2
Using the tip of a pen or a similar object, press and hold down the OFF button for
a few seconds.
3
After your device emits a series of three quick vibrations, release the OFF button.
The device turns off automatically.
Do not use overly sharp objects that could damage the OFF button.
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.
