Running diagnostic tests on your device
The Xperia™ Diagnostics application can test a specific function or run a full
diagnostic test to check if your Xperia™ device is working properly.
Xperia™ Diagnostics can:
•
Assess potential hardware or software issues on your Xperia™ device.
•
Analyse how well applications perform on your device.
•
Log the number of dropped calls during the previous 10 days.
•
Identify installed software and provide useful details about your device.
The Xperia™ Diagnostics application is pre-installed on most Android™ devices from Sony. If
the Diagnostics option is not available under Settings [settings_label_launcher] > About phone [about_set-
tings<product="default">] or from the TOOLS [tools] menu in the Support application, you can download
a light version using the Play Store™ application.

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 64.
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 61.
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.
