The easiest way to install a software update is to do it wirelessly from your device.
However, some updates are not available for wireless download. You then need to
use the Xperia™ Companion software on a PC or on an Apple
®
Mac
®
computer to
update your device.
Before updating your device, consider the following:
•
Ensure you have sufficient storage capacity before attempting to update.
•
If you are using a device with multiple users, you must log in as the owner, that is, the
primary user, to update the device.
•
System and application updates can present the features on your device in another
way than described in this User guide. The Android™ version might not be affected
after an update.

If no new software is available, it’s possible that you may not have enough free memory on
your device. If your Xperia™ device has less than 500 MB of free internal memory available,
you do not receive any information about new software. In this case you will receive a warning
in the Notification panel: Storage space running out. Some system functions may not work. If
you receive this notification, you must free up internal memory to get notifications about new
available software.
Updating your device wirelessly
Use the Software update application to update your device software wirelessly. The
updates you can download over a mobile network depend on your operator. It is
recommended to use a
Wi-Fi
network instead of a mobile network to download new
software so that you can avoid data traffic costs.
