Updating Your Device
You should update the software on your device to get the latest functionality,
enhancements, and bug fixes in order to ensure optimal performance. When a software
update is available, appears in the status bar. You can also check for new updates
manually, or schedule an update.
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.
