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.
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.

1 If you are using a device with multiple users, make sure you are logged in as the
owner.
2 From your Home screen, tap
.
3 Find and tap Settings > About phone > Software 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 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

updates you can download over a cellphone network depend on your service provider.
It is recommended to use a Wi-Fi network instead of a cellphone network to download
new software so you can avoid data traffic costs.
