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, 
(System update icon) 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.
- If you are using a device with multiple users, you must log in as the owner, that is, the primary user.
- 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.
To check for new software
- If you are using a device with multiple users, make sure you are logged in as the owner.
- Find and tap Settings > System > Advanced > Software update.
Updating your device wirelessly
