    Why hasn't my device received an update yet?

    • 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 (device memory) available, you do not receive any information about new software. The following notification appears in the Notification panel to warn of the lack of storage space: Storage space running out. Some system functions may not work. If you receive this notification, you must free up internal memory (device memory) before you can get notifications about new software being available.
    • Software updates are released at different times depending on the operator, market, region or country. Therefore, we cannot give you an exact date for when a specific update will be available for your device. In addition, network operators and specific markets may choose not to avail of the updates for specific models.
