You can search for the latest available software to update, and then if you want, you can start the update process by following the installation instruction. When the download is finished, the phone will automatically restart and your phone is updated with the latest software. If there is no newer version to download, the message 'Your phone already has the latest software' is displayed.
Note: You can only perform a software update when new software is available. Updates are released at different times depending on your phone model and operator.
