How to Install software update on smartphones via OTA [Over-The-Air]:

If Xperia Z series device owners are getting the update notifications, they must select "Yes, Download" option. After downloading, select >> "Install now". The phone will restart automatically and the OS will be updated to the new version.

We would like to remind our readers that the roll-out process is carried out in phases, so it will take some time to reach all corners of the world.

Until then, users can check manually on the smartphone by going to 'Settings' >> 'About phone' >> 'System update' >> 'Check Now'.
