Learn how to update software on your Sony Xperia Z1. Update your device to the most recent software version to get optimal performance and the latest enhancements. You can use the Update center application on your device to run a wireless update or you can use the PC Companion application on a computer to run an update using a USB cable connection.
If you update wirelessly, you can use either a mobile network or a Wi-Fi network connection. Make sure you back up and save all data stored on your device before you run an update.
