As you may know, once your Sony Xperia Z1s becomes eligible to receive the new firmware, you should be able to see a system update message in the notifications bar. Tap on it, choose download, wait until the download is completed, then choose install now. The smartphone will reboot and you should should be running Android 4.4.4 once the reboot is completed.

In case the Android 4.4.4 system update notification failed to appear you would also want to perform a manual check. In order to do so you must head to Settings > About phone > Software updates > Check for software updates. If this method doesn’t work either, it might mean that you will have to wait a few more days.
