Sony has begun rolling out its Android 5.1 Lollipop update for the Xperia Z1, Xperia Z1 Compact, and Z Ultra.

This release brings camera improvements, SmartWear integration, a fix for the dreaded Stagefright vulnerability, and lots more.

The release comes with build number “14.6.A.0.368,” and it’s rolling out now to the devices listed above in a small number of markets, according to XperiaBlog. The software is expected to expand its reach to more users in more markets over the coming weeks.

You can download and install the update directly on your device — you’ll get a notification as soon as it’s available — or via Sony’s PC Companion software. This is the same update that has previously rolled out to more recent Xperia handsets.

Unlike previous releases, however, this one includes a Stagefight fix, ensuring your Xperia isn’t vulnerable to attack.
