Sony is rolling out two new Android Lollipop builds for its Xperia Z3 series devices in select regions.

The build 23.1.A.0.726 is live for Xperia Z3 and Z3 Compact users from Russia, Latin America, the US, Turkey and the Middle East. Another build with version number 23.2.A.0.278 has been released for both handsets in Germany for subscribers, reports Xperiablog. The firmware is expected to be available for other countries across the globe soon.

Both the builds are based on Android Lollipop version 5.0.2, but not 5.1, which Google has released for its Nexus line-up.
