We’ve been informed by a handful of our readers that T-Mobile is finally rolling out Android Lollipop software updates for the Sony Xperia Z1S. Although T-Mobile’s software updates page still indicates that it is in “T-Mobile Testing”, the device’s own individual page does contain details of the update. Specifically, it’s Android 5.0.2 and weighs in at over 640MB in size. It also comes with Group messaging support.

From today, you should be notified that an over-the-air update is available to download. If you don’t, check in your settings menu and you should find it once you check for updates manually.

Customers are advised to ensure they have enough space and at least 50% battery remaining before updating via Wi-Fi or through the PC Software. As always, let us know if you get it downloaded successfully and be sure to send us screen shots to show us how it looks on the older generation Sony device.

Thanks to all who emailed/tweet us with this news.
