Sony has been rolling out Lollipop updates left and right to its Xperia Z series devices for many weeks now. Multiple generations of the company's flagship line have so far been upgraded to Android 5.0, and today the time has finally come for the T-Mobile-exclusive Xperia Z1s to receive the same treatment.
The update to Android 5.0.2 Lollipop is now rolling out over-the-air for this device, with the new software having build number 14.5.B.0.236, as evidenced by the image below.
As always in these cases, the rollout is going to be staged over the next few days or weeks, so it may still be a while before your particular handset notifies you about the update.
Though no matter how long it takes, at least it's now on its way. And of course you can manually check for it by choosing the relevant option in your phone's Settings menu.
The Lollipop update brings with it the new Material Design UI, new Xperia wallpapers, themes, a new media app, the revamped lockscreen and notification drawer, along with the usual performance improvements.
