Sony is now rolling out the update to Android 5.1.1 Lollipop for three of its smartphones - the Xperia Z1, Xperia Z1 Compact, and Xperia Z Ultra. This follows a similar rollout which made its way to the Xperia Z, Xperia ZL, Xperia ZR, and Xperia Tablet Z last week.
The devices getting it this time around are basically successors of sorts to that particular series. They're also quite old, which makes the fact that Sony is still supporting them even now an interesting fact.
For all three handsets, after applying the update you will be on build number 14.6.A.0.368. Currently the new software is live in only a few regions, but it's expected to spread across the world in the coming days and weeks.
The update fixes the famous Stagefright vulnerability, adds additional options for Wi-Fi and Bluetooth in the notification menu, has new themes and Settings icons, integrates LinkedIn with your Calendar and Contacts, and improves camera focus, speed, and accuracy.
Additionally, you get improvements to volume and silent mode control, new Xperia for Business features, instant calendar events (shareable from email), calendar agenda in Email, and you can use the Sony SmartWatch 3 as a remote shutter button for your camera.
Pls upgrade xperia Z1 to LTE (4G). Thank you.
