Sony is now rolling out the Lollipop OTA for the Xperia Z1 and Z Ultra in the US

If you’re the proud owner of either an Xperia Z1 or Z Ultra and reside in the United States, you may want to listen up, as Sony has just started rolling out the long-awaited Android 5.1. update for both handsets in the region. In terms of added functionality, the upgrade brings the latest build of the open-source operating system, as well as a multitude of bug fixes, stability improvements and speed optimizations, including a fix for the ever-so-scary Stagefright vulnerability.

All the changes you’d expect to find in the Lollipop software are bundled into this upgrade, which has build number 14.6.A.0.368 attached, such as support for multiple accounts, improved notifications, stronger 256-bit encryption, a smoother multitasking experience, refined unlocking methods, streamlined performance, increased battery life and, of course,  Material Design.

As is the norm, the update is being rolled out in stages, but if you don’t feel like waiting for a notification confirming that it’s ready for your device to hit your unit, you could always search for the upgrade manually. To do so, open the Settings app, scroll to the bottom and tap on “About Device”, hit “System Updates”, then select “Check for updates”.
