Android 4.4.4 is now available to Xperia Z1 owners on T-Mobile’s network. The new software push moves the handset’s build number to 14.4.B.0.37 and adds a few cosmetic changes, along with support for Sony’s SmartBand SWR10 and Lifelog app.
If you’re unfamiliar with KitKat’s enhancements, the Z1 will now feature a transparent navigation bar, new boot animations and refreshed themes. The new software also ships with stability improvements, as well as enhancements for WiFi and network-based phone calls. The update is rolling out as an over-the-air push, however you should be able to manually start the process from within your phone’s settings.
