KitKat now rolling out to Sony's Xperia Z Ultra, Z1 and Z1 Compact

An Android 4.4 KitKat update for the Xperia Z Ultra, Z1 and Z1 Compact is rolling out as of today, Sony's announced. 

In addition to what the newer OS version itself brings, Sony's folded in some tweaks of its own, like a reworked status bar and quick-settings menu, a couple of PS4-inspired UI elements, and updated forms of Sony's stock and media apps. While KitKat might be ready for this trio of devices, remember that availability depends on where you live and what carrier your handset may be bound to, so don't bet on a notification popping up this very afternoon. Sony confirmed back in November that the Xperia Z, ZL, ZR and Tablet Z, too, were eligible for a KitKat update, but they'll have to wait until at least "mid-Q2" for their snacks. In better news, the Xperia T2 Ultra, E1 and M2 have been added to that exclusive list, though we can't give you even vague timelines for when these updates might be available just yet. (engadget)
