A little late to the Android 4.4 KitKat upgrading party compared to Samsung, HTC or LG, Sony is apparently bringing no less than three of its smartphones up to date software-wise over the next few weeks.

Shame on Sony for needing nearly five months to deliver its first official over-the-air KitKat update, but kudos to the Xperia makers for getting the ball rolling alternatively on the Xperia Z1, Z Ultra and Z1 Compact.

Technically, users of the three high-end gadgets should receive a notification message any minute now. In reality, you may need to wait an additional few days, perhaps even weeks, depending on where you live.

But it’s happening, and this is no time to complain. According to a Sony Mobile blog post, the fresh firmwares shall bear standard 4.4 UI tweaks and performance optimizations, as well as a rehashed, more intuitive Status Bar and Quick Settings menu, an overhaul of Sony-specific apps like MyXperia, Smart Connect, Small apps, Walkman and Sony Select, plus a new custom interface experience called Xperia Themes.

In a nutshell, if you’re the least bit familiar with Xperia Z2’s native user interface, you know what’s coming. A generalized software revamp that’s in no way radical, but in every way sweet and silky smooth.

Pretty much as soon as the Z1 – Z Ultra – Z1 Compact trio is done with being updated, the Xperia Z, ZL, Xperia Tablet Z and Xperia ZR are themselves to take things to the next level. The quartet’s KitKat ETA is mid-Q2, so around May 15, and the Xperia T2 Ultra, E1 and M2 are reportedly next in line.

When? Sony doesn’t say, but my guesstimate is July. Best case scenario. Granted, they’re all young bucks, having seen daylight earlier this year, yet they can’t hope to outrank veterans Z or ZL with their mid-range or, in the case of the E1, low-end hardware.
