Sony Xperia smartphone with Android Jelly Bean

Soon after the official unveiling of Android KitKat OS last week, Sony had vowed to announce its rollout plans of the new OS update for its Xperia phones.

Staying true to its words, Sony has detailed the list of Xperia models slated for Android v4.4 KitKat as well as v4.3 Jelly Bean in its blog. The company would first push v4.3 update to Xperia Z, Xperia ZL, Xperia ZR, Xperia Tablet Z, Xperia SP, Xperia Z ultra and Xperia Z1 starting next month.

That's not all; Sony has also decided to skip the v4.2 update directly to v4.3 for three 2012 models - Xperia T, Xperia TX and Xperia V, in December. Since the OS rollout is carried out in phased manner, some regions may have to wait a little longer to receive the update.

Sony, though not defining any timeline, has confirmed that the new v4.4 KitKat firmware will be released to the company's select (five) marquee devices, which include Xperia Z, Xperia ZL, Xperia Tablet Z, Xperia Z Ultra and Xperia Z1. Sony has asked fans to follow its tweeter feed @SonyMobileNews for updates on firmware features and their release date details.
