And, to Kit Kat 4.4
Well, it seems by the beginning of next year, we might see Sony smartphones on Android 4.4. Honestly, I must say that Sony is now paying attention towards software updates, as in past they were criticized a lot for not updating their smartphones to the latest OS, even if it matches the requirements.
So Xperia users, are you happy?
