Sony has announced that Xperia T, TX and V is not going to get Android 4.4. Kitkat. It’s not like that Sony is not providing the updates but it seems the above devices are out of luck. In past few months many devices have been updated to Android 4.4. Kitkat by Sony.
Sony Xperia T. TX and V were launched with Android 4.0 Ice Cream Sandwich and later received update to Jelly Been. Few months earlier, devices status were “Under Investigation for Android 4.4 (KitKat)” but a change has been made which confirms that there won’t be any more updates for these devices. Android 4.3 Jelly Bean is listed as the “latest & final version” for Xperia T, Xperia TX and the Xperia V.
So, it’s quite bad for the users of these device but we hope other Xperia Devices will be getting the Kitkat soon or already have been running Kitkat.
