Sony Xperia SP, T/TX and V seem to be having a very slim chance on getting Android 4.4.2 KitKat. Some Xperia Z devices are now receiving Android 4.4.4 KitKat while other models are getting certified with Android KitKat. Will Xperia SP, Xperia T, Xperia TX and Xperia V still get another major update?

Software Support Duration

Xperia SP, T/TX and V are facing the expiration dates of software support from Sony Mobile. Xperia SP was released on April 2013 with expiration date until October 2014 and so far, the smartphone has only received one major update after Android 4.1 Jelly Bean.

Unfortunately, Xperia T, TX and V have reached the 18-month software support expiration and if there is one lucky model - it would be Xperia V based on the expected end of life cycle.

Unlike Xperia SP, other three smartphones already received two major firmware upgrades from Android 4.0 Ice Cream Sandwich according to the official software support page from Sony Mobile. Xperia T/TX and Xperia V received Android 4.1 and Android 4.3 Jelly Bean within 18 months.

Never Announced for KitKat Upgrade Plan

Sony Mobile did not include Xperia SP, Xperia T/TX and Xperia V on the latest list of Android KitKat eligible devices. Android 4.4.2 KitKat was initially released to Xperia Z1, Xperia Z Ultra and Xperia Z1 Compact then followed through other Xperia Z devices.

Lately, Xperia Z1, Xperia Z Ultra and Xperia Z1 Compact received the final version of Android KitKat - 4.4.4 - rolling out in several territories worldwide. Now Xperia T2 Ultra and Xperia T2 Ultra Dual got the certification of Android KitKat firmware from PTCRB.

Here is the current list of devices on Android KitKat roadmap from Sony Mobile:

- Xperia Z1

- Xperia Z Ultra

- Xperia Z1 Compact

- Xperia Z

- Xperia ZL and ZR

- Xperia Tablet Z

- Xperia T2 Ultra

- Xperia E1

- Xperia M2

No Decisions Yet

Even though Sony Mobile already released Android KitKat for Xperia Z series and now pushing the latest Android 4.4.4 to selected models, the company remains quite on what will happen on Xperia SP.

Up to this date, Sony Xperia SP remains "under investigation" on receiving Android KitKat update along with Xperia T, Xperia TX and Xperia V.
