The Android 4.3, JellyBean update for the Sony Xperia T, Xperia TX, Xperia V and Xperia SP will start rolling out at the end of Jan.
Sony announced the news via Twitter earlier today.
"We hear you re: JB 4.3 for Xperia T, TX, V, SP- we're making final preps & will start rolling from end Jan/ early Feb.," tweeted the company.
Sony made good on its promise to have software updates out for most of its devices in a short amount of time. The only device on this list confirmed to receive Android 4.4 at this time is the Xperia SP. The Xperia T and TX are currently being investigated for the possibility of an official KitKat update.
The Android 4.3 JellyBean update also recently rolled out for the Sony Xperia Z, Xperia ZL, Xpera ZQ and Xperia Tab Z.
The new software brings various improvements to these devices including a slightly updated UI, updates to Sony native apps and the addition of the Sony Smart Social camera. An updated version of Stamina mode is also now available and gives users new options to extend their battery life.
This same update rolled out for the Xperia Z1 and Z Ultra last month.
The Android 4.4 KitKat update is now available for several Sony devices including the Xperia Z, Xperia ZL, Xperia ZR, Xperia Tablet Z, Xperia T and Xperia V in the form of a new ROM.
A group of developers known as the FreeXperia team released unofficial KitKat builds of CyanogenMod 11 for all of these Sony Xperia devices this week. They are also working on upgrades for the Xperia Z1 and Xperia Z Ultra.
The official CyanogenMod 11 build is still not available. These unofficial versions are potentially unreliable at this time so they should be downloaded and installed with caution.
