The only 2012 Sony Xperia handsets that have been promised a future upgrade by Sony are the Sony Xperia T, TX and V. This is the Android 4.3 update that is expected to land at some point next month. There is no confirmation that these handsets will officially get Android 4.4 KitKat, although it appears Sony is working on it.
However, spare a thought for those running other 2012 Sony Xperia handsets, where it looks like no further Android updates are coming. Well even if there aren’t any official updates coming, you can always rely on the talented developers who do their best to keep older hardware updated with the latest software.
A case in point is the Novathor-powered Xperia models including the Xperia go, P, sola and U. A number of devs over at XDA such as munjeni, percy_g2 and Gava97 have created unofficial ports of CyanogenMod 11 (Android 4.4) to run on the above handsets. They are still ironing out some issues such as Bluetooth not working, but progress is coming on very quickly. If you’ve like to find out more click through links below. You can also check out some videos of each ROM (in Czech) to see how they run.
Thanks Ben, Bhushan and daffu!
