Sony has just published the list of devices that will be getting the Android 4.3 Jelly Bean update that was announced yesterday. On the smartphone side, the company will be bringing the latest Jelly Bean version to the Xperia Z, Xperia ZL, Xperia ZR, Xperia SP and Xperia Z Ultra. The only tablet that is confirmed to get treated to the latest Android release at this point is the Xperia Tablet Z.
Sony is currently seeding the Jelly Bean 4.2 update for the Xperia Z and Xperia ZL. Starting from early August, the Xperia ZR and Xperia Tablet Z will get Android 4.2 as well.
Some older Xperia phones running Android 4.1 are still under examination. There’s a possibility that at least some of them will be updated straight to Android 4.3, but no names have been confirmed yet.
Additionally, Sony acknowledges that its updates haven’t been “as succinct or as timely as you might’ve expected.” The company’s developers have now changed their workflow to assure that future updates arrive faster. The whole procedure is detailed in a lengthy and educational blog post, in case you are interested.source
