Sony Mobile has detailed plans to upgrade a number of Xperia handsets to Android 4.3, but so far we are still awaiting official timing details. French operator Free Mobile may have given the first hint, pointing to a December 2013 timeline for the Xperia SP’s Android 4.3 update.
It looks like the Xperia SP will be one of the handsets that moves directly from Android 4.1.2 to Android 4.3, as there has been no Android 4.2.2 update until now. The likelihood is that the flagship Xperia Z series will see the update to Android 4.3 before the Xperia SP, so we may end up seeing the v4.3 update land even before December. All of this is speculation though, so we’ll keep you posted when we have any concrete dates.
