One of this year’s Xperias that was left out was the Xperia SP. But fret not, SP users, as it appears that Android 4.3 for your handset is coming very soon.
A new firmware build (12.1.A.0.253) fort he SP was certified just two days ago, and XperiaBlog reports that this should be an Android 4.3 build. Moreover, an XDA user from Hungary, who seems to be an official beta tester for Sony, recently posted a screenshot showing that 4.3 Jelly Bean is already running on his Xperia SP.
It’s expected that all versions of the Xperia SP (C5302, C5303 and C5306) will be updated to 4.3, although exact timing will probably depend on carrier and country.
As reported back in November, the Xperia SP should also get Android 4.4 KitKat, but only starting 2014.
