Yesterday we saw Sony tweeting regarding an ETA for android 4.3 roll out on Xperia SP at the end of Jan or in early Feb 2014 after two android 4.3 firmwares were already certified on PTCRB from which one was removed later. Well it seems now another new Android 4.3 12.1.A.0.263 firmware is certified on PTCRB page and we hope it is the final build of which Sony mentioned in tweet.

Android 4.3 12.1.A.0.263 firmware is certified for all Xperia SP variants C5302 / C5303 / C5306, this would be the third build to get certify; first being 12.1.A.0.253 firmware and second being 12.1.A.0.256 firmware from which we saw leaked 12.1.A.0.253 firmware ROM revealing what Sony has planned for Xperia SP users on android 4.3.
