This update should solve the “flickering” screen and minilag. It’s just a guess, I realized with a support forum sony.

For me 4.3 is almost perfect. Except : extremely low battery life (~90 hrs uptime without usage+perfect GSM coverage ,configured to fully “offline” ) and sometimes minor minilags.

I’ve been running the 12.1.a.1.205 update for the past few days with no issues, flickering screen fixed, lag has completely gone and no crashes or freezing at all, i recommend everyone install this update as soon as possible to fix their xperia sp from the problems caused by previous updates. Thanks sony it looks like you got it right this time. 🙂
