Severe lag

[Displeased]

I've been facing severe lag after a software update to 4.3 using Sony PC companion, the day after I bought my phone. Contact list is empty, applications force close, applications are taking time to respond. Just one day and all this! I need a solution.

I have already tried that, but in vein. The screen flickers at times, too. Am I gonna have to live with this, Sony?

Sorry to hear that.As the problem still exists you have two options...Either wait for the next bug fix update or visit a Sony Service Center to have your phone checked and fixed...

I guess I'm going with the later. Thank you all for your support.
