This is a known software issue from Sony.Everybody have this even I do.The only solution is to hope that 4.3 update will solve this.For now,there's absolutely no other solution for this.

Even I have been facing the same problem. 

Bought the handset 3 months ago, and have been taking rounds of the service centre since two months. Everytime I visit the centre, they format my phone or change some part, but I still face the same issue everytime.

The company refuses to give me a new handset and keeps changing one part or the other.

Really frustrated.Kindly help.
