Live with Walkman WT19i Camera focus not working fine after the latest update from android 2.3 to 4.0, getting poor quality images, tried many apps to from play store but still poor quality images.
If it doesn't work with either a third part app or the original camera app I'd recommend you to try performing a repair of your phone's software.
You can easily perform it with our program Sony PC Companion, availalbe for download from the link below.

Thanx for your reply Sir but I have repaired my phone already once. I think i have to downgrade it to android 2.3, is this possible if yes how and without rooting the phone.
I am aslo facing some problem in LWW after ICS update .587.
Poor performance of Camera as mentioned above even afater repair.
I am also facing a problem to connect internet, After a restart phone goes to 3G setting WCDMA/GSM, even I set to GSM only. If 3G network is not available, I cannot connect to internet, Only when 3G network availaable I able to connect internet (Here is some 3G network problem indoor).
Why Sony provide Repair option with a selection of update i.e. GB, ICS .431 , .587 so on. So that user can do the repair within PCC or SU itself and no need to go for Flashing, Rooting (such a long process).
