mine is  6.0.b.3.184,  i updated to this version recently.( after facing the the issue)

[Bardia]

Oh man,it's a bad news.i thought it because of .184 ... so it means it's a hardware problem

Touch responce is experiencing laggs. As per my research, since touch-screen CMOS pannel is not dead for particular point (no consistancy with failure to understand the touch at any particular part of the screen), there must be some processing lag. To confirm the processing lag, I set my phone to a live wallpaper and attempted swipes of home screen -

- The transition of home screens is not subtle

- The swipe/touch fails to respond if there are successive attempts within 1 second

- Same problem occurs while typing with on-screen keyboard (both portrait and landscape)

On contacting the service centre regarding this issue they suggested f/w upgrade, since there's no such upgrade available at the moment, I tried repair phone option. After repairing my phone 3 times, I think I shall wait for ICS; since I am pretty sure, Sony will not claim any hw issue with this...

I hope ICS can fix this
