I have problems with the touch screen of my xperia sola, i bought my phone 3 months back and it was doing good until all of a sudden, the touch sensitivity is all lost and i cant even open the lock. i have tried to repair the phone software and also upgrade the software but it does not help in anyway. Please reply of what the problem is and a solving solution to it. its been so annoying to use the phone, i cant even receive any phone calls i get.
Unfortunately given the problem and what you have done to try and resolve this, I can only advise that you return the phone so that it may be assessed by an authorised repair agent.

Go to the nearest auth. service center and ask for repair, It might be a hardware fault 
thank you for the reply. I will try solving it through a authorised service center
Why don't you put your cell phone in direct sunlight? Say around for an hour or so with the touch screen facing the sun.
P.S. Doing this has helped out some people and you might find it helpful as well. Otherwise visiting the service center is the best solution.
