Hi !
Ok bought my phone back in december 2011. After a week I realize that the phone have an issue regarding captive buttons. The buttons start to work itself when the temperature raise to 38 degrees. And this happened always after talking about 15 minutes .
Ok I took my phone to the service centre. they have repaired it , I have to install all the aplications again, but the phone seems to work ok.
The calibration fix was done. Now after a couple of months , the issue started again. The summer is here so the problem.
I noticed that the captive buttons started to working itself when the temperature raise to 42 degree.
Today i was out and not to the sun. the phone was about 39 degrees celzius and become useless. I did not even working on it.
I tried to use it and cant make a call. The buttons started to act itself like when you press on it.
So the point is that the calibration fix will not completely remove the problem. I am very disapointed that I have choose the Sony phone.
I didn't know for this issue, I did not immagine that the Sony could even trow on the market a phone that have an issue from the production 
I am waiting to ICS to see if the issue is resolved there, but i doubt. And the ICS have so many problems (poor photo quality and other issues reported here, but it seems that I will have to take a risk.
The service support told me that I could send the phone back to the service to repair it again. If nothing works they could give me a new one. But who can assure that the new one will be issue free ? There are so many people here complaining of the same issue.
I could root it and run the script reported on many sites, but this could lead to loosing warranty and I don't want that.
If the problem could be solved by running some kind of script, i dont know why Sony didn't make some update while they know about this problem !
