After ICS, Touch screen is not working when mobile is overheated I have Sony Xperia Mini pro, i recently updated it to ICS. But now when the phone is overheated (especially during recharging). The touch screen becomes unresponsive, even if i restart my phone, it stills that way. 

It goes back to normal by itself after some period of time. 

What should I do to fix the problem?
Your touch screen needs to replace now. Please contact nearest Sony Service Centre.
