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?

  • Here's some more info. In short: the touch sensors are too sensitive and trigger by themselves when the phone is hot. I found that updating to newer Sony firmware does a recalibration, best have your phone a little overheated when you upgrade and the recalibration is OK afterwards.

Your touch screen needs to replace now. Please contact nearest Sony Service Centre.
