Hello guys, I need your help.

Today, out of the blue, my wife's ION (lt28at) touchscreen stopped responding. The phone boots just fine (perhaps a bit slower than before, but that's my appreciation), messages are received, apps update automatically, but it doesn't respond to touch. How could it happened? we were just arriving home from a running workout, we were sitting on the porch and the phone rebooted on its own, after that it stopped responding to touch.

Now I've got a very sad wife, very little chance of getting a new device (the market in Venezuela is very restricted and limitative), and no clue as to how to fix it.

Please if any of you can help me here, it will be most appreciated.

Edit: Forgot to mention. the device has its bootloader locked. Firmware updated to ICS 6.1.C.1.111. Rooted (probably about 9 months ago).

Try taking a backup of data and re installing the software using Sony PC Companion.

Sorry for the lack of response. As suggested I tried to repair the firmware via Sony PC Companion. No success there. Looks like somehow its some piece of hardware malfuctioning.

I'm going to try to open the device and see if something is out of place. I'll post what happens then.
