Touch problem while charging through USB on computer

DanneLeo — Fri, 13 Sep 2013 14:05:20 GMT

Everytime when I plug in my phone through USB cable to my ACER laptop, the touch does not respond when using the phone, even though I used the original USB cable that is provided with the phone. And I've sent my phone to the repair center because of the same issue. But the problem still persist. But when I use my brothers laptop which is different model as mine, the touch respons flawlessly. I NEED HELP HERE

I assure you its not the phone but the source of power due to the fact it works flawlessly on another device but not perfectly with your acer laptop

I also experienced the same thing, but the problem occurs when I connect the charger to the power source, also to the laptop that is connected to the power source.
There is now the latest update, hopefully it can eliminate this problem.

If this also happens when you charge the phone using the original charger i recommend that you first try making a repair of the phones software in PC Companion. If that doesn't help the phone needs to be calibrated by an authorized service location. Contact your local support (http://www.sonymobile.com/global-en/support/contact-us/) or a service location for assistance in that case.

If it only happens when charging from a certain device it might be a problem with grounding or power supply from that device.
