Touch problems while charging

[kiranak]

When ever i connect my phone to the charger or usb the phones touch screen responds haphazardly.

keyboard has a lot of issues whenever i press a single key mutiple characters gets pressed and it is very annoying.

Gave the phone twice for service at the service center the problem still persists and also did software repair on the PC companion.

So wat could the issue be ?

its been like only 3 months since i bought this phone already have problems with it.

will replacing the display screen fix the isue ?

Have you tried charging this from another socket to see if this issue persists or see if the issue persists when you charge via the PC?

I tried charging it with different sony cable and all the wall socket in my place,The problem still persists.

when connected to the pc the problem is the same and even with laptops.

Its been only three months since i have bought the phone and half the time its with the service center and i have feeling that i made a big mistake by buying this phone.

I have problems with certain chargers. The charger that came with my phone works fine and the one from the nexus 7 also, but a non-brand creates the same problems as you have. Try changing the charger...

Do you have any battery related apps installed? Battery savers, superfancy widgets... anything battery related?

Im out of ideas. This sounds like a hardware problem with the phone..

[kiranak]

i have got it checked thrice !

they said that my power lines are faulty and no problem with the hardware.

I'd try to remove them. When you put the phone on the charger, they do certain things. Maybe one of them eats up the CPU capacity with animations or whatever. It can cause funny things on the keyboard which is also can be a big CPU-time eater on it's own (predictions, learning words, etc). I'd remove them on-by-one, starting with the widget.
