Default Touch Screen Responsiveness While Charging

Hi guys,

I have a new XT1033 (Aussie dual sim version) Moto G.

When using the packaged charger, the screen becomes quite unresponsive. This seems to be a problem with a few other phones too. (Droid Incredible, GSII and Epic 4G all have threads on this problem.)

Why does this happen, and is there a fix?

Thanks,
Greg
