This is a problem that comes up every once in a while. Before and after I rooted my hydro. All of a sudden the touch screen will not respond well to my touch while charging. If I touch in one spot it will do something different. As if the sensors are not calibrated. But, either way, it does not happen often. Just curious to know why it does that and only while on the charger. To get rid of the problem I unplug the charger and everything is fine. I have to turn the phone off for a few minutes and back on. Sometimes I remove the battery for a few seconds.
