Whenever I plug in the USB cable to connect to my computer, the touchscreen behaves very erratically, making it very difficult to swipe properly, like flipping homescreens. To prove this, I ran a picture drawing app, and it shows my touch going everywhere and not responding as it should be. This only happens when plugged into a computer, and the USB is set to one of the options (like SD card management) and not to 'none'. Also does not happen when just plugged in for power charging. Anyone experience this also? I'm on 2.0.
