I didn't believe my daughter until she took a video of the occurance.
Here's what happens...
She plugs her iPod into the wall charger.
Just before the iPod seems to be manuvered by someone else, it becomes inaccessible to her. (it doesn't respond to her touch)
Next, without anyone touching the screen, apps such as gmail are being clicked on and they are going into her contacts. They went into her Instagram account and clicked on her pictures.
They also played a game...
So, do you still think the charger is causing the iPod to 'think areas of the screen are being physically pressed'?
((I'm not trying to be argumentative, but please don't say 'not possible' when you haven't seen it...))
