My iPad is masturbating!

As I have read the New York Times or Kindle Apps on my iPad over the past few weeks, the tablet has seemed to take on a mind of its own, opening articles or turning pages when I haven't touched it. Going by a techie store I am asked whether the screen has ever been broken and replaced, and indeed, this happened several months ago. It appears that if the job isn't done properly, or the screen is a poor quality one, it can start spontaneous touching or stroking in the absence of a human finger. To turn pages I am now gingerly stroking parts of the screen that don't seem to get its g-spots excited..... (I don't want to buy a new iPad because I am waiting for the larger one to come out, it will be more useful for displaying musical scores.)
