I've seen this quite a bit after screen replacements. It always seems to happen if the housing of the particular iPhone is warped from being dropped, or the corners have been dented in from the impact of being dropped; even after using precision tools to rework the corners. Maybe there's uneven pressure being put onto the digitizer, due to the condition of the housing? I'm working with a guy at a metal fab shop on making a precision tool to correct warped housings, hoping this will correct a lot of issues.
 
Going as far as replacing the entire housing seems to correct the issue. In this case, most, if not all customers haven't come back with any issues of ghost writing.
 
I've also seen that oils from one's hands seem to trigger this, after a screen replacement... but I assume that this didn't occur with the original screen. Cleaning the screen of the oils would help a little, until you started touching the screen with your oily fingers again. If the housing is off by the slightest degree, perhaps the oils from youyour fingers could be the catalyst/trigger to the uneven sensitivity created by the housing.

I've also replaced the screen on several customers iPhones and suggested that they get a lifeproof case. None of these customers came back with these ghost writing issues after acquiring a lifeproof case. Maybe the oils being on the face of the lifeproof screen protector shield instead of the actual touch screen is helping with that?
 
Still working on a verifiable solution to the problem.
