If old and new screen are showing the exact same issue, odds are the drop that cracked the screen caused damage somewhere else on the board or someone trying to fix it caused pry or other damage.
 
I'd start by examining the whole board using 20x or more magnification for traces of damage mechanical (I mean things seem broken damaged, missing, or part removed from the board) and possibly liquid damage.
 
EDIT: had this same exact issue and have seen it all over the place with other repair businesses. This issue is due to theever more recurring. We are encountering a lot of touch circuit being damaged, primarily the touch connectorissues: intermittent or permanent loss of touch, accompanied with flickering on the boardtop of the screen, and sometimes other visual artifacts on the screen.
To fix this issue permanently, we are replacing one or both
the touch IC. Reflowing/reballing those 2 fixed itcontrollers AKA touch ICs. This often occurs after a drop, a bent in ALL the cases encountered so far. Not to say that there could be other causes. I did it myself in two different caseshousing, sometimes after a screen crack and succeeded in getting ridsometimes without any evidence of drop on the issuephone housing.
