Is the phone on iOS 11? There are lot's of folks complaining about strange issues with the iPhone 6S and iSO 11. The worst case is when Touch fails completely. I wrote up an article on this; you can go to my profile for a link if your curious. Seeing as how your replacement screen is a refurbished original, it should have a proper Touch controller on the flex. That said, I would try another screen to see if the issue persists.
