Re-attaching this cable is the only tricky part to replacing the battery on my 6+. It had a bow on the middle that I had to flatten out before pressing the connector on with finger first on one edge and then on the other. I had white tire tracks on the screen and no touch screen until I connected it correctly. The front has to rest in just the right place on the back while attaching this thing so the cables aren’t strained the front doesn’t fall down. Small fingers would be a plus at this step.
