I am not sure if it works, but when I put LCD screen back into connecter, touch digitizer no longer functioned and tried to replug it in multiple times, but unsuccessful. Also phone is IPhone 6s Plus 5.5 inch.
But couple days later after calming down, I was concerned that I hope I did not damage the touch digitizer connecter.
Here is image for zoom up, let me know if you can spot any damage into connecter or it its ok.

Digitizer works ok, but now getting new problem. Front camera and earpiece are not functioning well.
It does appear that the 4th pin in the lower row of the upper connector is a little bent. If you replaced the screen with a new one, you can hook up the old one as long as the touch worked on there to test it. Where did you buy the replacement screen from?
