Replaced screen and Touch won't work

I replaced the screen and frame on a samsung A50, and while the phone lights up and displays perfectly the touch function doesn't work. I even tried another new screen and got the same issue. I checked all the connectors and all pins looks straight and clean.

Any thoughts on what the issue could be?

this is most likly because you did not properly plug back in the touch cable or a problem with cpu or traces on the board,

check the wire, then if that does not work, i dont know
