Chosen Solution

I would like to identify a broken flex in the upper right, just to the left of the rear camera. There are 4 snap connectors here…..this one that I have broken, then 2 others and then the rear camera (extreme right). It’s the smallest of these flex connectors and I’d like to identify it to test the operation and to order a replacement. In the photos the red spot is visible where the connector has started to separate. Can anyone help please ?

Take a photo of it and post it here. Adding images to an existing question

I realize this is five years too late, but for anyone else who comes across this, this cable is the right LTE/cellular antenna connector. It is grafted to the black module along the top of the device between the rear and front cameras, and connects to the logic board via a small coaxial connector.
