I have been led to believe that there is a "cover "or "gasket "which goes over the proximity sensor. I have spent several hours on line trying to source this gasket but I have found no source for it. My research indicates that the proximity sensor will not function properly without this gasket. My own iPhone 5 is missing this gasket and the proximity sensor has very little range. I am desperately looking for a source for this part.
No, actually concentric is exactly correct. When the center of the circle in the ribbon is exactly over the center of the connector on the board the respective circles of the connector halves are CONCENTRIC and properly aligned.
