The long screw on the top and the metal washer underneath it serves as the wifi conductive path, which connects with the top of the frame to form the wifi antenna. The RF cable at the bottom connects the cellular antenna to the logic board and there is a piece of flex cable on the speaker, screwed to the bottom frame to form the cellular antenna. make sure these parts are properly installed
