Hello. There are two antenna cables in the p20 pro. What is the black one for? The one referred to in your diagram as the inter-board cable. What will happen if the connector onto the board where the connector for the black cable is next to the white cable comes off the board (the connector for the black cable)? I was trying to disconnect the black antenna (or inter-board) cable and the connect came off the board. I glued it back. Now my internet is slow sometimes but I'm not sure if it's my network or because the black cable may not be connected properly because I was scared to solder on the board.
These coaxial cables connect the modem portion on the main board to the external antenna circuits on the sub-board and housing. At the same time, the 3G and 4G signals are separated, so if one of the contacts is missing, some range will have poor network support and will constantly fail.
