Does anyone know what the cables on the bottom of the logic board are for on and I phone s 6 plus? Their are two of them that run along the side of the board on the SIM card side that are not visible unless you remove the board and turn it over. Thanks

I don’t see the question. If you are asking what they are for, they are for cellular diversity and GPS.

@cray lets clarify what phone you are talking about. An iPhone 6Plus or a Samsung Galaxy S6? The only cables that you would have running along that area on an iPhone are the antenna cables. Check this teardown for the cables. Just in case you are referring to an iPhone 6s Plus check this teardown.
