Replace S5 active charging port, difference between G870A and G870F? - AT&T Samsung Galaxy S 5

I'm about to replace the port to hopefully get my mic working again, but when I should install it I noticed that one of the connectors is missing on the A board. And the F-board is nowhere to find. Anybody knows what this connector is for, I'll guess it's for an antenna for a different band?

Ok, I just transplanted the circuit from the old F-board over, and everything seems to work ok, and the mic is working again!

Has anyone with the VZW note 2 used one of these adapters instead of hacking up their phone and soldering in connectors? Just looking for some input on if this works well or not? Thanks.

Dude you are going to need some ninja soldering skills. Better take it to a service center if the connector on the Motherboard is broken.

Motherboard labels/functions?

Looking to see if anyone knows what the function of this part of the motherboard is? It snapped off when I was replacing my battery and so far the only issue I'm having is spotty GPS, but I don't know if it's related. Anyone have a diagram of the motherboard with functions of the various parts. See photo for the part I'm talking about. It's the top right corner as viewed from the back of the phone. Thanks!
