What is this on the motherboard that broke?

There is this “ground pin” look a like, that broke of the motherboard, and I do not know what it is. I tried to solder it, but the bottom of the “pin” just came lose. Will the device function without it, and what part will lose functionality? It connects to the midframe of the galaxy.

Can I connect that “ground pin” directly to the side of the resistor?

In the schematic it says ANT4003, does it connect to the top part of C4047?

Part code 3712-001564 , related to BT/WIFI. How to fix this nightmare?

You'd need the solder skills of a super genius to attempt fixing that... Try following the schematic to whatever component that lead goes to (nearby or flipside), then solder a wire to that and connect to the frame

If you wanna fix it, you’re going to want to find someone who is skilled in microsoldering. I’m looking at the teardown on ifixit and it looks like it’s just a grounding pin. With there being multiple ground points in these phones, you should be able to get away without it.

I managed to superglue one side of the ANT4003 onto the motherboard so it would stay where it should be, and the other end I soldered to the C4047, since it looks like it’s connected to it.
