Ok driving me crazy, what are the contact points for?

got a picture - so I don't have to take my phone apart? Otherwise I will.

I remember that there were 4 I think that looked like it was to the antenna that is around the camera bump on the back cover. I think that might be the main LTE antenna but I could be wrong.

I suspect one of those sets might be fore wireless charging if they were to build a new back panel for it. I think it might have gotten canceled with the issues on the samsung wireless quick charging.

Not sure about others but they might be test ports for when the phone is made - and then retained for any repair work. IE if oyu needed to check it internally bypassing the USB-C port and charge circuit. etc etc.
