Step 7 shows an antenna plastic near the top of the phone and Step 8 shows the two coax that run to the bottom of the handset. Looks like part of that plastic antenna shown in Step 7 near the top is for BT/Wifi on the button side of the PCB, then there are 4 antennas on the other side of the board (two coax, two gold contacts up to that plastic antenna part). I’m wondering if there is any indicators what antennas are used for what inside the handset. Thoughts?
