signal failure/ issues after charger port replacement

I’ve noticed this after doing several charger port replacements,sometimes swapping out the antennas fixes the issue( or using a port from another phone fixed it too), some times it’s intermittently and sometimes it’s just drops bars then gets it back, idk just wanted to see if it’s a common issues with this type of repair or a QA problem, Im a pretty decent tech I have 6 years of experience repairing phones but this is something that has eluded me.

Did you follow this guide Samsung Galaxy S22 Ultra USB-C-Anschluss und Ladeplatine tauschen?

What's not to obvious is this board also connects to the frame embedded antennas via four prongs. The landing pads within the antennas may need cleaning as the exact alignment of the boards pins may not intersect with the original spots so corrosion or debris get in the way, in addition the mount points are also active here tying the board to the frames chassis ground so the screws, stud's and board exposed metal surrounds are clean so they offer good electrical pathing as well.

Lastly, make sure the ribbon cables and there connectors aren't damaged.
