Cell antennae signal weak
So the Lightning connector went bad (unable to charge when plugged in) so I had a local shop repair it. After that, it seemed as though the phone had a hard time acquiring a cell signal but I couldn't pinpoint the blame on the repair shop.
Question: Is it possible that an antenna connector/connection was left loose? If so, does anyone have a picture of the antennas that control that? If needed to replace, would I replace the logics board? (assuming the antennas are connected to it)
Thanks for any and all help!
