My techs and I would see this a lot after sloppy repairs from other stores. Usually we would open the device back up, and make sure that the radio wires are connected. 90% of the time that was the issue. Also when putting in the cover that goes over the charging port, we would see that sometimes the radio connections would become loose. Especially for the one right in the middle of the charging port board.
