I have replaced the charging port on my iPhone 6 three times with new units. Each time the phone has little or no reception and cannot place or receive calls. I put the original port back in and each time everything works again. I even requested a port from one place that was compatible with Verizon CDMA and had the same results. I don’t know how much longer I can get my phone to charge before the port craps out completely. Does anyone know why none of the replacement ports will work?
1.) Why are you changing a working charge port? 2.) Are you fully installing these ports or just overlaying them to test?
there is another part in the phone that is used for a cellular antenna, that could need to be replaced, that and i would also try DFU restore/update
