I recently replaced the rear housing of my iphone 8 plus and I now have really bad reception compared to other iphone 8 pluses on the same carrier. I broke the top antenna flex cable but have now replaced that but still have bad reception. Is the antenna itself located in the rear housing and would that be why I don’t have as good reception? - (when i say reception i only mean cellular reception, wifi has been absolutely fine)
I had a look and one of the bracket connectors had snapped, so I replaced that and it’s working beautifully
Is the housing original or aftermarket? Some aftermarket housings may not have proper connections to use the housing as an antenna. I’ve read in some posts that adding a bit of solder on the connection points on the housing may solve the problem. Correct me if I’m wrong.
