Replaced iPhone 6 Lightning Connector, now cellular reception is poor
I replaced my iPhone 6 Lightning Connector with a new ifixit version because it was not charging very well. Anyway, the phone is all back together and my cellular service is extremely poor now. Any ideas what the problem may be? I've taken apart several iPhones and I'm pretty sure I got everything back together correctly (including the antenna connector), but I certainly could have missed something. Is it possible the ifixit replacement part is perhaps a lesser component? Was there some critical step in the process that could make or break the cell reception?
