Chosen Solution
I recently replaced my charging port because my old one stopped working about three weeks ago. I noticed about a week ago that the service on my phone was getting super poor. Now my headphone jack and speakers won’t work no matter what (I’ve tried everything). Now, considering that all three of these problems are on the same part, could it just be the part? Poor connections?
Faulty part, I assume the charging port connector on the logic board is fully plugged in with the lightning connector ribbon flex assembly. The charger port probably has JBL labelled on it. I’ve had my fair share of issues with some of them. You will just need to get another replacement charging port assembly and pray that it works. Some JBL’s work some don’t. It’s possible to obtain apple OEM ones (Which will work 99% of the time) but I don’t know where for now.
