Hello, i just changed the lightning connector on my Iphone, everything works great! except!!!! no once can hear me. Any suggestions on where I need to go and check? Thanks.
Did you change just the lightning connector? Or the whole charge port cable assembly? If the whole cable, more than likely there is an issue with the bottom microphone, which is part of this assembly on the vast majority of iPhones. At least as far back as the iPhone 5, but possible further back than that, This could be a simple as the microphone is not properly aligned, or the connection between the cable assembly and the logic board is not good. See if a simple disconnect and reconnect of the cable helps. But it’s more likely in my experience that the replacement charge port assembly has a bad microphone. Or that when it was installed, there was some minute damage to the cable, preventing the mic signal from getting to the logic board at all. Which iPhone is it specifically?
When you changed the part did you remove the plastic films protecting the microphones? Also make sure the microphone is sitting in position where it should be. If it’s slightly off it might be blocked by the adhesive.
