Hello, I have an iPhone 7 Plus that the microphone stopped working. I replaced the Lightning port with the microphone and it start working, but then Loudpeaker stopped working and when I put loudspeak or youtube video I can hear it only from the earpiece. Anyone knows why this could happen?
The loud speaker needs to line up with the gold contacts on the charge port flex. If they are misaligned, speaker won’t work. Also, there is a possibility that while other things function such as charging, the port could be defective. It’s common in small parts like these. It’s worth trying another one in case reseating the speaker as I mentioned about doesnt work.
