Bottom microphone stops working after first repair
I'm suffering from this problem for several months and still have not found a solution. After first time I tried to repair my phone (I wanted to replace a battery), something wrong happened to a bottom microphone. I replaced headphone jack/mic/lightning connector, but this still did not solve the problem. Some people say that something might happen to a part of the logic board which is responsible for the microphone.
Are there anyone who has/had the same problem and somehow found a solution? I'd be very grateful if you share your knowledge about it.
Is this a good question?
