My iPhone 11 microphone is extremely weak all of a sudden, not actually sure if the main microphone is even functioning, or the sound that it picks up is from the secondary mic. I’m looking for a way to test the mic and maybe fix the issue
Use dry interdental brushes (0.3-0.5mm) and poke them around your microphone port, do this as much as needed hopefully your microphone will work like new. Most importantly make sure these brushes are dry when you insert them. They should bring out any moisture or particles which might be jammed inside the port. I hope this helps
