Iphone Mic Noise
My iphone’s microphone is making a huge noise whenever I use it!! It is not a crackling noise it is a straight up ringing sound as if there was an interference
iPhone XS Max, iOS 13
See this support guide:--> If the microphones on your iPhone aren't working - Apple Support
If you get no improvements, make an appointment and have your iPhone inspected at an Apple Store or Authorized Service Provider:--> Apple – Location Selector
