Iphone 11 crackling noise/ static fix

If anybody is having problem with their new iPhone 11/11pro/pro max voice call/video call static sound please try removing the phone case and try again. If the voice call video call static sound problem still persists without the protective case that means you have issue with your hardware. If the problem goes away when you take the phone case off, that means the phone case is designed badly and does not work well with iPhone 11 speakers and microphones. I removed the phone case and the problem was solved in my case.
