iPhone 11 Static Noise in earspeaker

Sorry for my bad English

I have problem with static noise in my iPhone 11earspeaker. The static noise occurs only during phone calls. When I'm listening the music or watch the video there is no noise. Or even I'm doing phone calls in my Airpods in this case there is no issue. Static noise on my iPhone started from the box. I reset my phone and start like brand new, did all recommendation given Apple technical support. Everything useless. Apple service can't diagnostic the static noise by ordinary tests. Also the IOS updates nothing solve.

From my point of view apple know about this problem. In apple community discussed crackling/buzzing/rattling noise in earspacker starts from IPhone X. Many users waiting for a solution from apple for long time and desponded due to no solutions.

I think the problem is caused by software. If the problem was coursed by the hardware, the static noise I here every time no matter what you do (watch the video, listening the music and so force).
