Videos recorded on my iPhone 13 Pro have disturbing background noise

All videos I capture with my iPhone 13 Pro have weird noise in the background.

Sometimes, it reminds me of static or white noise; sometimes, it’s pretty loud and crackly and it sounds to me like some type of strong signal interference. The weird thing is that all those sounds and noises are never during the entire video; they randomly start and end at different times, so some parts of the video are fine. What I found strange is that calls or voice memos are clean and do not exhibit any sound distortion issues so I assume it's not an microphone issue.

Also I tried to test all of the tree cameras on the back and camera in front under different conditions to see if it's issue related to only one lens, but surprisingly, videos captured by all of the cameras are producing results with weird noise in the background, which makes me think if it could be some issue with the flat cables or connectors that are causing some interference?

I read through all the different suggestions online, like restarting the phone, switching off recording in stereo sound, etc., but none resolved my issue. I wonder if more people have this issue and if any other suggested solution exists.

I’m capable of replacing the microphone, camera, or other spare parts if there is no other solution, but before I experiment with that, I’d prefer to try some less risky pathway.

Thanks for any relevant comment.
