What if the video recorded by Apple's mobile phone has crickets?

Apple's mobile phone uses crickets to record videos, and I can't help it. This is the sound of electricity. You can ask in the shop and see if you can fix it. Under the detailed information management page of the auxiliary function, select the switch button on the right side of telephone denoising to turn on the function. (When the noise reduction function is turned on, the phone will automatically reduce the noise when talking or recording video).
