Weird sound when recording video on Iphone XS
Hello. When I record a video, sometimes I get a very short strange sound, like a muffled knock, while I hold the phone straight, do not pull, do not knock on it. The phone seems to be in good condition, the sound appears quite regularly when recording a video, but not when recording a voice recorder. I tried to shake the phone very hard while recording and quickly zoom in on the image, but I can’t specifically reproduce the sound. The problem can be heard on the recorded youtube video after 0:07 seconds, but this is not related to the camera zoom x2. What it is? Has anyone experienced this? Is it scary, and is it possible to get rid of it?
iPhone XS, iOS 16
