Why does my iPhone X makes thumping sounds inside when I turn sound on and off
Why does my iPhone X makes thumping sounds inside when I turn sound on and off? It's a replacement I received today, and I noticed this right away. It took hours to finally get everything moved over from my original phone, but I'm afraid to keep it. Any ideas on why it would do this and a fix?
iPhone X, iOS 11.4.1, new replacement
