I recently got an X from US Cellular literally about a week ago. So it has the two year Apple care+ etc. and I love the phone so far! Though I noticed that when I’m on a call, or when I’m even FaceTiming, the phone speakers “pop/crackling” and sometimes it makes it every difficult to hear the other person. It’s happened 3 times (2 calls 1 FaceTime) so I know it’s not an isolated issue). I’m not running any beta software and it’s at the highest firmware 11.2.6. Any one have a similar issue? Should I call Apple? Or is there a fix/setting for this? Thanks everyone ahead of time. And I’m sorry if this was posted before.
