    I got an iPhone X through my carrier (Fido, Canada) Dec. 10 and immediately had problems with it as a phone: people complaining they can’t hear me clearly.

    I tested the mic and it works A-OK with all other apps (including Voice Memo, Facetime). I sound clear to others in Phone feature when switched to speakerphone – only muffled in Phone app, and only when I switch off speakerphone.

    I consulted Apple Support, diagnosed+reformatted the phone with an Apple Store Genius, deleting my backup and running only basic config and latest iOS 11.2.1, tried everything suggested by support, from checking mic for debris / case blockage, to resetting network settings, enabling/disabling LTE voice and background noise filter.

    Over 2 weeks + dozens of hours troubleshooting. I finally convinced my carrier to exchange the phone as defective, but I’m having the same problem with Phone X #2.

    Apple urgently needs to review the Phone feature app. It’s clearly a software problem + I see in forums online I’m not the only one, and it’s not restricted to the X – some users of the 8 are reporting the same issue.

    Have a new 8. Having call issues where people can’t hear me and occasionally I can’t hear them. Frequent enough that this isn’t normal.

    I know this sounds stupid but how are you holding it? Do you have any fingers near the camera area? I have found with all the newer iPhones if you have anything near that area it messes with the noise cancellation.

    Try it, call someone and talk to them like normal then put your hand near or over the camera area and ask them if it sounds like you are in a tunnel. It happens if you have one of those fold over cases every time because it messes with the mic.

    I know it is weird but it happens with people with hair over the area or if you are too close to something like the window in your car.

    The Apple iPhone X Leather Folio. Mic is open at bottom and mic works with all other apps with phone in case.

    There are issues with the folio case and the noise cancellation. Google it and you will find references to it.
