iPhone X, phone calls and Apple's Folio Case

The rear mic is used for noise reduction. If it is covered it will cause the symptoms you are describing, as has been reported by users of other models that have the noise reduction feature. It really isn't a software issue, as there is no software fix for covering a microphone. It doesn't happen with dictation or voice memo apps because they don't use noise reduction. If you turn off noise reduction in Settings/General/Accessibility the problem should go away. Or get a different case.

It took me a while to figure out the mic issue. I’ve found it works best to fold the case/flap flush against the back, but on an angle clear of the cameras and mic. When it’s pressed up against your ear it feels normal. I’m used to it now and it works fine, but still a bummer on otherwise a good case and phone.

Hello all, 11.2 iOS update seems to have fixed the problem. No more muffled calls. A simple fix to an annoying problem. I’m glad because the folio is the best case I’ve had over the many years of iPhones.

The thing is other folio case doesn’t need to be folded back to take a call take the tech21 Evo wallet for example it has a speaker cut out on top all you need to do is open up the front cover accept call and close the front cover, there’s absolutely no need to flip the cover to the back. Apple folio case however has no cutdown for the front speaker you got no choice but to flip it to the back and take the call, in saying that I think most aftermarket folio style case has cut out for front speaker so there’s no issue using other folio case at all

I had the same problem. The open flip cover overlaps the microphone between the rear camera lense (little hole), which is responsible for the background noise cancellation. Phone calls are not possible like this, except you hold the case open like a book, which is not practical at all.

I went several time to the telekom shop where I bought the phone and to an apple store. They did not know anything, could not help me and suggested to "repair" the phone (which would take 2-3 weeks)...

Best solution: Send it back to Apple. I bought the Otterbox Strada. Leather is not a fine as the Apple folio, but everything is working...

There is nothing wrong with The folio case from Apple. All folio cases have this problem in combination with the iPhone X. It is because, when you fold the flap completely behind the phone, it covers the little microphone between th two camera lenses which is used for noise cancellation. I guess the algorithm used for noise ca gets confused with the case rubbing against

A work a the microphone.

Bump for visibility. I’ve been struggling with this issue for 2 weeks, thinking it was somehow related to my phone service provider that I’d swapped to at about the same time. It was starting to affect my work significantly.

Fortunately I stumbled on this and another related post on this forum (thanks guys). Swapping to a regular leather case has solved the problem for me.

The exchange was hassle free, although the 2 store employees I spoke to had not heard of this issue at all.

Bonjour, je confirme,j’ai,moi,fait plusieurs essai avec plusieurs etui folio de marque differentes et toujours le même Problème,mes interlocuteurs ce plaignent de mal m’entendre quand je replie l’etuis Pour répondre au téléphone .

Il existe une solution il faut trouver un étui folios qui permet de répondre sans rabattre à l’arriere Le volet du folio il en existe plusieurs qui on des trous en façade et un trous en bas pour parler il faut aussi paramétrer le décrochage automatique et le Tour est joué.

Cordialemen’y

It helps when you don’t fold the case completely shut but leave some space. As a work around I leave one finger between the back of the phone and the “flap”.

Confirmed with iPhone X and Apple folio case. Folding back flap during calls leads to significantly reduced audibility. Not folding back flap during calls leads to normal audibility. It is likely related to the microphone on the rear camera assembly.

iOS knows when an Apple Folio case is on, as the Settings feature for “Lock/Unlock when opening cover“ appears when the Apple folio case is installed. They should be able to change the microphone characteristics when the Apple folio case is on. I’ve filed a bug report under hardware/iPhone and recommend others do the same.

11.1.2 does not solve the problem - it is not a software/firmware issue. It is due to the leather flap itself. Strange that Apple didn't see this simple design flaw in their folio case. Actually amazing.

It has been reported with the iPhone 7 and later, with this type of case. It's not restricted to iPhone X. And it should be obvious that if you cover a microphone that it will result in muffled sound. It's physics, not something that can be easily fixed in hardware or software.

I help a lot of people taking pictures through a submarine periscope with iPhones, and these cases also interfere with use of the camera. It's just a poor choice of case for any smartphone.

Bonjour, j’ai résolu le problème, Apple store France m’a rembourser le produit(même après 30 jours .

j’ai trouver un nouvelle étui de la marque TORRO uk Qui ne pose pas de problème , l’aiman est placé à un autre endroit.

la solution peut aussi venir avec un étui folio sans aimant , à ce jour Apple n’a aucune solution pour ce problème.

Yes. It is due to the noise cancelling microphone element on the rear of the phone, located with the camera. If it’s covered, the system can not work properly, hence the muffled sound. VERY poor design, and even worse per release product testing.

Thanks, Roy
