iPhone 7 Plus Phone Call Sound Quality

I have the same issue too! I ran across your post when i went on goggle to see if others were having the same issue. I just got my iPhone 7 plus a week ago, and this is drivIng me crazy! It sounds as if the phone is hollow inside and the first time it happened I actually pulled away from the phone thinking I mistakenly pressed speaker phone by mistake. It's so bad that I can't have a private phone call as anyone standing by me can hear what the person on the other end of the call is saying. Even speaker sound quality sounds weird, and there is this annoying way the phone reverberates when the sounds are coming from the person speaking at the other end.

I have the same issue with my iPhone 7 plus Matte Black 128 GB. I'm at my 2nd replacement phone for the same call sound issue when calling from the phone, not any other app using the mic is making this issue.

I tried something though and it seems to work for me, maybe it's going to work for some other people too. While the noise cancellation is activate (or not, it doesn't matter because for some reason the back mic seems to be always working...), simply put your finger on the back microphone between the camera and the flash and talk. It should be okay.

The back mic seems to receive the voice whether the noise cancellation is on or off and that must be why our voice is getting cut while talking on the phone but not anywhere else. I guess it must be some kind of calibrating issue (probably within the Phone app) itself, considering it's not making it with other app.

I'm running the latest Beta software and the issue is still there, I sincerely hope Apple is aware of this issue (and it doesn't seem to be physical considering no other app is having this issue.

Tell me if it works for you too, I'm curious!

We'll at least have some sort of workaround until it's permanently fix!

I took this issue high up in Apple Ireland which involved Apple Engineering, I had to install a diagnostic App on my phone whilst they took various logs over a couple of days of using my 7+. Once dignostics was complete my phone call quality improved though still not as expected of a high end phone. Who ever I've spoken to at Apple have made the point that this issue has been reported by a minute percent of Iphone 7 and 7+ owners, this made me realise they don't care. For me the best option is move to the new S company S8 due out soon, if the A company don't care and insist there isn't an issue why stay with them. It's quite clear the A company are reading this tread, I've sent them links to this and the Facebook thread but they still deny there's a problem so why not take our business elsewhere. Whilst the S company had the well publicised battery problem they owned up and rectified the situation, I experienced this as a Note 7 owner that wishes he didn't move to the A company.

I was experiencing the same issue with my iPhone 7, people I was talking to weren´t able to understand me, mic was cutting out, I sounded muffled etc.. Took my phone to the Apple Store and they gave me a new one, which is now working as intended. So I´d advise you to visit an apple store, and insist on getting a replacement. Good luck, greets

Same here in the Netherlands. Day before yesterday I got my third iPhone 7, but people I call keep complaining about fading call volume and/or garbled or muffled sound.

Fed up with talking to Apple and Vodafone support staff, I finally decided to hand in the towel and got myself an iPhone 6S, which turns out to have none of the problems the iPhone 7 seems to suffer from. I guess I'll just keep the 7 as a spare...

i am also , i just buy 7+ , rose color 128G, during talking phone with my friend i can hear my friend speaking clearly , but my friend can not hear my sound clearly , they said my sound very low and some time cannot listen , looking signal transfer problem , but every friend said the same , i hope it because software problem not because because Mix or some hardware in the phone, and hope apple will be reply to this problem .

The same thing in Croatia. Network T-mobile.

The problem is in Intel modem. Check yours models of iphone 7. Intel models are A1778 and A1784, the Qualcomm models are, A1660 and A1661.

I can't post copy-paste post here.

Sorry 4 bad english.

Dear friend the problem came when you use Mobile data 4g

put off 4g off all time even when you use WiFi after that you can see full signal

the problem not from audio system

there is conflict between the signal and mobile data 4g butter keep it on 3 g

What you see in this long thread is an example of the maxim: For every complex problem there's a simple solution - and it's wrong.

There have been several different solutions suggested, and each of them works for some users. And some users don't have any solution that works for them. It's a symptom with more than one cause.

I have the Qualcomm chip (and the one of those two that is considered better). It's still been happening to me. It's not every phone call but when it is it's very frustrating.

I hope this gets figured out soon, all my previous iPhones didn't have this issue so it has to be something that's different this time.

I have the same issue with poor quality microphones on the iphone 7+ since day one (and this is my first Apple phone product since moving over from Samsung). Callers complaining I sounded muffled. Followed all instructions on IOS upgrade, memo test et al. Have sent it back to be fixed, they did a hard reset and IOS upgrade (still confused about this as it was already current).

During my own testing which included turning noise cancelling off, I found the position of the bottom of the phone in relation to your mouth greatly affected the quality. When the phone is direct centre of my jaw line the call quality improves, move it an inch up or down and the quality degrades significantly.

Sorry I cant offer any more, but position seems to be everything!

I sent the phone back to Optus (I am in Australia), they hard reset it, updated the phone and returned it to my claiming it to be fixed........and it was the same. Went back to an Optus store and they replaced the sim card, and now work much better. Quality is still what I expect from a brand new phone, sounds like I am talking in a cave, but nothing more I can do about it now it seems.

Same problem here on the iPhone 7 plus. People can't hear me good when I talk to them. They say I sound muffled, go in & out, and can't understand me. I had just bought one & exchanged it once for this problem & the rep at the sprint store actually said we won't exchange it anymore, this is it!! This new one does it too!!!

Hi All, thanks for all the tips and my experience is much the same. I bought a new iPhone 7 three days ago and immediately noticed the poor audio from the called party. The received quality at my end was fair but not as good as the iPhone 5S which continues to be excellent both ways.

I found also that using the phone without any case improved the quality considerably and by covering the rear microphone made it worse. Turning OFF noise cancellation also improved the situation.

The choices seem to be either use it without the case and wait for an IOS fix or return the phone and chose something other that an iPhone.

Very unsatisfactory but very good for other competitors!

I have exactly the same problem with the iPhone 7 and the dutch network KPN.

People keep complaining that they don't hear me.

I can't keep replacing my iPhone 7 again and again and again. Its time that apple admits this problem like S did with the note 7. Im guessing its a hardware problem and not a software problem.
