iPhone 7 Microphone Cutting Out

I have a new iPhone 7 Plus 128gb running iOS 10.0.2. During phone calls, both speakerphone and handheld, callers tell me that while I'm talking, my voice will cut out and they hear garbled static (btw, this happened before updating to 10.0.2 as well). It is like wind noise in sound. Sometimes it works without issue, and other times it doesn't. After a call is ended, I can call back and the caller says that they can barely hear me, but the static is not there anymore.


I am in the process of restoring the phone to factory settings to see if that will fix the problem. But it really sounds like a hardware problem. Does anyone know of this problem being similar to yours Or one that you've heard of?


would you think that this is a hardware problem rather than software problem?


If it is a hardware problem, should I work with AT&T where I got the phone or should I try I do a warranty replacement through Apple?

There is a microphone on the back of your phone, at the top right next to the flash. It's a tiny pinhole. Make sure that isn't covered by a screen protector. It has to be completely open. I had a glass protector partially covering mine. Removing it, solved my problem.

Okay, in that case I would suggest you wait until next week after iOS 11 is officially released and then call AppleCare and ask to speak to a senior specialist. Just be aware they are really busy following the release of a major update and since 32 bit apps will not work in iOS 11 it may be a bit busier than usual. And try to be a reasonably decent human being and not a toxic person. If you can.

Hi ttttttaaas, please relax a bit. Hope that after a good night sleep you feel better.


Wait till monday, do this full restore thing as AppleCare suggested - I plan to do so - and if it's then still not correct or fixed, I suggest to go full force on this as I know you want to. When not fixed I will be in touch with my appointed AppleCare guy asap.


@deggie, please keep it polite and respectful here and don't trigger people's frustrations unnecessarily. We are all Apple enthusiasts here, but there is really something faulty with the iPhone 7 and 7 plus devices for quite some users, and for quite some time now. It's absolutely frustrating when a 2016-launched premium phone is not doing it's basic functionality 100% correct when there are much simpler phones and like 4-5 years old or more, out there that have zero issues with this basic functionality of having proper conversations during phone calls. AppleCare has confirmed to me many months ago - read my posts here if you like - there's something faulty. Only the fix takes a long time. And everybody deals differently with that. But please keep it polite and respectful. Thank you.

Hi ttttttaaas,


‘We’ are all quite disappointed. Because it’s ridiculous.


My road for having this fixed is lasting already for 10 months.


My senior AppleCare guy told me today that in 2 months we will be in touch for a year.


That’s ridiculous.


And before I was connected to him I visted the Apple Genius Bar in Amsterdam 2 times. But they can take the “Genius” out of that name. Just call it the device replacement or the hard format bar. That’s all the solutions they came up with and none was effective.


Also with my iPhone 7, my replaced iPhone 7 and the granted by Apple iPhone 7+ as a thank you for all the effort to get it solved ... everytime all the tests work fine. That’s what’s frustrating about this. The phone not in use by a user, functions perfectly according all tests. But it’s the phone while being used, where it’s malfunctioning. And Apple then blames the user ... and is apparently unable to approach it from the angle of a faulty design of (some of) the internals of the iPhone.


We all know that by now.


My senior AppleCare guy confirms that there are many more who have this problem.


Today he asked me to try the noise cancellation thing in iOS11, but he confirmed afterwards it did not solve the problem either.


The problem with phone replacements is that they can be perfectly similar faulty phones, just refurbished ‘Apple style’. Phones that have been turned in - and after similar diagnostics like you had today - it appears to Apple that the device is perfectly fine, and then the ‘faulty’ configuration that seems to be fine will be just as well re-used. Because there’s no reason not to. From that perspective understandable, but as such we end up by a faulty iPhone 7’s circulation, or iPhone 7 plus’s for that matter that has the same problem.


One more month and then I consider to exchange my iPhone 7 plus 256 GB for the iPhone X 256 GB. And fingers crossed that that X iPhone is ok for making amazing clear steady phone calls. Hallelujah!


By the way, my friend has Samsung S8+. He has received already his 3rd new one, from Samsung as it appeared not to be that perfectly water tight (so he said). Though I must agree that’s not as bad as not able to make steady phone calls ... as you just should keep yourself from swimming with your phone. Fair enough.


My ‘problem’ is that Apple has currently a ‘vendor lock-in’ at my place as all is Apple at my place as it does all beautifully interact. Otherwise I could have maybe changed to another phone brand by now.

Sep 28, 2017 3:32 AM in response to ttttttaaas

Like many here, I’ve gone through 3 iPhone 7’s, and tried absolutely everything to no avail. It can really only be a hardware issue, whether apple will recognize it or not.


I finally gave up, and paid for a 6s out of my own pocket, which I’ve been using for over half a year and it has functioned perfectly all along.


I’d be interested to learn whether the outgoing sound issue has finally been fixed in the iPhone 8 and/or X. Anyone?

Oct 3, 2017 1:23 PM in response to htirevold

The bottom line for me is that the issue does not exist as far as getting help from apple. I've been to the store, I've been on the phone several times. This is something we will have to deal with on our own. It is not a widespread problem enough so for apple to fix it or work on a fix for it.

So, for all of us here having the issue, use speakerphone, headphones or bluetooth. As far as apple is concerned.

I've had tmobile make an exception for me and I'm being issued a Note 8.

Not sure exchanging the phone will make any difference iv had 2 swops still they same think

They are hoping the problem is solved on 8

And everyone will pay a high price to up grade

Its so frustrating when your talking to someone and they keep say cant her what your saying your muffled u see so many poeple talking into the end of phone with speaker on i will not be upgrading unless they sort the problem out i brought out right for £650 8 months ago not just us on are her iv asked lots of poeple with 7 if they have the same problem they say poeple do complain they cant hear apple please sort it out

Oct 17, 2017 4:20 AM in response to bartgrp

Thank you bartgrp for sharing those details. Great post.


I am now with my senior apple care guy working on this for over 10 months. I left a lot of posts here regarding developments and progress. And recently had to undergo some new testing and making calling log-files and sending them to apple engineering and all. It seems to be a very persistent and nasty technical problem. No clue why it takes so long to fix it, and having more and more people annoyed over their user experience with iPhone 7 and now iPhone 8 too as I understand from your post, even worse with iPhone 8.


Every important message posted here with new angles or info, that I get an update from via email, I forward to my senior apple care guy. I recommend others to do the same when they are in direct contact via email with an apple care guy or lady. Keep everybody informed about our findings. Just forward it to your apple care contact and type FYI on top. Hardly an effort, but good to know that the apple care guys and ladies are constantly reminded and informed.


Your information about iPhone 8 is very valuable at this point, because I was already informed that no guarantees were or could be given regarding this problem for iPhone 8 ... but I did not saw it confirmed or discussed anywhere, till now via your post. Thank you for that. And thank you for your effort of visualizing the problem as well with the image.


The problem can also be explained as when you are calling and you would be tapped on your other shoulder, that you will turn your head in that direction while holding the top part of the phone to your head/ear. It's just such a little movement that already causes the phone/mic totally drop. Every time. And that is quite a normal situation, a head move like that while talking and looking around (for example during walking or looking through documents while talking with someone).


I am keeping my fingers crossed for iPhone X that I am interested in (also because I curently have an Apple vendor-lock at my house and office, it's all Apple stuff), but I better wait for people to confirm it is not having this same issue.


Thanks again bartgrp for your great post. I already forwarded it to my senior apple care guy, who is really working hard to get it solved for me and users in general. But it's a persistant and nasty technical problem ... it seems to be.

Don't blame your carrier. I'm with Verizon and have the microphone issues too. It's not the carrier, it's Apple's problem. Beyond 3 months, why should the carrier cover this problem. Apple made these defective phones, not the carriers. The carriers just provide the service to allow these phones to work. However, I do think that the big carriers should force Apple to buy back these defective phones or replace them with new phones rather than refurbished phones (that obviously have the same problem), or a different generation phone altogether. APPLE ARE YOU LISTENING?

Oct 29, 2017 11:04 AM in response to Inquirer for info

Obviously, because I'm here, I've experienced the same issue. It became apparent soon after I bought the device. Instead of letting my carrier (Verizon) send me a refurbished phone, I went straight to Apple and had them send me a new one since it was within the 1 year warranty period. The new one functioned well for a few days before starting again to cut out when using the phone feature. After several more months, I actually took it to the Apple store in Spokane, WA where they AGAIN replaced my phone. On the 3rd brand new phone and having the exact same issue. I've tried all the standard fixes mentioned here. All the restore options, turning off the HD calling (LTE), restoring network settings, yada.. Today, my girlfriend called from the road and said it was so bad she just said lets talk later. I'm inclined to go to Verizon and just buy a new phone. However, I'm hearing rumors that the new iPhone 8s are doing the same thing. Have even thought of going backwards to a 6. I really wish they would figure this out.


Iphone 7 plus, 128gb, in black. 3rd phone, same issue going on 9 months now.

Nov 14, 2017 3:07 AM in response to bartgrp

Just to add to my original post. We have acquired an iPhone X and the problem is the same! Again, if we cover the mic as described above the problem is resolved. I'm sure Apple will be aware of this, so either don't see this as a problem, or have chosen to ignore it.


Part of me thinks Steve would not have allowed this to happen!

Nov 17, 2017 2:04 AM in response to Inquirer for info

my phone is 7 months old already changed but they just you a recycled unit with the same problem,

to prove that its the phone i just purchased a £199 huawei p10 lite changed my sim over to try after a week i checked with all callers if i sound distorted and deliberately moved the phone away everyone has said i sound was very clear and infant they sound clearer the speaker also, of coarse the p10 is android so keeping the i7 will probably get a cheap sim in it and use it as stand by until apple sort out the problem,by then may find other phone is better alround

Dec 29, 2017 5:21 AM in response to mr.aam

I had the same problem since few months now, changed the service provider still the microphone problem continued, contacted apple service center in UAE, got the 7+ 128gb replaced with a brand new 7+128gb, updated the software to latest iOS 11.2.1 the problem still continues:(. Now booked an appointment with service center again... don’t know what they would do to resolve this issue....

Feb 23, 2018 5:23 PM in response to belinda61463

Ok, so 3x iPhone 7 plus and 1x iPhone 8 plus, all same problem with horrible call quality, doing all the recommended steps. Clearly, Apple is clearly a LOW QUALITY product now.... Support does not care. I thank God, my provider, AT&T took care of me and credited back for the phone and I am using my OLD iPhone 6 Plus that still has excellent call quality! Good Luck and my next phone WILL NOT BE AN APPLE! Run, don't walk...
