iphone 8 poor/sensitive mic during call

Just got a new iPhone 8 (updated to ios 11.0.2) upgraded from iPhone 6. When making a call if not talking directly into the mic the person on the other end cannot hear me (or my voice volume is drastically lower). This occurs when even slightly moving the phone away from my mouth or rotating the phone slightly up or down. My father has the same problem with his iPhone 8, even returned it and got a new one, same problem. Switching to speaker phone solves the problem. Also noting it does not happen all the time and a hard reset can fix it for a bit but then it goes back to the bad behavior.


Has anyone else experienced this?

iPhone 8, iOS 11.0.2

I found this interesting post on a similar mic issue thread for the iPhone X (thanks to brentwoodkennyg):


I sound muffled or underwater, but only sometimes. Other calls are perfect. Tried all of the fixes in this forum - Network reset, LTE off/on, full reset, wi-fi calls off. Noise cancellation off. With and without cover. Got a replacement phone from the Apple store. None of it helped and now I know why...


The issue turned out to be how I was holding the phone. There are three microphones on the X and one of them is located by the camera on the back of the phone. Even though I didn't cover it while holding the X (with fingers and thumb on the sides of the phone, I apparently was close enough to make that mic behave differently. When I move my phone-holding position in the same grip to the bottom part of the phone, the problems vanish. I have run through a series of test with my "complainers" and this seems to pinpoint the root cause. It's either user error or a design flaw, but there is a simple workaround. Hold the phone at the bottom of the case and definitely not near the top. Problem Solved!


Update as to why this works: Apple has designed noise cancellation into the talking side of the phone. (This is different than the noise cancellation in the Accessibility settings - those are for the listening not speaking). Anyway, there is a small mic on the back of the X by the camera. It's purpose is to listen for ambient noise (think crowded bar) and to cancel that noise from what it hears from the mics on the front at bottom of the phone. Those mics hear your voice talking plus they hear the ambient noise (crowded bar). The software "subtracts" the bar sound from what it hears on the front and the listener never hears the bar noise - just your voice. (You can test this by completely covering the back mic hole with your finger - then the listener hears the bar noise and has trouble hearing your voice).


Anyway, this is a really great feature - except that if you hold the phone near the top, it channels part of your voice into that back mic and it ends up canceling out all or part of your voice. So I have to hold my phone at the bottom and things work fine. This also explains problems with folding phone cases and issues when you are holding the phone between neck and shoulder.

I had an appointment with the Apple tech (Genius) for this coming Sunday as I had the same woes as everyone else with the 8 Plus i.e. People saying I sounded Muffled and no High or Low frequencies in my speech and really difficult to hear me.


I checked for any OS updates last night and there was one. I updated it last night and today I made four calls and everyone said it sounded fine ? Now I am not sure if they did a fix and didn't list it in the change log, but it seems to have fixed my phone.


I will test again fully tomorrow and make as many calls as I can and ask the person (Customers) on the receiving end how I sound before I cancel my Apple Shop appointment.


Anyone else done the update ? V11.2.6.

I have this problem with my iPhone 8 and have switched the phone out TWICE already within the first weeks of owning the phone because every single person i talk to whether US or International, speakerphone, headphone, direct or FaceTime cannot hear me after 30 seconds or so. I keep having to "re-load" by pointing the phone flat, then back up like a Wi Controller. I took it back a THIRD time (still within the first month of paying $1,000 for the phone) and Apple then told me it must be a software/carrier issue and to get a new SIM card. I did that this weekend. It doesn't work. I dont know what to do and Apple won't give me my money back.

I took my iPhone 8 into an Apple store and when I pointed out that my cheap three year old windows phone provided by my company offers better call clarity the “genius” told me “you can’t expect all phones to work the same?” . No but I did expect an £800 iPhone to work better than a £100 windows phone.


Pretty much every call I make I get people tell me they can’t hear me properly. I’ve had every iPhone since the 3GS and this is the first one I’m really unhappy with.

Re iPhone 8+ mic problems.

I asked Apple chat to help me find the USER manual, not the safety, warranty, regulatory manual which to me is worthless for my purposes although easy to find on Apple. However the USER manual is much more difficult to find, took the apple chat person 5 min to find it, then she sent a link, which I tried to paste here but the second I pasted it, it disappeared immediately. I tried to help y'all out but apple would not let me. Anyway the USER manual she finally retrieved was an older version that did not list the 8+ iPhone I bought - chat person said Apple had not updated the manual... go figure and typical! I only wanted to know the location of the microphone, turns out there appears to be 3 microphones. One one the bottom of the iPhone appears to be embedded with the left speaker on the left most side of the left speaker. Then there is another, embedded with the "receiver/speaker/microphone" in the top front of the phone, the oblong slot. Then there is another on the back of the phone between the rear camera and the rear camera flash device. So I didn't know until I saw this manual that there are three microphones. So, my mic system records voice notes correctly but is definitely week and pretty much unintelligible intermittently during calls. I believe this is most likely a software problem, most likely with the phone first, then the settings of the phone, and also could be a carrier, week signal problem. My problems come mostly when I'm at home. Called my carrier, I was advised to deselect LTE, power down the phone, then after a 10 sec delay restart the phone and reselect LTE. I was told to enable wifi calling which I did. Then I was told to reestablish a link to my home base cell tower by calling #832 which I did. So far, I'm not experiencing problems with the mic. This in my mind in no way lets Apple off the hook, in my mind and as someone else here said, the first thing these $900 phones should do impeccably is connect to carrier, talk and listen. This should be perfect and guaranteed. And if there is a problem the phone should tell the user what is the problem, and apple support people, which from a technical and capability standpoint have really gone down hill, should quickly and with first time accuracy be able to trouble-shoot the phone and stop apologizing for their and Apple's ineptness. Again, no more Apple stuff for me period. When it's time for a new phone the value to me is in a throw away phone. Apple has lost it's value to me. And if u have a new one that's still returnable, my opinion would be to return it and buy the cheapest possible unit that gives u the features u need.

Thays bot good at all ! My Brand New Iphone 8 Plus is doing the same thing and has been for 4 months! Had it replaced multiple multiple times. Have tried every trick in the book and zero fixes. Apple ia ignoring this Huge Issue! There are no fixes period! Call you carrier and complain! We sure did and got some results finally! Results are we are fully Leaving Apple for good! The New Samsung S9 and Samsung Watch has been Ordered!!!! So, So excited! So, So Very Disappointed in Apple and them not giving a stinking Crap about this issue! Sure hope they fix it because it was a pain in my back side to get into a different phone but we did !!!!

So True, So True!!! Apple will not be fixing this issue. I just dont think they have enough people complaining or setting up a lawsuit....I too had a 4 month old Iphone 8 Plus that I had replaced 3 times. Still , every replacement phone had the same mic issues and massive delays. I also kept getting kicked out to the home screen from apps. Restarted my phone all the time, removed and re-installed apps, and zero fixes. Apple has to be the one to fix this. So , I basically jumped ship and went to Samsung. There is a way you can get out of your Iphone 8 if you are under contract with your carrier. Go with Samsung. All Apple is worried about is designing and marketing an ALL RED Iphone 8. Who the flip cares!!! If we, Apple's faithful customers, cannot use our $1,000 phones with the basic, basic , phone function, why would we want a Red one...Apple needs to get their priorities straight!! Who really cares that an animal emoji moves! So many of us are having issues with Brand New Phones, I dont get it and its been months since they came out. What my understanding is, is, these new phones have 3 different Mic's which is the problem. The noise cancellation mic, gets used and its turning off the mic you need when making a call. So its turning off the wrong mic or turning off 2 out of the 3 mics. I always had people telling me, I can barely hear you......this is why, the mic isnt working right. Trust me, i've gone into settings and turned the option off and still no fix. So Apple has some big time issues happening right now. Quick making new fancy colored phones, (RED) and fix the ones we have already Bought and are trying to use for Work!! Even their Mac Books have a screen recall on them..... The company is going south everyone!!!! Thats why I totally switched to Samsung, I'm Totally Done with Apple Phones!!!

Hi,

I had the same problem and sendt my Iphone 8 to service, but the problem was still there. The I found out that the iPhone has I mic between the camera and the flash, If that is covered up when you speaks the the sound is terrible.

That is a problem if you have a wallet cover on your phone that you turn the front to the back of your phone when you speak

So do not cover up the mic on the back side of you phone during the conversation.

I have been experiencing a similar issue with my iPhone 7. I just tried turning off the noise cancellation and made a test call to a friend; he indicated it’s much better now. I have a lower voice which may very well be detected as background noise. To turn off noise cancellation go to Settings > General > Accessibility > Phone Noise Cancellation > toggle off. Hope this helps.

After two months of ”repair”-cycle, I finally got to return my X.

Apparently there was nothing wrong with the hardware because they couldn’t find anything wrong with the phone. Once I took the phone and set my appleid (from year 2008) the mic stopped working. So the PROMBLEM IS IN THE DATA, apple offered me that they would check my data too, but after two months I was ready to give up.

Now I’m trying to gather up enough patience to try out If the Xr accepts my old data. No problems with the same apple id using 4s or 6... so far my data has only f..ked up the X.
