iphone 8 poor/sensitive mic during call

I installed 11.1.2 as soon as it was available for my freshly bought iPhone 8 256GB.

It was working just fine until the day before yesterday.

Without any reason the people on the other side are not able to hear what I'm saying during a phone call. In car bluetooth system as well as headphones work ok.

I was going to send my phone for the repair but now, when there's so many similar problem description on the web I am not sure what to do. The phone is basically useless for me right now.

Mostly all 3rd party apps use either the rear mic or only one bottom mic, therefore an actual “in call” test will be the best because the os and hardware utilizes both mics depending what side of the bottom your closer to. It’s been a full week on my 5th 8 and no issue. Yet. ...

I had the iPhone 7 plus with the same problem. Restored it couple times and it worked fine. Then 8 plus and the same problem. Restore couldnt fix it so got it replaced and now it works fine. So glad my X doesnt have any of these issues

My husband finally decided to get an iPhone, so we got him the 8 and now he's having the SAME ISSUE. This is not a good thing for someone who finally converted to Apple (after years of coaxing). Please please please fix this issue. I can't hear him at all half of the time when I am on the phone with him, and the phone is most definitely close to his ear.

Just an update. Say a post about blowing air to remove any dirt in the bottom mic’s. Just blew on them (no big canned air required) and seems to have sorted out the problem. How dirt could be built up in there when less than 3 days out of the box but it works now.

Hi - I have an iPhone X and had the same issue, I have just spent all morning on the phone to Apple and in the end it turned out to be my very expensive Snakehive case for my phone. Try taking the phone out of the case and try phoning someone, I couldn’t believe it. Basically there are three mic’s and two of them were being blocked by my case 🙄

I don't think that's it. My wife was essentially forced to buy an official Apple case (iPhone 8+) and the problems continue.

The real clue to me is that it happens most often when the phone is used a quiet environment. In a noisy environment, it actually sounds better. My theory is that the background noise cancellation is overly aggressive and cancels the user's voice out sometimes when used in a quiet environment. When given a steady bit of background noise to deal with, it works fine. It's either that or a very common hardware defect.

I had this problem, took the phone back and got another with the exact same problem. My boyfriend, who is an android user thinks it is hilarious that my wonderful, superior, new iPhone is having problems. I hate to admit it, but I am about ready to switch to a Samsung myself. Please help!

I spoke to soon when I said the micr. problem was solved by Apple.

The sent me a new Iphone 8, in first everything seemed to be OK with the microphone but after a few days people starting to tell me the the volume of my voice was very low again and fading in and out.

So I don't know what to do now, maybe contact with Apple again, think I want my € 950,- back.

Making a phone call should be the first thing a phone should do perfect!

Gr.,

i'm having the same issue on my brand new (2 week old) iphone 8 plus 256gig....i'm very disappointed by that. i have tried everything. and experience the same issue..only with normal voice call. any vociecall via app over the intnert such as whatsapp call, facebook call seems to be working perfect.

It would be courteous of Apple to acknowledge there may be a problem on (some) iPhone 8s and perhaps even indicate they are investigating.

It seems this may be a problem of some kind with the cell phone noise cancellation or microphone encoding level.

Apple?

Okay I had the same problem and I went to the Apple genius bar tonight. What the genius spotted was the wallet case that I am using folds back onto the back microphone when you’re talking on the phone this microphone apparently used for noise reduction and causes it to go immediately muffled sound when you talk on the phone.... Without the case closed over itself at the back it works perfectly. So in might account for some of your problems because mine was exactly the same worked on loudspeaker worked on the headset but was muffled on the microphone...therefore causing this problem. But I think it’s intermittent because the way I hold the phone it’s not always the same and sometimes the back microphone the one near the camera would be exposed and sometimes it would be closed over with the back cover. I took the cover off and guess what it works perfectly. Every time I gave it to Apple to check I took the phone out of the case and gave them the raw phone so it took awhile for them to work out that I actually had a case. Hope this helps everyone.

i have found a solution.

the back microphone near the rear camera lense is being blocked more than likely by your phone case if you have a folding phone case, if you remove it or prevent it from blocking it then it will be working fine.

I tried it and it's extremely fine. this guy initially posted his finding and it turned out to be the case for me.

let me know if this works.

The problem still persists when using the "official" slim apple case (i.e. not folding). I don't think it's necessarily a case issue. Also note, it seems to happen more in quiet environments. So if you're in the mall / Apple store, it's probably going to be harder to replicate the problem.

Hi Keith I have the same issue with my Iphone 8Plus, purchased on 2nd November 2017. No one can hear me unless i have the headphone connected or connected to bluetooth. Speaker phone also works, but regular mic does not work everyone tells me they cannot hear me.. this is extremely embarrassing as I am calling clients and they almost hang up me as they cannot hear me. I have to shout very loadly for them to hear me and in an office environment this is very ofoff putting to my colleagues and down right embarrassing to me. Apple just told me to try and record on voice memo.. well this works fine, but still people I call cannot hear me.. Next idea was to download IOS 11.2, well did that this morning and still no good. I assume now they will tell me to reset the phone another waste of 45min of my time.. I can see that you have had a huge response to your post.. did you manage to get the issue resolved or do you still experience the mic issue?

Thanks

Paul
