iPhone 7 Microphone Cutting Out

In my case the problem is ralated to gps, turned it off and all is good.

Turned off ”share my iphone position ” and turn position on again. Its working fine accept when i receice calls while using maps, but i can live with that.

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...

Further to my visit to apple service center 4 times no solution they could find to resolve the microphone inconsistency problem. As per their test parameters everything is working properly, but when I make calls after few minutes of communication voice goes down and some time almost nil voice for the receiving end. I was really surprised to see the way Apple store at Yas Mall Abu Dhabi dealt with me, they didn't even bother to study the issue even though I have spend hours and hours visiting service center and bring this issue up four times even after receiving a replacement unit. It seems Apple has achieved enough and more customers now and customers who brings up the complaints are only a nuisance for them not an opportunity to become better.

We have a fleet of around 40 iPhone 6’s and 7’s. We’ve had frequent call audio issues with the iPhone 7, where the recipient of a call from the iPhone hears broken audio.

Through testing, we have managed to replicate the issue. If the caller is talking, and moves the handset away from their face (as shown in the images below), the call recipient hears broken audio, every time! This does not happen at all with our iPhone 6 handsets.

We’ve tired adjusting the noise cancellation settings to no avail.

We have found a temporary fix. By covering the rear mic (in between the camera and flash) with tape the problem disappears, every time!

We’ve been to the Apple store and gotten nowhere with the “genius”.

We also have just bought an iPhone 8, and it’s even worse than the 7!

I have the exact same problem. Is your phone still working good after the restore to factory settings? I will look up how to do that and hopefully it helps. Very frustrating on a $900 phone

I think I will try your method first before I restore the phone. Thanks

I am glad I found this thread as I thought I was cursed or something and it was just me this was happening to. People constantly tell me they can't hear me and I hit the speaker button over and over and they can hear me for 3 minutes then it goes out again and I have to do it again and then they just give up and hang up. What kind of phone is this where people can't hear you???

I was on the phone with both AT&T and Apple. They told me to take it to the Apple store to the Genius Bar. The guy ran all the tests and said everything was fine but he saw I had had a lot of software crashes so he recommended a software reset. He did that and that fixed it for like 8 days then the problem came back so I did what he recommended and did a hard reset and did a restore from iCloud. That didn't fix the problem.

Made another appointment, went back, they gave me a replacement iPhone 7 Plus. Same issue. Did all that for nothing.

This needs to be fixed.

I'm having the exact same issue with my iPhone 7. I've already swapped it out for a replacement phone and it did not fix the issue. I had my mother record from her phone our conversation so that I could understand what is happening. Basically the microphone goes in and out and I sound garbled so she can't hear me. It happens in different locations and with different people who all have the same complaints. It's awful! I've had nothing but trouble with my iPhone 7 (7s... two phones so far) and I've never had any issues with any of my previous iPhones. I have told numerous people not to upgrade to the iPhone 7 until they can sort through some of these issues. It's been an absolute nightmare and I have logged probably over 20 hours of problem-solving trying to get my phone to work correctly for other issues too...with no luck. I am so frustrated and I'm ready to switch to an android. Apple seems to be going downhill...

New iPhone 7 Plus on December 23rd. Called family on December 25th, and after a minute of talking, they could not hear me anymore. I worried I'd somehow hit the mute button with my cheek. I called back, talked for a minute again, and then again they could not hear me. Repeated five times that day, and each time but the last the audio drop occurred. Thought it might be their phone (a cordless landline). Went two weeks making few calls, but no problems. Today, made a call, and after a minute or so of talking, my audio cut out again, and they could not hear me. I could hear them fine. Hung up, called back, all was well but I kept the call very short.

So, as far as I know, there's no audio quality issue, just a complete cutoff of my audio going to the person I have called.

Very frustrating. Thanks for this thread. I'll know not to bother getting new hardware. Hope they fix it soon.

Danny.

(Update)

Okay so I discovered another issue that interrupts the mic and phone to ear speaker with incoming calls, I'm sure I'm not the only one that gets custom ringtones and since there are a few songs i like, I download them and use them.

A few days ago I decided to use one of these ringtones and set the volume high so that I can hear it ringing through my purse/messenger bag, I get an incoming call the ringtone is playing normally and I answer it and all I hear is silence. I checked the phone to see if the caller hanged up and no the call still appeared on the screen, I then tell the caller that I can't hear them and I'll call back. I did call them back and the phone call went well and the caller told me that during the first phone call I sounded muffled.

About 2 hrs later, another call and the same problem so I asked my mom to call me and I noticed that the phone to ear speaker plays the ringtone just like it does when using Music and other music apps. So I came to the conclusion that somehow the high volume was interfering with the phone calls and decided to check if I was right, I lowered the ringtone volume to half and had my mom call again and I answered, no issues at all I could hear my mom on the line and she could hear me clearly.

We really need an update to fix these issues Apple.

I had this same issue with my iPhone 6s nobody could hear me I had to use speaker phone and that didn't work all thr time either,so I gave up and had people text me when possible. I am now after a year so use to to not talking on phone that when people ask if they can call me I cringe..This does need to be fixed people think I am antisocial lol

I have the same problem with 7plus (tmobile). I replaced my phone in apple store, but no use. Everyone complaining about my phone they are not hearing properly and voice is getting fluctuated and breaking some times. I am really disappointed with this.

Hi,

Last week I made some progress with Apple on this annoying issue. Let me update you all on it.

The senior Apple customer service guy contacted me again. He informed me that the Apple engineers are studying the video of me as a user, demonstrating the problem, that I had made over FaceTime with the Apple customer service guy recording it et cetera (read about any details in previous posts here).

Recently I was contacted again and he asked me to install a by Apple engineering specially written piece of software that was sended over by him to me, to be able to monitor and log the iPhone's functions specific to this issue while making calls and recreating the problem. Because it already showed that it's easy to recreate the problem as often as I want (read about those details also in previous posts here).

After installing this software and having it activated I was with him on the phone, and created the problem 5 times during the call while he confirmed every time that the sound indeed dropped on his end and came back again when I was 'undoing' it. Then we ended the call and I needed to wait 15 minutes. Then I had to press a combination of buttons (sound buttons both at once and the off button accordingly) and the iPhone would vibrate and I had to wait another 15 minutes as the iPhone was then compiling the log-file (based on this installed piece of Apple software).

Then he called me again and I did this whole process again of calling & talking while creating the problem, pressing buttons for compiling the log file after 15 minutes. And also all that for a third time.

After that we had 3 log files. Via iTunes I synced theses files with my Macbook Pro - must be said with his good guidance via phone - including quite some supporting files so it seemed. I zipped this total package (ca. 800 MB).

Then I received a link from him over email. I opened that and I had to log in with my Apple ID and dropped the zipped file in a box and then it was all transferred to Apple engineering.

The senior Apple customer service guy confirmed me later over e-mail that all was received by Apple engineering correctly.

I will be informed wednesday 11th of January by him if Apple engineering has found the problem and/or what any possible next steps will be. It can be that they have full understanding now and can tell me what's wrong and correct it instantly, or that it's going to be fixed through an update or that further research will be required. I volentarely offered to come to California any time when required. 😀

I think overall by service, Apple is still amazing. Because it's taken care off very seriously by this senior customer service guy. He's most professional in handling this. And on this service level they absolutely do their best to understand it, as it is a bit of a 'crazy problem'. The Genius bar in the Apple store was not that perfect I must say, I think that bar is not as 'genius' as claimed. They mean well but that's it. But these senior Apple customer service guys totally are top notch!

When they fix this seriously frustrating issue of the iPhone7, it will absolutely be my most favorite smartphone again. 🙂

As said before, hang in a little bit longer. Help may be on the way. Thank you.

Hi mr.aam,

I went through the same process with an Apple support Thursday. I know people wants a quick fix, but if you don't know what is causing it, especially when it is happening to random people, it is going to take awhile. Hopefully they will get enough information from the people that has contacted and run the test to come up with a solution.
