iphone 8 poor/sensitive mic during call

Hi all

I've been in IT for 20 years. Just gave my son an iphone 8 for Christmas and it had the "mic issue."

Read through the forums and this isn't a hardware issue. Process of elimination makes it clear it's affecting too many diverse pieces of equipment and different equipment batches to be a hardware problem. Further - the problem only exists on the Apple Phone app. 3rd party apps don't have the issue using the same physical hardware, case, etc.

It's a software issue. Having been in networking and Cisco IPT for a long time - listened carefully during test calls and the voice was clear if shouting or in loud environments but crappy in quiet or normal environments. This points to one thing - noise cancellation and an overaggressive codec involved. Cisco had a similar problem a few years back when they introduced a new HD codec.

Solution - upgraded to the latest 11.2.x release and turned off noise cancellation in Settings > General > accessibility

Instantly the crappy mic worked perfect. Being that it is a software bug -- it's possible that the codec might drift and the crappy mic comes back. In that case you might have to turn noise cancellation back on for a few minutes and then off again -- or reboot your phone.

It's a pain but I can tell you as an IPT professional -- I'm 100% sure this is a software bug.

Apple -- I know you are reading this -- get your engineers to fix it. Please.

Most people in this group that trade in their phones for new ones don’t get any relief. I assume the cause is coming from configurations on my phone such as a combination of apps or network settings.. Just a bad luck combination

If you read through this entire discussion group, the issue is affecting iPhone 7's, 8's and X's

It's affecting people across multiple regions of the world. It's affecting those on iOS 11 specifically.

All that adds up to it's not hardware -- it's statistically too broad -- it's software as previously described... a misprogramed driver, codec, etc that is overaggressive on noise cancellation. Turning off noise cancellation and updating to the latest iOS seems to resolve it in a workaround way.

Interestingly before iOS 11 the default was to have noise cancellation turned off. In iOS 11 the default was to have it turned on

If you are reading everything you will see that updates and noise cancellation adjustments don’t work. The other microphones work better than the main apple microphone but it is because of software not hardware

When I use Snapchat on iPhone 8 to call or to video call in SNAPCHAT

, the phone’s screen turns total black, like it’s shutdown and back on to Snapchat, like on and off, on and off. When it goes black, I have no control of it unless I cut the call or FaceTime call in SNAPCHAT or turn off the phone.

Hello,

I have also had this problem, my iPhone 8 has just come back from the apple authorised repair facility.

They inform me that they have performed extensive tests and found nothing wrong. If I find that the problem still exists (it does) then to reset the phone to its factory settings and set it up as a new phone without using a back up. I have not done this yet but plan to do it at the weekend just to see if there is something corrupt in my backup.

My back up has been used on various through the years and I can only assume that the repair facility believe it is corrupted in some way.

Is there anyone who is experiencing this microphone problem that has set up their phone from scratch? (Without using a backup saved in iCloud)

Hello Stockholmred

I see the problem that when you calling and the sound not well right? You were sent to the Apple warranties and then it comeback they said Meditate no anything else going wrong. So with my experiences that you should try to change your Wifi internet modem.(Maybe the modem out of date or any mistake) And make sure your data always backup in the icloud storages. Sometime If the icloud full you can be able delete them to free your storages coz everything you saved there it were recognize and remember. Dont worry.!! (SIS- intelligence)The icloud should not be too full with warning system annoying. Because These action status sometimes affectted to the data sound voice call or your Media sound also.

Goodluck

I did factory reset and problem went away until I reinstalled my back up. I must have my back up because I can’t lose my text message history.

They keep giving me recycled useless suggestions to fix this problem, today they told me to wear a tinfoil hat.

I got my iPhone 8 about a week after they hit the streets. Same problem with the microphone & low volume on phone calls unless using the speakerphone.

Very unhappy with the performance of the phone in this regard. Too bad my iPhone 6 has a battery that only lasts a couple of hours off the charger or I would return the 8.

The problem seems to be with sensitivity of the mic. Cancelling "noise cut off" in general/accesibility/noise reduction improoves this issue. So the problem might be solved maybe in the soft... Why do we pay for devices as beta testers? Next move should be on our side as a class action lawsuit

Yes. I hate this phone with every fiber of my being. I am also on iPhone 8 number two and NO ONE CAN HEAR ME. I work as a personal assistant, so this is especially frustrating. Have you found a fix?

There are many of us with this problem. It’s nig the WiFi or router- it’s the phone itself. The microphone cuts out- unless you hold the phone perfectly still and shout it sounds muffled to person on other end. You can reset the phone, exchange it, bring it to Apple store, change settings etc and it’s no good. There are so many with this issue. A response from Apple acknowledging that indeed there is a problem and they are aware and working on a solution be it an update, new mic repair, recall, whatever. But it seems we are all being ignored or fed a line to reset the phone or check settings or call WiFi company. This problem occurs in just plain old talking on the phone. Which should be working! I bought a $1,049 256gb iPhone 8 Plus, I shouldn’t have to put earplugs on or use speakerphone as the only way to make calls that people can hear me. Apple please promise us a fix is in the works. Thank you.

Yes, same here, this is my 2nd Brand New iphone 8 Plus and reading all these posts, everyone is getting new ones and then another new one replacing the first one, etc and having the same issue. I also hear everyone trying to go to Apple Stores and standing and dealing with this issue for Hours and Hours and they really are not getting the results they wanted. So, why go into the store if i'm going to have the same experience. Apple needs to get this solved Now! These phones are expensive and I too, use it everyday and need it to function as a basic phone, Apple is ignoring this problem. My word , put a software update out that actually will help us fix the problem. I have tried everything suggested on this forum and Zero have fixed the issue. I hate always using my speaker phone for a call. I dont want others to hear my conversations from the person on the other end of the call. Apple, Address this issue Now and Fix It Now. Apple is monitoring these feeds and comments. Trust me they are and they are aware of the issue, we just need to get a Fix for it. I have such delays on sending pics via texts too. Select a pic and then go to a text option and the phone just sits there and sits there.....its like its frozen and then, no joke, 15 - 20 seconds later it moves to the text contact screen... Its really getting annoying. All my calls, I hear "I cannot hear you" " You sound like you are in a tunnel and its garbled and cutting out"...Ridiculous. $1,000 phone doesn't work. I need it to work everyday and on every call. Apple, do let us know what is going on. Thanks everyone for all your comments and opinions and suggestions.
