Iphone 8 voice quality issue

Not sure if this will help anyone else, but Apple Support solved my particular issue: I bought a new iPhone 8 Plus and started testing it and found that my voice quality was sounding very muddy/muffled to the person on the other end of the conversation. It was unacceptably bad.

Called Apple Support. The iPhone 8 Plus had IOS 11.4 when I took it out of the box and I had upgraded to 11.4.1 as part of set up. The Support person asked that I first back up the phone, then, using iTunes, Restore it to factory settings, re-install 11.4.1 from scratch, then restore my back up. I did all that via iTunes on my Macbook Pro (not believing it would help.) Then after all that (which takes awhile) he called me on my iPhone 8 Plus and stated that my voice sounded perfectly clear to him. I still wasn't confident that the software was the issue but sure enough I have retested it and the sound is definitely much clearer now.

My suspicion (and his) is that my upgrade to 11.4.1 was not truly successful and by going all the way back to factory settings and then reinstalling, the issue went away.

Looking back, that actually seems more likely than a hardware issue, so I really am glad I didn't just return the phone for another (one which could have had the same issue with software.)

We have an iPhone 8 plus on Verizon with the same issue of people we are talking to, complaining of muffled audio. My daughter also has the iPhone 8 plus, living in a different city, and when we talk to each other, we have been arguing about which phone or cell location is causing the audio problems. We both have noise cancellation enabled.

I just got a new iPhone SE yesterday, with iOS 11, on Verizon, and today, a customer said the audio was not clear at various times during the call. ( noise cancellation enabled). I took the phone out of the case to make sure the case was not interfering with the cell signal or microphones. Before the iphone SE, I was using an IPhone 5 running iOS 10, aith noise cancellation enabled, and had no audio complaints during calls.

We are turning off noise cancellation on all 3 iPhones to see if that corrects the problem...

Could the problem be iOS 11?

I have had these same issues with the IPhone 7plus.. I was going to upgrade to the 8 plus... oh me. I’m nervous now.... the 7 has had known issues with call quality. I wonder if this is becoming a trend? My iPhone 6plus was awesome. It just needed a battery.....

I have T-Mobile and I am having the same issue. I am going to go back to the T-Mobile store to see if they will exchange, before trying Apple. I originally thought it was just my father’s phone that had the problem, since he was the only one complaining, then recently my wife and my brother both made the same comment. I just bought this phone less than two weeks ago, and kind of disappointed that it has this issue.

I’m also having the same problem if not being able to hear people well because they’re so muffled, yet when I call back on FaceTime audio they’re very clear. Only happened since I got my 8+ also. Could it be an issue with cellular voice processing or something. I have 4g voice and data selected and did on my 6s also so it’s nkt that either.

Thanks, but if I have to take off the case every time I talk to someone, that’s not very convenient. Time to go back to the store. Might get a Samsung (and give Apple a vet poor rating)... if they’re not interested in fixing the problem or helping people who spend lots of money on their products, then they can stick their $1trillion up their...

I, too, am having this problem. It is particularly discouraging because the date today is July 12, 2018, and I see you posted Sept 25, 2017. So it's been a year and nothing is being done about the issue and these phones are being sold with this known problem. Disgusting. I have been to the Apple store and changed SIM cards, etc. All the things you speak of. No improvement. In fact, the muffled voice on mine is so bad people have to call me back on my land line!

Have finally solved the voice quality issue on my 8 plus. A tech at Consumer Cellular found the solution. Go to Settings, General, Accessibility, then under hearing, turn off Phone Noise Cancellation.
The other thing that also improves the quality is to turn on Speaker

My issue is about half or more than half of incoming calls sound broken up on iPhone 8 with Sprint while LTE is on. The other person hears me fine but I hear them breaking up as soon as I answer the call. I tell them to hang up and call me back, then phone call voice is fine. If LTE is off it will go to 3G and no voice issues. Also no voice issues while at home and using WiFi calling. I know of someone who has iPhone X on AT&T with the same problem as me. Looks like definitely a problem with LTE specifically on iPhone 8 and X. Sprint even changed my MSID since I saw on Reddit someone saying that this corrects the issue, it worked a few days for me but back to square one with the same original problem even with MSID changed.

I am on Sprint and have an iPhone 8+ for about 3 months now. Just recently people have been saying they cannot hear me and that I sound like I'm "underwater". I upgraded to iOS 12 because I hadn't done that yet, that didn't help. I turned off noise cancellation which seems to be working for now but I just did this an hour ago. I use my phone for work and cannot be breaking up or sounding like I'm underwater for customers.

I hope apple fixes this issue because it's serious. You have over 6 pages of complaints over the last year with the same issue on the same phone across different networks. Please look into this apple.

Zagg has a lifetime warranty so go to zagg.com and register your purchase then when you remove the screen cover it will break and you may claim it on zagg.c

om. They will send you a new one for postage only around six dollars. I always buy zagg for that reason. Good luck.

Apple has replaced my iPhone 8 three times because of the audio problem everyone here is experiencing. The sound is horrible. I bought the phone in January, 2018 for $700. I am glad I purchased the Apple Care as well. After 3 new phones I have the same problem so now Apple is blaming Verizon. Verizon takes no responsibility for the poor audio so I am stuck with a lousy expensive iPhone that I would never recommend to anyone. My friend has a $15 tracfone that has wonderful voice quality, guess I should have saved some money. when it's time to get a new phone I'll shop around.

Not true, I am with Verizon on my 8 Plus. And just like my 7 Plus. People keep saying, either they cannot hear me, or there is a lot of static.

I find the calls from others are crystal clear.

My iPhone 6 gave me zero problems, I am wishing now I didn’t trade up to this phone.

Starting to think it’s time to jump ship back to Android.

It’s hard to hear on my phone have to use speaker which is annoying

I'm getting the same issue. People can't hear me or they say I keep breaking up. FaceTime video is great, but the voice they say is still awful. Any luck resolving this?
