iPhone 7 Plus Phone Call Sound Quality

I have the same issue with iPhone X: I turned off noise cancellation and this sis not improve issue. I have also performed all of the following isolation steps along side Apple at the McArthur Center Apple Store.

iPhone x - People constantly complaining the voice quality is muffled or very low when using phone to ear without bluetooth

People tell me they cannot hear me on my new iPhone X. I've performed so many isolation steps and even exchanged my phone, and nothing seems to help. I've tried so many things to isolate the issue.

Initial steps performed:

1) Erase and reset phone to factory software

2) Reset Network settings

3) Noise Cancellation Off

4) Restored iPhone as new without any previous restore from iCloud

5) Taken phone to Apple McArthur store and have them perform all of the above steps again and also install new software from iTunes

6) Tried phone with Apple Folio cover and then without Folio cover

7) Carrier = AT&T

- Asked carrier to reconfigure phone to network

- Replaced SIM card and had carrier reconfigure to network

- Turned off AT&T features

- Cellular Data set to data only

- Cellular Data set to Voice and Data

- Typical signal is 5-6 bars LTE when this occurs

8) Replaced iPhone X, Same issue with new phone

Additional steps performed:

7) Performed Voice Memo Recording

1) Recorded voice with Apple Folio Case - Result Clear Sound

2) Recorded voice without Apple Folio Case - Result Clear Sound

My Conclusion: There must be a serious bug in the new IOS 11 software causing this issue. I've been reading that a number of iPhone 7, 8 and X users are complaining about the same issue. The muffled voice is so bad that IVR systems and even people on the other end of the phone simply can’t understand what we're saying. If you change the phone to communicate through Bluetooth or simply put on the speakerphone everything is fine.

Please fix this issue. The battery on blue tooth doesn’t last long enough and often times we must use the phone up to our ear and mouth.

I tried mine without a case, still had the call quality issue. I am hearing it's much worse on AT&T than it is Verizon, I am on AT&T.

There is another solution if you are correct about the modem. Apple sells unlocked GSM/CDMA versions of the iPhone that has the QUALCOMM modem, it will work on AT&T or Version/Sprint, etc., the downside is you cannot get one from your carrier that is multi-network usable. Or you could change to Verizon for your carrier because the intel modems will not run on a CDMA network, all iPhones on Verizon or Sprint must have the Qualcomm modem. Not an option for me, where I live only AT&T works, I’m thinking about buying the multi-network version from Apple.

Assuming that Apple replaced it, what did they say when you contacted them about the issues with the new phone?

I’ve tried lots of times without a case, no change, my case doesn’t cover the rear microphone

Sent from my iPhone

Just sent in my Iphone Plus 7 for sound quality problems in calls and even for music it sounds so cheap. They "didn't find any problems". Not sure what to do. I have a 250 euro phone that sounds much better than my 900 euro Iphone 7 plus. I feel ripped off badly.

From the uk.

Having spent £1149 on the super shiny, super slippy iPhone X it deserves to be protected and what better than a case from the phone manufacturer, so let’s throw another £39 at protecting it and get the silicon case in white, there we go - lovely.

The case does not obstruct the mic hole on the back between the two camera lens but as people are reporting and as I have now tested and proved for myself, covering it with my finger while using the phone in normal set to ear mode does actually improve things for the person on the receiving end however the silicon case is also not without issues where pressing the single side button does not respond, a second press takes you straight to Apple Pay and that is why the first iPhone X was replaced, my friends iPhone X exhibits the same issue with his silicon case too. Five items with issues - we’ll done mr cook.

Upgraded my wife’s and daughter’s iPhones to iPhone 7 at the same time - one gold one rpose gold. Daughter’s, rose gold, no problem. Wife’s, gold, she says I sound far away-in a tunnel. I hear a crackling scratchy voice. Not happy!!

😕 Unless as Tracy states you aren't using a case. Unless there's a very clever invisible apple case I don't know about 😉, then mines got same issue as many others report. Anyone I call reports distance and echo.

Cases may be true for some but most definitely not all.

First, make sure the plastic covering on the display to protect it during shipment has been removed. If you have your iPhone in a case, try removing it and making a call. If you still notice the volume isn't quite where it should be, use the steps in the article linked below for further assistance.

If you can‘t hear a person on a call or voicemail or if the sound isn‘t clear on your iPhone

Check my below answer and see how it works out for you? :)

Apple has an issue which they have no fix and they are certainly not going to destroy the inferior model. I am to the point where there should be a class action lawsuit against them.

My iphone 7 plus was working perfectly just had some battery issues and now got replaced with new device but this one is again acting weird.

Being stuck 2 times today and had to force restart.

I'll try the tape recommendation above and circle back to see if this resolves the issue.
