iPhone 7 Plus Phone Call Sound Quality

So we just got 2 new iPhone 7 Plus' and I am noticing that the incoming call audio quality on both sounds strange. I have the Apple leather case on the phone and incoming audio sounds distant. Like it is coming from behind the phone or something. It almost sounds like the phone is on speaker phone but it isn't. Turning the volume down helps a bit but it seems off. Previous I had an iPhone 6 so I don't know how this compares to the 6 Plus.


Any help is appreciated!


Thanks!

I found the solution: The phone was still wrapped up in the original plastic it came in, and that plastic was making the phone sound echo in a strange way. Hope it helps you too! The sound difference without that plastic wrap is massive.

Actually, It turns out after lots of investigation and replacing the phone three times, its the folio cover. I tried the tape with the folio cover and it improved slightly according to others, but the most significant improvement is completely removing the phone from the folio cover. I'm returning the Folio cover and going back to open face leather cover.

I tried all that You just said, and nothing helped, but...i replaced sim card from 4G to old 3G, and YES it sounds perfect with 3G old sim from the same carrier.

The problem is with cell modems that Apple installs into phones. There are two kinds - Intel and Qualcomm and their relation with the carrier signal. Qualcomm modems are much more better than Intels (specially with smaller antenna area on newer iPhones).

Now sound is perfect, and everything else but internet speed. I am always connected on 3G network instead on 4G. That would be fine, but I am just a little bit frustrated that I can not use 4G speed.

THERE IS NO OTHER SOLUTION. Apple must stop using Intel inferior modems and solve the court problems with the Qualcomm (or just buy them).

Calls to call centers are often heard clearly because they're using VOIP (voice over internet protocol) I also had a phone replaced twice so after 3 cell phones doing the same thing - we figured it out...

Well, a lot of users in a lot of threads have reported that changing the case has resolved the problem. So, while it may not be always, it's a simple thing to try.

I’m in the uk on the 3 network, having purchased an iPhone X I’m finding exactly the same problems with audio on phone calls while using the handset earpiece as previously mentioned by fellow users of the 7, 8 and X series iPhones.


When I had my IPhone 6+ I would talk frequently with a friend who was using a 7+ many a time his voice would fade away unless he spoke directly into the phone, he on the other hand had no difficulty hearing me while both of us were using the earpiece.


This problem to my thinking is a hardware issue, mic, earpiece or both because if it could be rectified by a software update, don’t you think it would have been addressed by now - I do.

These devices are incapable of performing their most basic function - phone calls without issues, they are even supposed to be VOLTE capable, you would never think so, it’s like taking a step back in time from digital to analogue audio.

The best audio seems to be available when you are using your 7,8 or X series handset with a car system or Bluetooth device, AirPods for example although even those have issues such as wind and background noise because they do not have a noise cancelling system.


Ill be returning this, my second iPhone X for a full refund, phone and case and reverting to an older model until I can find a suitable alternative having become increasingly dissatisfied with the brands recent compromised offerings.

I had this issue with the 7+ and now the X, I'm convinced it's related in some way to the rear mic. It happens when the front cover is moved to the back during a call. My case incorporates the sleep wake function which I want to use to extend battery life so leaving it closed during a call isn't an option as it puts my X to sleep and kills the call. When I receive a call I fold the front cover to the back with my finger between the two leaving a gap which seems to allow the rear mic to do it's job, callers tell me it works.

Like many here, I’ve gone through 3 iPhone 7’s, and tried absolutely everything to no avail. It can really only be a hardware issue, whether apple will recognize it or not.


I finally gave up, and paid for a 6s out of my own pocket, which I’ve been using for over half a year and it has functioned perfectly all along.


I’d be interested to learn whether the outgoing sound issue has finally been fixed in the iPhone 8 and/or X. Anyone?

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!
