iPhone 5 bad call voice quality

Has anyone been able to debug this further.

For those of us on Verizon wireless we received a carrier update this morning but that did not fix this.

For me the call quality is not totally unacceptable but it is robotic and has some static in it. It is definately very clear if I take the call on the road where the interference from wifi is low.

At home or in the office where there are wifi routers it is mufflled but only slightly.

I can confirm that this problem also occurs in Norway. I have exactly the same symptoms as many other users in this thread. I started a thread in a Norwegian Apple-forum: http://ipod1.no/forum/viewtopic.php?t=282192, and replies from other frustrated users are ticking in.

I really hope that Apple can fix this as soon as possible, and that this problem is software related, NOT hardware related.

Same issue here in Germany... many iPhone 5 user are reporting this problem in different Bords... seems to be a global phone related bug!

Guys

I opened a bug on the developer portal for this bud id is 12421948

I would encourage all of you to do the same. More the number of people report the bug the more probablity we have of getting attention from Apple.

I am surprised that the thread is still 7 pages long. I hope thi sis software related and we are not a batch of unlucky guys with bad hardware.

Here is the text of the bug I reported

Summary: Most of the voice calls from iPhone 5 experience a robotic voice from the remote party.

The voice fells like as if the remote person on the pone is in a low sign while he is not.

If called from an iPhone 4s this does not happen.

It happens mostly where there is a possible interference from WiFi networks. Calls on the road where there is no WiFi or network interference seem clear.

May be something related to the antenna software of noise filtering software

Steps to Reproduce:

Place a voice call or receive an incoming call on iPhone 5 while at home or office.More than 50% of the calls have this problem

Expected Results:

Clear voice

Actual Results:

Muffled , Robotic voice

Regression:

Notes:

I have the same exact problem, actually before I upgraded to the Verizon fix for the usage issue that has come out I did not have this problem, now within the last 2-3 days approximately 70% of my calls I cant hear a thing the other person is saying, while they can hear me clearly. And it seems to be more prevelant when I call another Iphone, like my girlfriend on her Iphone 4s last night I could not get through to her at all, but when I dialed my work line it went through without any problems, and if she called me the same problem happened, I had to switch to a landline to make calls? Apple can you please address this problem as it seems to be getting worse and worse, I made an appointment at the Apple store but judging by the responses even a new Iphone 5 wont help. The worst part is I switched from a 4s on Sprint which had great call quality to an Iphone 5 on Verizon that has the worst call quality, but certainly can get a faster internet connection with LTE.

Edit: After looking around this is probably caused by the carriers not supporting LTE and voice calls at the same time? The phone does switch from 4g as soon as you make a call and goes back to LTE, maybe it is not switching over quickly enough, although this problem is persistent even after making multiple calls or switching off LTE? I mean I know the Iphone lacks the ability to have an LTE and a non-LTE signal at the same time, but then AT&T phones should not be having this problem? I really hope it is a software issue and not a hardware issue..

Same problem. here's a bit more research though.

Verizon iPhone 5 - Carrier Update Installed.

I have the problem whether on LTE or 3G.

Handset, headphones, or bluetooth.

Problem experienced in Chicago, Detroit, and Washington DC.

Here's the interesting thing.

When I call anyone who uses VoIP, its worse. One of the buildings at my work migrated to VoIP this year, and another site did not. The VoIP site is FAR worse. Similar with calling into a conference line or any other place which uses digitally compressed calls. This stands out to me - the compression used in the iPhone 5 might be causing the issue.

I did not have this problem on my iPhone 4 with AT&T and IOS6.

In the meantime, Verizon is sending me a new phone.

Same problems. In Seattle. Switched from iPhone 4 AT&T to Verizon iPhone 5. Sound is particularly bad on BMW bluetooth. This was NOT a problem at all on old phone. Sounds robotic, like it's going through VOIP. As if it doesn't start transmitting until it senses sound, so you lose the beginnnings and ends of the sentences. We moved 4 phones from AT&T to Verizon. Wife moving back to AT&T and 4S. Hope this is software!! Surprising this thread is 7 pages and no comments from Apple anywhere.

Just went to the apple store, was a hardware problem for me, switched to a new iPhone 5 and now I have no problems at all, was kind of lucky they had replacement phones in stock, and apple care was awesome

This is an update went to the apple store and it was a hardware problem with my iphone 5 was given a new iPhone 5. I was informed that it was a hardware problem not a software issue. If your not hearing the person on the phone or the person states they can hardly hear you call your service provider. I could hear them perfectly and they also could hear me perfectly over the speaker phone only, but once I disengaged the speaker it was the same issue. Apple was awesome and swapped it out. I have ATT so I'm not sure how the other service providers work, but goto the Apple store so they know its a on going problem and will take care of those having this issue. My iphone 5 has been working perfectly so far, but was advised to return if the issues arised once again or I had any other iphone issues... good luck guys.

I have this same issue now in Finland with Sonera as the carrier. I didn't notice these issues when I got my iPhone 5 last week, but now that I've got a case, I've experienced robotic and choppy voice from the person I'm talking to, but they're still hearing me just fine. Maybe I'll need to try without a case.

I'm having the same problem. Especially when calling my brother on US Cellular. I have Verizon LTE and the audio is choppy and robotic sounding and a ton of dropped calls and then the phone displays the infamous "Call Failed" I feel a class action lawsuit a-brewing. Apple if you're listening fix the problem or I will drop my plan and this phone it's absolute BS how much the month service costs and the cost of the "best iphone yet" fix it or android here I come.

Took iPhone to apple store. They did diagnostics and all appears to be working ok. Removed the case and have had some noticeable improvement for Bluetooth. We shall see how this resolves.

Just to follow up on my previous posts. I made an appt at the Genius Bar today. Of course I could not reproduce the problem there, but they gave me a new phone nonetheless. I have not experienced any of the poor voice quality on the replacement phone while at home or at my office (the 2 places where it was worst). I would strongly encourage anyone experiencing this problem to get a replacement phone. It certainly seems to be hardware related in my case.

Follow up on my post as well.

I didn't really believe this was a hardware issue so I wasn't really holding out hope it would be resolved by getting a replacement phone.

Well, it was.

The voice quality IS better than on the 4 - by a noticeable margin.

And my reception is better.

But it has a different speaker problem.

C'est la vie.

So for those of you that went to Apple Store and got phone replaced did you also get new nano sim? I went to apple store and they replaced phone but kept original sim. Wife still having issues.

I have 32Gb Black iPhone. LTE in most areas I travel but 3G in hometown. Use WIFI at home. No issues at all.

My wife has bad sound and "Call Failed" quite a bit in all areas WIFI, 3G and LTE area. VZW said avg call fail is around 2.2 and hers was at 6.4 from 9/22 on.

Phone with issue:

Verizon

White iPhone 5

16GB

On our second phone. Have done restore from iCloud and clean install on both to no avail.
