iPhone 5 bad call voice quality

I have a verizon iPhone 5 w poor voice call quality. It sounds digitized. ESP w another verizon call. Turning Lte off makes no difference. I am going back to my iPhone 4 tomorrow as that I cannot hear/understand most calls and back to AT&T. I just wish the us carriers would support the hd audio/ wide and audio feature. In the uk where they do support it people are raving about it. we need to lobby for it here. The carriers here are more focused on other things than voice call quality but to me that's the most important aspect of a telephone. VoLte is supposedly not supported by the iPhone 5 which was a disappointment. Sprint supports hd audio but they announced the iPhone Is not supported so that's why I'm going back to what I had until it gets worked out.

Went to Verizon to get phone serviced. Sales rep was not very helpful and asked me to call VZ customer service to have phone network checked. Did a network reset on their end, but no improvement in call quality. Even when I place a call the ring sounds like it has a bad connection (static in ringtone). Phone rep was very helpful at VZ and called 2 other Verizon stores and Apple to see if they had any replacement nano SIM cards, but all stores were out of stock. Ended up returning Iphone 5 and going back to 4S. Disappointed, but phone call quality is most important function of my cell "phone". Possible just a bad device or SIM card.

Has any one noticed a difference with or without a case? After a day I stopped using my case and now that I think about it that's when I started to really notice the issues with call quality. I'm wonder if it might have to do with antenna interference similar to the problem they first had with the iPhone 4.

I have also had the robotic digital call issue. I sound fine to the other person, but they sound like a computer / alien to me. I'm on uk Vodafone so 3G / GPRS. Happens regardless if I'm on wifi or not. Only noticed it on incoming calls. These have all been from my wife using an O2 uk iPhone 4S

Same problem. Let's all provide our info for troubleshooting.

Phone: iPhone 5

Carrier: Verizon (in an area with supposedly good LTE strength)

Network: LTE, 3G... doesn't seem to matter, voices are often auto-tuned!

Hopefully with enough data from those who have problems, Apple can figure out what to fix.

I'm guessing / hoping it's a software issue

iPhone 5 w/o case

AT&T 4G (HSPA+)

Extremely poor call quality (robotic, muffled, digitized) with both incoming and outgoing calls. The other end of line has no problem with call quality.

Phone: IPhone 5

Network: Verizon

Location: Atlanta, GA (Strong LTE Signal)

Issues: Auto-tune/Robotic/Static calls. I can not understand what the other person is saying. Both incoming and outgoing calls. Same with LTE On or Off. Same with WIFI On or Off. Person on other end of the call seems to hear me ok/minimal issues. Not using a case on IPhone 5. Went back to IPhone 4S.

Yes, I too have found the call quality to be akin to low frequency satellite radio signals- digitized and choppy.

This iPhone 5 being my 1st smartphone, I thought poorer call quality was natural...

I really hope Verizon or Apple can resolve this...If I can't get decent reception, I'll just go back to a flip phone...

From what I've read in this forum, and my personal experience with iPhone 4 and 4s, all 3 of these models need a case to take care of the static/poor quality/etc....

I've had a case on my 4 and 4s models since I got them, and took off the cases to double check today. Without the cases, the call quality is completely unacceptable compared to having the cases on.

This is with ATT.

From what I've researched the “antenna” was completely redesigned in the IPhone 5 preventing the need for a case/bumper or the infamous "death grip" problems with the IPhone 4. I don’t believe this is what has been causing the problem with call quality on the IPhone 5.

I agree. It's not a signal issue. It sounds more like an encoding / processing glitch. The sound is clear and crisp, just sounds very strange and monotonous.

So what do we know so far?

It happens in uk and USA across multiple carriers on LTE and non LTE. Replacing the phone / sim doesn't cure the issue. The issue is intermittent, at least for me. Most calls are ok.

I have tipped modmyi.com hopefully they will cover the issue. Once the blogosphere get their teeth into this it may bump it up apples radar.

My Verizon iphone 5 has consistent problems with others in this thread: choppy, auto-tuned sounding voice for all calls. If my business client on the other end of the call is using a speakerphone, his words are garbled or drop out. I have used AT&T iphone 3GS for 3 years without these problems. The iphone will be unquestionable returned if the issue is not resolved soon, the voice calls are THAT bad.

I'm having the same problem using a Black 32 Gb iPhone 5 on the AT&T network near Atlanta. People on the other end can hear me fine, but I can't make out half the words they're saying. I've had to disconnect and call back from my office phone on numerous occasions. Turning on/off LTE or WiFi has not had a noticeable improvement. I will be going back to the 4S very soon if this is not quickly resolved.

Also having autotune issues. Driving me nuts because I love the iphone 5 otherwise (on Verizon). I did switch from AT&T (and an iphone 4) and I thought it was a Verizon v. AT&T thing. Seems like it's affecting both carriers.
