iPhone 5 bad call voice quality

Same issues 32gig black in Canada on Telus. I sound fine to the other end, but the incoming sound is muffled and quiet. The headphone make it better.. but it's still not as good as my 3GS.

Come on Apple.. this is obviously a real issue.

I'm having all of these same issues! so frustrating.

T-mobile

iPhone 5 32b

Same here...

"I had left the plastic screen protector in place that came with the phone as delivered because I hadn't had time yet to put an "official" screen saver on it. When I removed the plastic, everything worked fine. The faintness was gone as was the tinnyness."

Yes, the plastic protector must be removed before you use your iPhone 5. Since it covers the speaker, you will get a muffled, low volume sound if you don't take it off. It was not means to be left in place. It just protects the phone from damage durning manufacturing and shipping.

I was having all of the same voice quality issues and when I went to my Verizon store their tech support reset the voice software by pressing *18 on the phone and the problem was resolved.

Replacing the SIM did not help - as expected. Got Optus to agree to file a Problem Reeport.

Hi,

Same problem here in France with Orange provider.

Iphone 5 32gb

My workarround is to switch LTE off in Setings->General->Celular. Once LTE is off, all calls come through clearly and first time.

Ok guys i think i have found a fix to this issue. I have a black 32 gb iphone and am based in the UK on vodafone and have been experiencing this same problem since day 1. i have changed the hand set 3 times and no joy. Last week i turned my phone off, took out the sim, re-inserted the sim and then reset network settings. This seems to have fixed the problem. Please let me know if this works for you - ill update you guys in a week to say whether its definately worked !

I have done an investigation and published it in my column at www.sddt.com/phil. One think I learned are the Bluetooth headset companies are finding problems with their devices working with the iPhone 5. It's a result of changes to Apple's noise cancellation chip and algorithms. My iPhone 5 (Verizon) has suffered from many of the problems I reported here. My conclusion is it is a hardware problem that Apple needs to fix. One of the unintended consequences of Apple not sharing their new products with other companies before introduction is that we are left to discover the problems that they didn't or didn't have time to fix.

I am on 3 network in UK and I am experiencing similar issues.

However, I only get this problem (robotic sounding voice from other caller) when I am speaking to someone else who is also using an iphone 5..very strange.

I dont get this problem if I call someone not using an iphone 5

This is my first iphone. I am very disappointed.

Shame on you Apple.

My iphone 5 seems to have a similar problem with people on the other end of a call being choppy and mechanical sounding. So far, though, this is limited to when I use the earplug/mic rather than just holding the phone or using speakerphone.

Before you blame the earphones: (1) I tried the earphones that came with the phone and then other earphones I have used on my blackberry without issue. The results were the same. (2) People on the other end could hear me well, but they were mechanical sounding and choppy to the point of being impossible to understand.

On one call, I tried with the earphones, with another set of earphones, with speakerphone, and then holding it to my ear. It worked fine for the latter two but was terrible with each set of earphones. Same results with our without my thin TPU case. Same result whether I am holding the phone or have it on the table. I am getting 4 bars on LTE throughout.

I was shocked at the difference when I put it on speaker and could hear the other person very well. That suggested to me that there was either a problem with the earphone jack or a software problem. Since everyone seems to hear me fine, though, I thought it was more likely software. I turned off the phone completely and then back on. The problem disappeared for a while. But now it is back.

I have a few more days within which to return this to Verizon. If this isn't solved before then, it has to go back. If anyone else has a good idea, I'm interested.

I should correct something here. It is 4 bars all the time, but in further testing I noticed the "LTE" goes away. I think that is supposed to happen because voice doesn't go over LTE from what I read today. But maybe I am wrong.

Update: I was on the phone to someone not using an iphone and I got robotic sounding voice..So, it appears this problem is occurring across the board

i have the same problems here in germany. incoming and outgoing calls sound good to the other end, but for me everything sounds like a water diving robot. wifi has noting to do with it as it also happens in the car driving on the highway.

Carrier is Deutsche Telekom - their hotline doesnt know anything about the problems and the apple store near frankfurt tells me that there are no known problems. they also told me that it could be because i might have dropped the phone because it has scretches over and over - note that its a black iphone 5, and after a week it looks so bad, compared to that my "old" iphone 4 looks as new.

have ordered a new "old" sim card and will change back to iphone 4 in order not to have try to call my customers six times because i do not hear them.
