    sk1sk1, it could also vary from call to call, depending on how hard the noise reduction algorithm is hitting. On my phone I don't have the drop-out problem with every call -- rather I'd say between 50% and 75% of them.

    Declan,  I'm not suggesting you'll notice the problem on every call - only that I've developed a way of testing that can reliably reproduce the drop-out problem on 100% of test calls following this procedure.  Very useful to test and see if the problem is present or not on a phone.  Here's what you can do: Use apple headphones in a very quiet room, call Hertz at +1 (877) 654-4400, turn the headset volume down to the lowest setting.  Compare what you hear on your test phone to a control (a good landline or an iPhone 4, for example).  What you'll notice is that a good portion of the initial recording is absolutely missing and silent on an iPhone 5, and completely clear on other telephones.  If anyone can find me any iPhone 5 that passes this test, anywhere in the world, at any time, on any carrier, I would like to know about it.

    I think you misunderstood me. I don't feel a need to test my phone because I already know mine has the problem. But what I was suggesting was that some people may not know they have the problem because even affected phones do not exhibit it all the time. They won't need to make excuses for the poor quality if they don't happen encounter the conditions on which experiencing the problem is dependent. In other words, you said that some people aren't complaining because they have low expectations. I was just pointing out that some (not all) may not be complaining because they haven't actually experienced it yet (but they ceratianly will!)

    Is there a way to tell the difference between the versions?  Maybe the factory identifier or software identifier.  It may save the Apple store some time when they search through their stock of the garbage iPhone 5s.

    I've been keeping up on the responses within this forum and just to add to the record, I've tried every resolve the issues with just about everything mentioned in this forum and no success . I have been told several different scenarious from AT&T and Apple where both push shove to each other. I have also been told that the use of MANY Microcells in the area seem to cause an issue with reception. Honestly, I don't believe that because reception is just about the same especially when you have another iPhone 5 and 4S in the same household and those are not experiencing the problem. I have also been told that it's a hardware issue but what are the odds of all 3 that have been previously replaced have the same problem?

     

    If you see my other posts, you will see that I have explored every option to remedy this situation and have not made any progress. I did receive a text message from AT&T that their investigation has been pushed to a completion date of 1-15-13. I guess at that time, I will find out what their conclusion will be. In the meantime, I have actually changed back to the iPhone 4S so I could actually use the service that I am paying for. I'm trying to be optimistic but with all the issues I've had, it hard to maintain that and I have this feeling that when I do hear back from there, the answer is going to stay within the "we don't know" area and both companies are not going to accept accountability for this issue .

     

    When I went into the AT&T store to obtain a new SIM card, they looked at my account and didn't even ask any questions as to why I was swapping them out. They simply provided me with two SIM cards and was advised to call customer care for further assistance. Amazing service ha? If they call me and don't offer any resolution, this will be a done deal with iPhones.

     

    If any one is interested in an iPhone 5 or 4S, send me a message LOL!!!!!

    Checked with my iPhone 5, 6.0.2 OS, quite room, turned volume down to two dots, had three bars signal strength, AT&T network.

     

    Sounded fine. No problem.

    My wife & 4 of her friends all had the audio problems with their iPhone 5. All of them fine, but after they took the factory plastic protector off the screen.

     

    Not a fix for everyone, who seem to have more 'technical' audio issues but I would laugh at people who have been through multiple replacement phones & only because of the plastic film!

    Charles,

     

    That is great and all but the matter is, we shouldn't have to make such adjustments to use the device itself. The volume on my device works just fine, it's the call handling itself. No matter how low or high the volume is, the line distorts and sounds digitized. As of two hours ago, I am using the iPhone 4S which so far has had no issues for call quality and I am using it in the same area that I was using my iPhone 5 in so that tells me this is a device issue itself.

    Jvw,

     

    No, the plastic lining is clearly not the issue here. I am sure most people have already removed the plastic otherwise, I am sure most people would have already taken their devices back.

    My iPhone sounds fine, better than my old 4. I have made no adjustments.

     

    I travel almost every week and the phone works fine all over the U.S. on AT&T. The only problems are droped calls in low signal strength areas.
