    I'm in Nepal and there's no chance I would get replacement here. I ordered my 4S 16GB from one of relatives coming from UK. I've been having this OCNA problem since a month now. I recently updated IOS to 5.1 and it did work for a day. Then again same problem.  However 5.1 did fix the problem of incoming SMS with + country prefix code. I'm little relief that now I know who is texting me, otherwise I had to verify the number after the country prefix code to identify the sender.


    On the OCNA, my experience is that, the problem re-appeared after I had toggled with speaker. I would rather not switch to speaker mode if my phone again switch backs to normal.

    finally got my 4S 64GB replaced after it not only had the outgoing-call-issue (which i posted here about 900 posts earlier) but also lost its WLAN-function after 2 month of usage, what a piece of crap;

    before that, the phone-support made me completely restore and setup the newest ios5, but that didn´t work a bit.

    it´s my first replacement and it´s working fine - at the moment...


    cheers from vienna/austria

    I have the same issue once in every 10-20 calls. The only solution that works for my iphone4s is to reboot. Ive tryed with and without different types of headsetts.

    Original I thought the could be fixed by software reload. This is not true. My phone got crazy last night. Tried 5 outgoing calls but the first 4 had ocna issue. Finally, I have got it replaced tonight and so far so good.

    Follow up to my post at:



    I am almost 3 month into the replacement phone (black box, no accessories) and the phone works fine, no sign of the previous issues. It is not perfect though, every single outgoing call will take about 2-3 seconds until the person can hear me and this is very repeatable.


    Relative to all the comments here about these issues being hardware and/or software related, the situation is not like black and white. The functionality of these phones is based on few ICs (integrated circuits). Most of these ICs are programmable these days but some features more so than others. For example, you could have a switch chip. You could program it in the firmware to turn on or off and you could put a delay in to take longer between toggles but you can't go below it's hardware switching time and if you needed that you would be out of luck.


    My point in the example above is that there are things that could be adjusted from firmware programming but not everything. The only way to tell and not guess is by knowing the schematic of the phone, the programmability of the ICs and the software. Everything else is meaningless discussions.


    I believe with a high degree of confidence that Apple is well aware of the issues posted on their websites but due to potential implications for their business will take the time to get to the bottom of this and fix it if they can or come up with a replacement strategy if this proves to be a major quality flop.


    Now speaking guessing job, I believe that since the flaw is recurring in recent batches, well after these issues surfaced 2 month ago, probably Apple believes that they can fix this in the software at least to a certain degree. I am well aware of Apple's quality levels and they would not continue manufacturing devices using faulty hardware components. They would go after the specific manufacturer and make it pay dearly.


    It's hard for people from countries where the retailers have their way selling malfunctioning stuff but try to hang in there, if you have no choice, for the next IOS release. I am confident things will get better on the Apple side for this product.

    today i went  with my phone to service..


    while i was waiting another costumer was picking up his 16 GB 4S Iphone (same model as mine).. so i asked him what was the problem, and surprise.. the same OCNA problem.. in every detail.


    i left my phone there, in maximum 2 weeks i will get it back probably with the software restored and with the same problem .. hopefully they will give me a new one asap.

  • gabelu Level 1 Level 1

    The other customer has recieved a new one?

  • bgd83 Level 1 Level 1

    No, unfortunately for him no.. maybe if the problem persits. did you get any answer from them ?

  • wylievc Level 1 Level 1

    Hi, I would just like to tack on my experience to this thread. I'm sure most of what I add will not be new information.


    As I place a call either: my phone outputs a scratchy crackling noise and then connects and continues on to the ring back and eventually an answer (or answering machine); OR, randomly up to about half or more of the calls I make, the phone will begin calling, showing the timer and all, but output absolutely no audio. The other party in which I am calling still receives this call and can answer it and even hear what I am doing/saying, although I cannot hear them (nor myself echoing). I can occasionally resolve this by toggling the sound/no sound tab on the side back and forth or by toggling the speakerphone setting on screen, but this also does not work every time or even that often.


    I purchased my iPhone relatively recently (December 26, 2011) and have not noticed any other major bugs, although I feel that when running intensive apps it may be getting hotter when comparing to other iPhones (but this is most likely not correlated with the OCNA issue).


    I contacted apple and they instructed me to reset my settings and then restore factory default. This did not resolve the issue as the first call I placed when the phone was restored had the same problem. I'm sure I can pursue this enough to get a replacement phone.


    I don't know if this is a hardware or software issue, both, or just a bug that will be fixed. Are there any temporary solutions, or perhaps apps, that can help get by this until apple finds a solution?


    Thank you.

    For all of you that experience this issue with 4S, try this out:


    Backup all your data in itunes or whatever other place you like, reset the iphone as a new device without

    using any of your backup files. When you do this you will get the latest IOS 5.0.1 (9A406). If you dont reset as a

    new device you will get IOS 5.0.1 (9A405).


    Doing this made my phone having alot better battery capacity & fixed the outgoing call issue (temporary for the audio issue).


    When the audio issue return here is what was working for me: Switch on the 3G in settings (if you not already have it switched on). This seems to losen up the issue.


    Let me know how this works for you.



  • HysteriaPL Level 1 Level 1

    If this is a software issue then why change the phone for another model with the same software solves the problem? This means that in future firmware upgrade will not do anything because the problem must be hardware. Apple certainly seems aware of this and had to change something at the hardware level. So why sell models with a factory defect and then brazenly exchange them for fixed-used?!

    Would you advise hot to get back all iCloud data then? And if it's possible to get back any apps installed like they are or the way is only to download it one-by-one?


    Actually, after the last repolacment I got perfect iPhone - no OCNA issue at all, but the firmware still 9A405.

  • jaxo Level 1 Level 1

    my first call out fails almost regulary, I need to dial out same number two three times before I can hear people on the other end.

    very frustrating and very bad for business...

    I see this conversation started back in october and still no fix from apple? has apple gone microsoft way???

  • borut from celje Level 1 Level 1

    I got an advice from my friend, so i said i'll give it a try.


    I went to the VOICE MEMO, recorded 5 seconds of my voice, listened to it and then restarted the phone. I have to say that form the last saturday i haven't had any no audio on outgoing calls problem. Today is thursday so we will see if i can make it one week without the problem


    It is stupid tho, because i don't have the trust anymore in the phone, even if the problem is/will be fixed.

  • EdHart Level 1 Level 1

    It's the same story here in The Netherlands: No sound on outgoing calls, they can hear me, I don't hear them (5 out of 10 calls).

    Switching the speaker on/off fixes it for this call.

    I'm on  IOS 5.0.1 (9A406). Provider KPN.
