iPhone 4S - Outgoing call no audio

Same problem here. I have two 16gb 4S's. One has no prob but the other has the exact problem listed here. I am on the latest 5.0.1. Apple needs to get their act together.

Is it possible to upgrade modem firmware to the one in 5.1 beta 3, yet keep the rest as iOS 5.0.1.?Maybe by upgrading just the modem firmware will solve calls problems yet keeping the benefits of the 5.0.1. Maybe it can be done with custom firmware.

Further, I upgraded to 5.1 b3. Every thing wa fine. When going back to 5.0.1 things were good till I installed Buber and made the first cover call. Then the problem stays. Could this have to something with the problem?

This fixed my problem. Couldn't hear through the phone earpiece. When I made phone calls, I could only hear the caller or hear the phone ringing by turning on my speakerphone or using my bluetooth. Resetting and restoring did not fix this problem. Had used an earpiece plugged into the phone jack earlier to listen to music.

IOS 5.1 Beta 3 has a bug about Keyboad, when you go back to home screen from Spotlight search the keyboard dos not disapear, and it is still on the screen

but the OCNA has been fixed.

I've been using beta3 for several weeks & have not faced with the problem you claimed. perhaps you should do a clean re-install.. OR you might have downloaded & installed a corrupted firmware.

I Just installed the IOS 5.1 Beta 3, after installation, i faced the keyboard problem, but when i restared the phone (completly poweoff and on ) the problem solved, but after 8-9 days i happened again, i think in the specific situation ( may be in some state of software, IOS, or memory ) this problem has been occured, i cant figure out how can i simualted it again but it is exist, some other people have this problem too, it is not uniqe.

Today after 6 days I got a brand new iPhone. Service told me that this is a hardware problem, and therefore exchange a new one. New iPhone works perfectly. Greetings from Poland.

Same problem. Just got my iPhone last night through Telus in Canada.

No handset sound on outgoing calls. It's not random or anything like that. Every call I make has this problem. Quickly figured out the speakerphone workaround, but I'm not impressed.

Talked to Telus tech support and they said I'd have to bring it into the store, that I only get 3 total repairs, and that they very likely would not replace the phone.

So, screw that. Going to deal with Apple directly and get a replacement, just in case.

Same problem. SIM Card of TIM Brazil

Since it's obvious there are tens of thousands of people facing the same problem, perhaps we should start writing serial numbers (or part of it) of our iPhones 4S? I mean, there must be some common denominator between our phones, which would help quickly identify the ones facing OCNA.

Once we know the easy way to quickly identify phone with the problems then all matching the criteria could go for replacement?

I mean, this should have been done by Apple already, but since we're not getting appropriate support nor attention then I guess it's time (after 4 months) to start taking doing something serious about this.

Is someone following this thread able to identify few phones facing the same problem? Is there anything that is common between them?

For now we know:

1. iPhone 4s ONLY

2. iOS 5.0.1 ONLY

3. 16GB/32GB/64GB ALL affected

4. black/white ALL affected

5. operator RANDOM/ALL

6. country RANDOM/ALL

BTW, easy way to reproduce the problem on my phone. Turn off bluetooth, turn on bluetooth, try to make a call -> OCNA problem replicable 100% on my phone

Has anyone found any patterns apart from the above mentioned 6?

Thanks,

M

Thanks Kinst, this is really excellent info ... much appreciated.

So here is current/updated list symptoms:

Symptoms v0.02

==

0. Original Apple dialer ONLY (can someone also confirm this)

1. iPhone 4s AND iPhone 4 with iOS 5.0.1

2. iOS 5.0.1 mostly, but there are some reports for 5.0 and 5.1b3

3. 16GB/32GB/64GB ALL affected

4. black/white ALL affected

5. operator RANDOM/ALL

6. country RANDOM/ALL

===

Repro Steps:

===

Disable/Enable bluetooth, try to make a call.

Workaround:

===

Second call/ speaker on-off MAY help (this doesn't work always)

Disabling Siri and Bluetooth will help to face the symptoms less frequently

Can we make a poll on this Forum? This would help get to the common criteria much faster?

Sorry, it's me again. I think, you started a useless job which will die soon without support of others. Ant it's useles because it won't help even single individual. But...

=== not SOME reports of 5.0. All iPhones now goes with 5.0.1 but at november 2011 and before, who got 5.0 iPhones faces the same. Me persanally got 2 iPhones with 5.0 and OCNA which was continue at 5.0.1

=== Works ALWAYS, if it doesn't work, this mean one have not a classical OCNA but mixed with some other bug.

Disabling Siri and Bluetooth will help to face the symptoms less frequently
=== Who care about "less frequently"? Only MISSING matter. I never had SIRI or BT on but gog OCNA on my first 2 iPhones.

I have the OCNA issue too with an iPhone 4S 64GB white. The iPhone was bought in UK. From the serial number it was made in China, Chengdu, Foxxcon, in the 45 week (November) of the 2011.

My family have another two iPhone 4S too, but these aren't affected by OCNA.

From the serial numbers, one in black with 32GB was made in China, Chengdu, Foxxcon in the 48 week (december) of 2011, the other one in white with 64GB was made in China, Chengdu, Foxxcon, in the 42 week (October) of the 2011.

I live in Italy and I use Vodafone.it as carrier. I tried to restore the iPhone, but it doesn't work. Bluetooth and SIRI are disable. Only if I active speaker on-off I can make ALL calls.

I'll try to use IOS 5.1 b3 to see if it work for me.
