Had a problem on my iPhone 4 since last night my phone rings but when I answer there is no sound.

I can't hear anyone on other end.But they can hear me. When

Trying to call out there is no sound just silent. The sound works perfectly on loudspeaker and

On headphones. The mic and speakers seem fine.

Do you need to still be in warranty to use the genius bar?

I don't have a clue what to do?

Anyone else got the same thing?

Any help appreciated?

    You do not need to be in warranty to visit the genius bar, depending on how far out of warranty it is they may help you out, try backing up your iPhone and doing a restore then resync, worth a shot. But if it software related if you re sync all you will do is put the same glitch back on your iPhone

    I'm curious so bear with me.


    1. Are you on just a 4 or are you on a 4s?


    2. Did you update to 5.1?


    3. If so, did this happen prior to you updating to 5.1?


    I ask  ecause a lot of people with the iPhone 4s are reporting what sounds like the same problem you're having. I am on an iPhone 4s and have this issue, but my mother is on an iPhone ; and has the same issue, but to a lesser degree (happens less often).


    A lot o people believe it is a hardware issue, but I personally am not so sure. My mom can't remember having this issue prior to me updating her phone and my phone cam with this version of iOS on it.


    Anyway, I look forward to your answers.

    Sorry for all the typos. Posting from my bed on my phone. I only just woke up.

    I've tried the restore and I've tried resetting my network stuff and so far nothing.


    It just always comes back. Someone on the 'big post' has reportedly switched to the 5.1 b2 software (dev software) and found success in that they no longer have the issue after 70 phone calls. Hopefully they release 5.1 (I meant 5.0.1 earlier - sorry for that typo, again) soon with all of this crap fixed.


    I figure taking it back to the Genius Bar, for me as a 4s user, is running the gambit. There are four very annoying issues with these phones right now and I'd take this over all the rest. (Audio problems [I have], yellow screen, static issues and bad battery life).

    Adam, I'm curious. Did you try at all to hit "speaker" twice (the iphone 4s workaround) and if so, does it resume audio as normal?

  • AliceKaye Level 1 Level 1 (0 points)

    Sure thing!



    This is the huge iPhone 4s discussion.


    Basically when you make a call that has no audio, all you have to do is turn on the speaker. If you don't wish to speak on speaker mode just turn it back off and you should have full, regular audio.

    IVE FOUND THE SOLUTION!! This has been a problem for me for a while now!!


    Anyhow.... Alot of replies on here said the make sure the headphone duct was clear of any dust or obstacles; HOWEVER, i found that aswell as that, i needed to clear the charger duct. Im not sure if there was dust in there too, but i found that blowing quite hard into the charger duct solved my problem. I tried many ways i saw on here, but found that the sound kept flicking on an off everytime i attached my charger. I blew into the duct to clear it and... WOL LAHHHH!!! Problem solved! I did also update my phone which apparently fixes any bugs, so hopefully i will not have this problem again!!


    HOPE THIS HELPS GUYS! Let me kno :0)

    AMAZING !!!


    100% true - it is all about the charger dock. I have also clear mine and now i have my outgoing call audio back.

    Thank you very much !!!

    I have blown strongly and clear it with a piece of paper or something smoother - not metal!
