    Just got my phone yesterday.  I know I moved the piece of clear plastic from the back of the phone to the front thinking that I would protect the glass....  it must have been shortly thereafter I noticed I couldn't even hear the phone dialing when I called someone nor could I hear them answer the phone.  I could however hear them if I hit the speaker.  Called my niece who has had an Iphone for sometime and she couldn't make head nor tails of it.  Just for the heck of it I Googled it to see what I'd find -- low and behold I am not the only one having this problem.   Luckily though, I am one of the embarrassed ones who had the plastic on and once removed it's working fine.  I will however be much more aware of the possibility of this problem occuring as a result of a blocked/clogged headphone hole.  I'll also be more aware of where I keep my phone since it must be sensitve to dust or crumbs getting in the exposed holes.  I hope Apple reads these forums because most phones I've had have these holes covered when not in use.  Thank you Mr. Cooper for this very simple fix. : )  Thank you to everyone who offered their experiences and posted to save me a trip to the store.

    Ok, so I just fixed mine. I spilled coffee on my iPhone 4 hours ago, and I just noticed now that I couldn't hear from my receiver at all.  I took a piece of toilet paper, made it really skinny  to fit in the earpiece hole (top left hole). I inserted the toilet paper in the hole until there was no more coffee stain. I didn't think it would work, but when I turned on my phone, it worked perfectly!!! Yay! I have to cancel my Genius Bar appointment now. thank God!

    I have had my iphone 4 for 1.5 years and today when I called someone I could barely hear them when they picked up. The real sign is you wont hear the phone dialing. ok so here is the fix. Just reset the sim card. Use a paper clip or sewing pin and push in the small hole at the side. You have to push a little hard and the little tray will pop out. Then remove the sim card from the tray. The first time I just slid the tray back in and nothing. So remove the card and then just place it back it in the tray and slide back in. I share this in the hopes of saving others time as I wasted a good three hours restoring my phone etc... good luck

    I have had my iPhone 4 for over a year and just started to have this problem! Try blowing into the earphone jack and then plugging and unplugging the earphones just once worked for me!

    maybe you should listen

  • Krodo Level 1 Level 1

    So I'm having the same issue that it seems WAY TO MANY others are having where I make a call shows that the person I'm calling picks up ( bc the clok timer for the call starts) but I hear absolutely  nothing.  I have tried all of the little tricks that others have suggesting and still nothing.  The best part is is that I just recieved my phone back from repair TODAY!! And I've only had my phone for 2 months and this has been going on from the start. 




    I really hope you guys read this and fix this problem a.s.a.p.  This is extremely frustrating to the point where i think I rather just throw my brand new $600 phone off my balcony and go to a blackberry like the rest of the world.  Don't get me wrong I love my iPhone.  I've had every iPhone from the first right up to this 4s that I have now. And before this problem I would have suggested an iPhone to anyone and everyone. But after all this bs with not getting it fixed when I sent it in....not being able to make calls for work ( which I rely on a everyday basis)... Not to mention not having anyone being able to give me a CLEAR reason/solution to this problem, I will never and I repeat never buy another iPhone. 



    So frustrated. So upset.  So disappointed.


    Thanks apple for nothing.

    Although this is an old thread, it's what I found when I had this issue, so I'm posting my resolution after a visit to the Genius Bar. Essentially my earpiece screen (directly above the touchscreen) was dirty. She took a flat, dry toothbrush and swept it horizontally back and forth a couple times and then vertically back and forth a couple times. Fixed the issue. I was skeptical because I would not have though debris could have so suddenly cut off the sound -- would have imagined there would be slow degridation of sound -- but not so. If you're trying this, you might as well clean off your mic screen using the same method.

    Hi. I'm having the same problem. 3 days ago I made a call and I couldn't listen or be listen. So I restored the IOS on the phone. Problem solved for 48h. Today the same problem appeared. Is this a software problem or a hardware problem ? Can anyone help, please ?

  • MandevilleiPhoneUser Level 1 Level 1

    It was a hardware problem with my iPhone 4S. When I brought it to the Apple store they replaced it immediately.

  • David Branco Level 1 Level 1

    Thank you for your response. Tomorrow I will go to my operator but probably they will send me to an Apple store. I'll give feedback then about this issue.

  • clkel Level 1 Level 1

    An update to my post on 2/13/2012: My phone worked for a couple hours after the toothbrush cleaning and then went right back to not working. Went back into the Apple store and they replaced my phone with a refurbished phone. So far so good, so it appears it was a hardware issue.

  • pstromi Level 1 Level 1

    i had the same problem and just fixed it by blowing compressed air into the speaker opening and the plug in spot for the ear phone jack.  hope this works for you. it is very frustrating.  good luck

    Hi everyone. Yesterday I went to the Portuguese operator that sold me the iPhone. They have send it to Apple. Probably an hardware problem as so many of you have said. When I recived the phone back from my Operator I will tell you all what happened.

  • Wasi43 Level 1 Level 1

    Hi I had a similar problem, where my speaker wouldn't work also couldnt hear any calls but only worked when I changed to speaker on, so I thought it might be some kind of fault or apple was trying to make more money off you from date of purchase, so I reset the date to one month back, and magic everything was working perfect, no blowing or cleaning or bashing the phone or taking it back to a repair shop, try it it might work for you too, my problem occurred today so I set date back only one month, try give me ure thoughts
