Q: No sound only during phone calls??

same issue

min is iPhone 4

iOS 5.0.1

are you sure restore is gona work?

did you try it yourself?

The iPhone's voume switches will control the volume of a call only when a call is active.  Have you tried to adjust the volume during a call?

The volume switch should only affect the incoming sound volume. It should not mute the out going sound level.

I have the same issue, no sound what so ever from speakerphone, earpiece, headphones and the other end can't hear during calls. All 3rd party Apps such as skype work, just not the phone app. It is driving me crazy and i need a solution ASAP, somebody please please help us all!! APPLE HELP!!

same problem. My firmware is ios 5. Everything works fine, such as SKYPE, except typical calling under the carrier. HELP!!! APPLE HELP!!!!

I had all these same problems/symptoms. If, after receiving an incoming call or having someone pick up on an outgoing call, I hit the speakerphone button then I could complete the call with speakerphone. I spent three hours at the Apple store only to be told it was a hardware issue and that I could live with it or buy a new phone. I decided to live with it but it quickly became a pain to always have to use speakerphone with calls. If you have the same problem-I may have an answer. I tried EVERYTHING I found online and nothing worked for me until I found my answer by accident. I was trying to listen to a voice mail someone left when I realized I had the same problem for VM's as I did for calls. I hit the speaker button inside VM (upper right corner) so I could at least hear the VM. One day while listening to a VM this way I got really mad and hit the speaker button 4-5 times in a row as I was very angry! It ended on speaker off but as I went to hit the button again I could hear a little bit out of the earpiece! I quickly hit the sound up button on the side of the phone and turned the sound way up and it was working! It lasted about three calls and then stopped working again. When it stopped during a call I tried hitting the speaker button a few times on the keypad during the call but it didn't work so I finished the call on speaker. As soon as the call was over I went into VM, played an old VM and hit the speaker button there until it started working again. It took about 7 times but did work! This time it lasted over a wekk then I went through the whole process again. This third time has now lasted 2 months and is still working perfectly for me. I know this is long but if it works for anyone else it's worth it! I don't know why the speaker button on calls didn't fix it, only in VM and maybe it will be different for others, but I'm convinced it is some weird software issue and until they solve it, I have this little trick working for me. Good Luck!

So it appears this hasnt had a solid answer yet to resolve the issue.

After the restore process DO NOT RESTORE FROM BACKUP.

Choose the setup as new- Disconnect the device.

Follow Prompts on screen- once back at home page - test make a call - if doesnt work or only works on speaker phone-  you have a Hardware issue and need the device replaced or serviced.

I have same issues a 3GS on 5.1.1 I have sound except on calls then I have to use bluetooth or headset.

I had exactly the same problem on brand new iPhone 4S.  Only 2 weeks old.

In the end i backed up the phone then restored back to original OS using iTunes.  I tested phone and sound problems were resolved.  I then restored the backup and tested again and sound problems still resolved. I think there is something weird going on in the OS that causes this problem.

My solution: I removed my Otterbox cover, and switched on the sound switch on the upper left hand side.  It had been moved to an off position - happens with protective covers.

This just worked for me! I could only hear out of the speaker on a call (when speaker was pressed). I thought I'd give it a this a go to listen to a voicemail, repeatedly press speaker in the top right. At first nothing happened (I must have pressed it about 30 times!). I then started playing with the volume buttons whilst I pressed the speaker button and noticed, when not on speaker, the volume read 'headphones' on the screen. Ah!

Maybe it thought there were headphones plugged in the whole time? I cleaned out the headphone jack with a cotton bud in case there was anything there (moisture, dust etc). Speaker on and off once more and it worked! Bizarre! I hope it stays working

Thanks for the tip, I never would hve tried this otherwise!

Good luck everyone!

I had the same problem, no sound was coming from earpiece, whereas Speakerphone and headphone was working fine. When using volume button, it read "headphones" on the screen. OS or system assumes your headphone is still ON.

I tried all different suggestion which didn't worked. What i tried was "Close all the opened app, and thats it,  and it worked fine. Hope it works for you too.

Good luck.

one of my client has the same issue with his iphone 4 factory unlocked.audio was working in voice memo nd even mic but not during call,even if a call comes the screen show nothing-no sound no calling person identity.wel i tried to restore it to the same version and it worked fine,the solution for this strange problem is either restore to same firmware or upgrade it.its 100%working solution.

tested by me

hope u people find it useful

I have the same problem, so far it has only happend like a coupple of times and everytime my solution has only been to restart ("Slide to power of") the phone.
