Q: No sound only during phone calls??

I have an Iphone 4 that automatically puts it on speaker during a call but no sound the headset works just fine while in voxer or anywhere else it was working fine untill i updated to ios 7.0.3 someone please help!!!

I went nuts over this, I tried several things and was very frustrated. Finally I cleaned out the dust and junk from my charging port on the phone and it worked. Good luck!

I had the same problem... wasnt able to listen to others during calls... I wasnt even able to listen to ring while i was dialing any number. however, on speaker it was working fine... then i saw this video on youtube...http://www.youtube.com/watch?v=MRSDaNcEgPw

it worked magic for me... try if it helps u too...

Just put some tape over the background suppression mic (on top of phone next to the audio jack, small pin hole) .

That lets a faulty mic think that there is no background noise and so it will work fine. Did it on mine, with tape phone's ok, no tape phone cuts my voice off during calls.

I'm having the exact same problem!! Only I have the updated iOS 7.0.4.... It's been going on for about 4 days now and it's getting worse ! I've tried everything !

Im having exact same thing.   not a mic or speaker issue because face time audo and video work fine , as does skype calling.

and im 4 months out of warranty now.     Argh!!!!!

does anyone have a valid fix for this?

My iPhone 4 had no sound or mic during phone calls, but facetime/skype/voice recorder/... all worked fine.

Tried restore with and without backup, updated to 7.1.1 which was just released, then I tried some of the cardboard placements and adjusting a screw near the camera, but nothing fixed it.

I have however managed to resolve my problem, so I thought I'd share it here.

I found this video which helped me:

Taking out the logic board itself is explained here:

I cut an approximately 3x3 mm square from a credit card and plcaed on top of the chip, after reassembling everything I could call again after a week of not being able to.

I was apprehensive about it at first, but the only tricky bit was getting the shield off the chips and that turned out to be not too hard. Some of the screws are super tiny though, so make sure you keep track of all of them!

Hi,

i had exactly the same problem on Iphone 4S, IOS 7. This solution is worked for me, maybe this will be useful for somebody:

Go to:

Settings > General > Restore > Restore network settings

After i selected this, it is working again.

REmoving and re-inserting the SIM WORKED FOR ME TOO

facing same problem in 4s everything working fine bt no sounds during call wat can i do plzzz somebody help

This fixed the problem with my iPhone 5S running version 8.3   I did have to power off and on to get it to take affect.

I had the same problem with iPhone 5c iOS 8.3. This was my friends phone. There was no dial tone when I dialed a number. I could not hear anything while on call and the person that I was calling couldn't hear me.  The speaker icon was grayed out. I couldn't press it when on call. The sound was working through the speaker when playing music. When I plugged in headphones I couldn't hear anything the sound was playing through the speaker even when the headphones were plugged in. A lot of strange stuff. The only thing that fixed this problem is when I put the iPhone in the recovery mode and restored the iOS. The phone is working ok so far.

PROBLEM SOLVED (SORRY FOR MY ENGLISH, I USED GOOGLE TRANSLATE)

4 months ago , I bought an iPhone 4 ios 7.1.2 16GB priced at 60 euros , I knew not hear the loudspeaker and the microphone goes in calls , but otherwise perfectly functional applications ! We looked on the internet and stuff like methods , but did not work , I tried to downgrade to iOS 7.1.2 software to 6.1.3 did not work, until I found a video which I said that 's stupid , but not I had that try , and I said I had nothing to lose. I would put the following link : https://www.youtube.com/watch?v=IGTu-_f2XYk
but before fitting the plastic piece I used a hair dryer to heat the chip respectively , we have installed heated plastic, after which we mounted back in the phone card !, I did not expect any work by Nohow but it functioned successfully!

Same problem here on iPhone 4.

It started acting this way after falling to the floor. After various attempts at reset/hard reste etc i smacked the phone repeatedly against my thigh. After that it worked again, so thats a strong bet on hardware-issue i guess.

Not a lasting fix probably, but it allways feels great when something works again after a good wacking.

They should have this every troubleshooting manual.
