iPhone 4 has no sound during calls
Recently replaced my iPhone 4 screen. When i tried to make a call the phone went straight to speaker-phone once the call was answered. I could not hear the person on the other end of the line, nor could they hear me. I have tried phoning with headphones bluetooth headset and both earpiece/ speaker-phone but the problem still persists. I tried replacing the earpiece but didn't work.
Skype works great. One thing i noticed is that when i make a call with Skype the proximity sensor works. However when making a phone call the screen stays on no matter what.
I put the old screen on to see if that would make any difference but did not succeed.
In addition, i looked at the logic board and i found that the very top was very so slightly chipped? I am unsure of what difference this would make as no component is damaged.

Try going to settings and then sounds, then turn the volume all the way down with the slide bar after that turn it back up, sounds strange but has worked for me on multiple occassions!!

you have a faulty screen, I had the same problem when i purchased a cheap one on eBay. I could not get any sound during calls and the other person could not hear me either. I put the old cracked screen and everything worked fine. I complained to the seller and got a refund, I brought another one which was a bit more expensive but it worked fine.
its a hit and miss i have found with aftermarket LCD/Digitizer screens some suppliers are cheap but somewhere in the manufacturing process something got screwed up, other times its good.

take a pair of headphones and plug them in to the jack. Make a test call. If you hear audio and can hear the caller then it is the earpiece speaker. Got to ebay and buy a kit with the part, and tools. SHouldnt cost more than about 4$ us. come back to this site and you will find a manual on how to replace the part. pretty easy, took about 30 min

Hey Will thanks for the response, i have already tried every type of connection for phoning including a Bluetooth connection in a car and it still has the same issues

Change the dock connector mic assembly. The apps all work off of the top noise cancelling mic and the calls work off the bottom mic on dock connector. Phone may be stuck in headphone mode.

hi guys i have the same problem but the funny things is when i used skype or viber or any apps they work fine bur when i try to make call from my sim card i couldtn hear anything please help please
This answer was originally to another question.
Yes this was the case for me, it is because there is two different microphones in the iPhone 4. One just for calls that has noise cancellation capabilities and the other for voice memos and other apps! Still not found a solution, i believe it is because my motherboard was slightly chipped at the top
