Iphone 5c sounds inop after iOS 7.0.6. update

Hi FAM_Padilla,

Thanks for visiting Apple Support Communities.

I recommend these steps if callers can be heard with speakerphone but not the receiver:

iPhone: Receiver and call audio quality issues

1. Increase the volume during the call.
   
2. Make sure nothing is blocking the receiver. If you're using a protective case or display film, remove it and try again.
   
3. Make sure nothing is plugged into the headphone jack or the dock connector.
   
4. Check the receiver opening to see if it is clogged with debris. If necessary, clean it with a clean, small, dry, soft-bristled brush.
   
5. Try another location with better signal. If the audio issue happens only when on a call, it could be due to the location.
   
6. If the iPhone is paired with a Bluetooth headset or a car kit, try turning off Bluetooth on your device. Learn more about troubleshooting Bluetooth connections.
   
7. Restart the iPhone.
   
8. Make sure your device is up to date.

Since you mentioned that the iPhone is already up to date, I recommend backing up and restoring the phone at this point, using the steps in these articles:

iTunes: Restoring iOS software

If the issue is not resolved after restoring the iPhone software, contact Apple Support.

I am having exactly the same problem on my iPhone 5, also only since the 7.0.6 update. Before then absolutely no problems.

I find that I get intermittent sound from the call speaker when I listen to voicemails but absolutelt fine when I turn the loud speaker on. Nothing at all from live calls but again fine if I go to speaker mode.

It looks to be related to the 7.0.6 update as I had zero issues before then. My service operator (O2 in the UK) is reporting no issues in my area, an area I live and work in and have had no previous issues.
