Thank you for that information.
This a failed Microphone element. It a tiny part, but it needs to be replaced by any local LG phone shop.
It takes about 20 minute or less and it will be as good as new ;-)
The cost is less that $20.00 for the part.
But you can get a new one for less that that on E-bay as well, below is the link for that if you want to check into that?
If you go that route, all you need to do is use your sim card in that phone and it will work right then.
Here is the link its a long one lol:
