My LG Chocolate Touch will only work if the headphones are plugged in. The speaker does not work. I cannot hear and whoever I call cannot hear me.

1) Reset the phone.
2)Try again, and see what happen.

3) If not work, you must go to repair shop, the speaker will be faulty.

God bless you

Just greak your cell and take a co0l breath and Rest :) :P

I assume you have tried turning the volume up during a call? if so and the volume is all the way up and nothing is coming out, try plugging headphones in to check that there is sound that way. If there is, remove the headphones and that may fix the problem itself as phones can get confused "thinking" there are headphones in when there aren't.

The first solution would be to try to remove all the chocolate from the speaker. This may include opening the phone case and cleaning the speaker directly. Note, this will void any manufacturer's warranty.
Chances are that the speaker is no longer working at all. It has most likely been damage too severely. If you can handle using only the earbuds, than that may be the best solution. This model phone also has bluetooth, so you can use a bluetooth accessory as well. Unfortunately, it appears that your speaker is beyond the point of being saved.

hi, your phone has a speaker...whenever you talk it is this speaker that allows the other person at the other end will hear what you are saying...so when this speaker is faulty, you will not be able to communicate with the other person...all you need do is to change the speaker referred to MOUTH PIECE.

tis is an software error.. try installin ur software again by going to lg service station..

This really annoyed me too, i had the same problem, took me a bit of playing around with it to fix it. Dont take it to teh shop do this.
1. Click on the blue dice at the bottom, and then from the entertainment section go to FM radio.
2. touch listen via

Restart your ipod by holding the home and power button at the same time, this will restart it and should fix it.

Make sure the Volume is turned up. The Side Key(if it has 1) will turn the volume up.

try this
go to setting and tools on ur phone ----> call setting---->TTY Mode---> select TTY+Talk.

hopefully it works.
