No sound from speaker

Very simple easy fix...grab a blow dryer and turn it on low then aim it at the headphone jack about 6 inches away from the phone and the icon should go away within 10-15 seconds. Make a test call and you should have your sound back.

i had the same issue, i replaced the charge port piece and works like a charm now

To make the sound come back to speaker you just have to take the battery out and put ot back in it worked on me.

It could be you somehow damaged the headphone port when you plugged it into external amplifier. Contact your local LG service to fix this problem (if Factory Reset doesn't help, it is a good idea to contact local service representative).
