iPhone 4 no sound from loudspeakers (Headset,under calls works)

Hello, as topic which describes it pretty well. I dont have any sound from incoming calls but can here it well if i answer. And the headset on it works aswell. So the problem is the loudspeaker that doesnt work, changed the speaker and still the same problem.

Doesnt seem like the sound is stuck to headphone-mode since it works when i talk during calls. It's only the loudspeaker on it thats faulty.

Read from a couple of others that it worked when they blew some air and cleaned the dock connector with a needle or something it worked again. I tried them both, doesnt seem to be any dirt left and have no clue how to continue from here.

So, what can I do or proceed? (not water damaged iphone)

Edit:

So all know, i fixed the problem. Was some kind of tape or looked like glue over the 2 metal plates under the speaker where it connects. Scraped it off and worked like a charm!

Check that when you replaced the speaker you replaced everythig properly. The mic is on the dock connector so the speaker wont affect that. Try play music through it without headphones, if no sopund maybe a faulty speaker. Also have a look at the 4 bits of metal protuding on the speaker they must sit behind the metal frame not on top of it

Get a New Charger Charging Dock Port Connector. I had the same problem as you, and when i bought a new Port Connector, it worked just fine and you can hear everything. Hope this helps
