Antwoord op "Ear speaker on iPhone 4 suddenly very low, near mute."Yes! Result. Ive done this before with a pair of in ear buds, sucking the metal mesh seems to work if clogged up. The other day i spilled cappucino all over my iphone4s, not long after i had cleaned up the phone, my earpeice vol became very low. This time i used an earbud soaked in saliva pressing the fluid into the mesh then sucked it out quite strongly a few times and it really worked well, i can imagine the sticky coffee mix was glueing the speaker diaphram up.... I could actually taste the coffee coming out as i sucked!
