Sound issues - only headphones or speaker working

Ummm, this is honestly not meant as a stupid answer/question, but have you attempted to turn the global volume up? (when NO sounds are playing, hit the volume up button, or change it in the settings)

same problem here...CNET suggested plugging/replugging your headset a number of times as a temporary cure but it didn't work for me. I did a full restore without any success. Just started. Have to use the speaker or headphones to make a call...very annoying.

I've only had my phone for 3 days and i just started having the same problem. I tried plugging the headphones in and out, rebooting, changing the ringer volume but still keeps saying headphones are plugged in.

Heading to a store tomorrow.

Hi here Finland,
I have same problem what is first post with my iPhone 4. It's only one day old. 😟

I try plug/unplug headphones but that not help anything. Then i try restoring and dfu mode but those either help nothing. Today i will go to speak Apple Services.

Does anyone know is this hardware or software problem? I am using 4.1 iOS, is there something bug or else?

Perusmuro,

I don't think it is a software issue, most headphone jacks take care of the transfer between speaker and headphones thru mechanical switching.

I really am starting to become gun shy of this forum. It seem like every time I browse it someone finds a new Major problem and as soon as it is mentioned a dozen people chime in with "Yup me too".

This sound like a low quality headphone jack problem and something that will require a phone exchange.

It is just amazing how one high end phone can have so many serious problems and not a single comment from Apple about any of them except for the antenna issue and there reply to that was it doesn't really exist and if it does it is OK because all smart phone have this problem that doesn't exist.

Maybe just because it is late and I am tired but it appears the iP4 has more problems than it has components. Before I get all the folks jumping me about theirs works fine, so does mine but I'll be damned if I am going to plug a headset in to find out if I can break mine - I would just as soon not know. Ignorance is bliss or something like that.

But this is so funny. When i got my iPhone 4. I try facetime with headphones and that's works. I try too facetime without headphones that works fine. I got many calls yesterday and then phone works fine i can heard others but when i left my work and got some calls then i notices that i can't heard anything.

It's got broken when i touch that. Nice.
