Headset Button Not Working

Same problem to me today, I've turn off/on the iphone and tried with another iPhone headset and buttons on both headset doesn't work...I also cleaned the female jack...
I will try to do and hard reset?

Another topic here of the same problem here

 

I had the same problem, I got a replacement headset at an O2 store, but it didn't work either (they tested it on a display iPhone and it worked fine).

I was planning to go to my nearest Apple store (miles away), but thought I'd trying cleaning out the jack. I rolled up a cinema ticket, stuck it in and twisted it a few times (there's probably a better way to clean it!) and now the headphones, mic and button all work fine!

 

I had the same problem with my iphone 3G recently: headset mic and button stopped working. Noticed that the headset jack actually did not go in fully - a small gap remained. Figured out it must had been some fluff accumulated from carrying the iphone in the pocket.

It took two attempts and was quite difficult to extract the fluff with a sewing needle. So take care - it can easily happen to anyone.

 

Yes

Just to confirm, this worked for me too!

Had same problem. Button and microphone not working (headset speakers were working). Follwed the above suggestion but used a paper clip. I could not see much fuz in there, but I was amazed at how much ended up coming out. Everything worked great afterwards!

 

Wow!

Guys - thank you so much. I've been putting up with not having a working handsfree/headset buttons for the best part of a year - two different headsets hadn't worked with my 3GS so I'd assumed the function had just broken in my phone. Saw this thread, tried clearing out my phone's earphone socket with a paper clip, and IT STARTED WORKING!

Got to love a free fix. THANK YOU!!!
