My speaker on my iPhone 4s stopped working. I can't hear my phone ringing, music, apps or use the speaker when having a call. I can still make and take calls when I see them calling but can't hear the phone ring.

I am having exactly the same problem with my 4S. I did all the tricks, on/of, resetting, and blowing but nothing worked. What else can I do?

Never updated my reply - I had to go to the Apple store and get my speakers replaced! Out of warrenty for only 2 months and it happenened immediatley after an upgrade?? 😠

This is exactly what happened to my phone. I brought my iphone to the Apple store and unfortunately was told that my phone could not be fixed. Some of the things that can cause the iphone speakers to stop working is if there is water, sand, lint, or anything else jammed into the speaker or dock area. Blowing in the dock area only helps if your phone doesn't have water damage. Unfortunately for me, my phone had water damage. I always bring my phone into the bathroom with me when i'm taking a shower. The steam from a hot shower can damage the speakers on your phone so I DO NOT recommend bringng your phone into the bathroom while you are taking a hot shower or else you'll find your speakers not working like I did. I hope this helped in some way.

As mentioned by others, my iPhone 4S speakers suddenly stopped whiule I was listening to a phone call (teleconference so I was on mute). Suddenly no sound yet if I took it off speakerphone, I could hear everything fine via the earpiece. Headphones work as well. Very odd. Sounds to me that Apple knows of this defect. I will find out soon as I am at the Apple store tomorrow.

Will post update here as to result.

UPDATE from Dec. 10, 2013 post-

$59 for new speaker hardware. Waited 30 minutes as it was done in store.

If it was the logic board, it would have been $200. The way to tell that it was the speakers was that you could still adjust sound levels.

Hope this helps someone out there.😎

I had the exact same problem on my iPhone 4S. I was trying to think of anything I'd done to the phone that could have triggered the problem. I remembered that I'd knocked the phone of a table the day before. I wondered if something got knocked loose internally, so I started playing a song (no sound could be heard) and I dropped the phone about two feet several times onto a rug-covered floor. On the third drop the sound started playing but then went back off. A few more drops and the speaker came back on and stayed on.

The plugin headphones and remove quickly helped but, i am on an iphone 6

sorry , give to a apple store
