Iphone 4 no sound!

[Yoyoyo1230]

Hi my iphone 4 is losing the sounds when locking, unlocking, playing apps, music playing and texting. Ive checked the settings and there are all fine.
It comes up with a message saying this accessory is not for this iphone, even if its not connected to anything! Ive always used my genuine apple charger and leads, ive tried a system restore and back up and the problem still persists!

Thanks for your time tom.

Try flipping the mute button up. Also, maybe you should restore it as a new iPhone. It'll will ask you restore as old iPhone (or something like that) or restore as new iPhone. Do the new iPhone option.

My iPhone 4 lost audio too..

Hey my iPhone 4 lost audio after the most recent update I noticed (not sure if that was just a coincidence). Sounds were only audible with earbuds plugged in. Apple was very helpful and sent me out a replacement saying the device must have been faulty.

If you're getting the "This accessory is not made for iPhone…" message and there's nothing connected to it, the iPhone thinks there's something in the dock connector or you have liquid damage. Look at the bottom of the dock, there's a little visible area that should be white. If it's pink or red, you got liquid damage bud. $199 to replace. If it's white, take it in to the Apple Store for a replacement or call AppleCare. But typically, those two symptoms, no audio and "..not made for iPhone.." alert, are a hardware issue.
