I had the same problem as everybody here. Nokia wanted me to send it in, which is a royal pain, so I decide to have a go at fixing it myself. It worked!

I'm not an electrical engineer or anything remotely qualified, but my diagnosis is that this is a hardware flaw. The speaker in the ear piece makes contact using 2 pins. These pins are at an angle. If pressure is put on the speaker (bottom left in landscape) the pins will be pushed in. When the pressure is released the pins don't return to the original position meaning there is no longer contact. This is fitting to my and other peoples reports that applying pressure returns the sound.

I couldn't take pictures as I didn't have another camera about. However, I made a pretty diagram to help others if they want to do the same. The process doesn't require breaking anything or removing warranty stickers, but it's likely to leave a scratch or two and some worn screw heads.

Disclaimer: It's your own fault if you break your phone. This process most likely voids your warranty if they notice you took your phone apart.

You'll need a phillips screw driver and a flat head to leaver off the front frame. Removing the frame is the most complex part and took some time to figure out.



Good luck
