Can't talk to people with it closed

[Anjow]

Lately I've noticed a problem with my Universal. When I answer a call with it closed, I cannot hear the person who is calling. I don't know what could be causing this - has anyone else experienced it? If I answer with it closed...then open it... I can hear them just fine, same for when I answer with it open. I believe they can hear me with it closed, I just can't hear them.

It worked fine closed until around a week ago.

Can anyone think what's wrong?

Sounds like a hardware issue, I suggest u visit your local service point.
