iPod front camera shift, help?

Hello, my ipod touch 4th generation's front camera (or a circle in front of it? i don't think it's the actual camera) is shifting downwards. I've only owned this iPod for about 6 months, as my old one was stolen then. Is this going to be covered by Apple?
I don't want to pay for a phone call for them to tell me that they can't do anything. This simply has to be a factory error, I couldn't have done anything to cause this.
Thanks.
