IP6 FrontCamera out of alignment

Hi folks,

I started to try Apple some years ago with the IPhone5s. Since the 5s really convinced me of the Apple-Quality I decided to get a new IP6 with a new contract. Now, 5 months after the purchase I am really unhappy with my new IPhone6. Wiggling bock-button for example.

But what disturbes me the most is the fact that the front-camera is now shifted and the dust-filter is visible. I bought the IPhone in order to receive the best quality on the market. Like it was promised by Apple in every Apple-Ad. But now I feel uncomfortable with my new device. As I plan to rebuy my Iphone after 2 years of usage I doubt I can get as much as I should get, because of the frontcamera alignment and the overall lock-button problems.

So what is apple going to suggest me to do?
