Front facing camera is blue, all the time?

Hi there,

Bought a brand new iPhone 4S and only had it 2 days.

Been playing around with it and went to try out the front facing camera and everything has a blue tint to it.

I've already trawled the internet and found no problems that match mine, only ones of a common "blue tint" fault which is not the same as I am experiencing.

I have tried covering the camera with my finger and it doesn't go black, just a grainy blue / purple.

Seems to be minly the blacks that are coming out blue?

Rear camera is fine and not having any any problems.

Front camera problem in both the stock camera app and also tried it in Instagram.

Included the photos to help try and diagnose the problem.

Thanks in advance.
