What to do when my iphone (6+) camera stops working?

Iphone 6 main camera (back) only gives me black screen/no picture. Area surrounding the camera lens gets hot while the blackscreen is showing. I get the warning about overheated blitz almost instantly even though its not on. I have tried resetting the whole OS. What do i do next? *purchased 25.10.14
