AShum88, I had the exact problem that you are having, including the screen shots being different (wrong). I have a HTC One X. The problem started immediatelty after I had the battery replaced. I took it back to the local guy who replaced the battery. He took it apart and found a "loose connector". He made a good connection, and now I have the camera both ways, and the menu on the upper left (3 vertical dots) now shows Camera options as either Front or Main correctly (did not show that before). The loose connector must have made the software not recognize two cameras, and adjusted the screen accordingly.
So, did you, by chance, have your phone worked on before your problem started? If not, maybe your camera simply went out, and the software is not recognizing it. I am not a techie, but hope this helps. I found your post when my front camera went out too. Good luck.
