Normalized View Port changes on mobile build.

Hello everyone,

We have encountered a problem lately when creating mobile builds we just can't explain and were hoping some poor bloke here has encountered it before...

Whenever we create a build of our game for the iPhone or iPad, the game doesn't seem the fit the entire screen even though when setting the correct aspect ratios (3:2 or 4:3 accordingly) in the engine it seems just fine!

Although we're not sure it's the actual cause, it looks as though the Normalized View Port for the camera has been changed somehow during the build process. It shifts the game to the right on iPhone, leaving a portion of black background on the left of the screen and on the iPad it's centered and minimized to the bottom of the screen - with the same black background on all sides. What's more, it looks like some textures or models that leave the game screen (or enter it) leave a "flickering trail" on this black background when entering or leaving the area of the camera.

We're absolutely stumped and would appreciate any help trying to figure this out! thanks in advance :)
