detect if front camera in MediaPromise

I am using MediaPromise to get an image from an Android phone's native camera interface.

I am rotating the retrieved image 90 degrees to account for front camera.

The question is: How to detect if the camera used is from the front or back?

If I can detect it is front, I will rotate the image.

I tried a if(height>width)   but regardless of which camera they are all landscape.
