Android : Image from android camera with right side up

I'm trying to show to the user image from camera with right side up - no regard to how he holds the phone.

My code is simple:

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
cameraIntent.putExtra("return-data", true);                 
startActivityForResult(cameraIntent, CAMERA_RESULT);

Then I attach returned image to ImageView in onActivityResult.

I know how to rotate the image, but how can I know how user hold the camera when he took a picture?
