Camera2 image rotation on certain devices

[Andrec-Dxs]

I created a camera project based on your project. I found that you created a variable to check whether if the width of the bitmap generated for the photo is greater than the height, but you don't use the result for anything.

I came upon an issue related with my device always rotating the photo compared to other devices where the image was on the right orientation. Consider using the following code to fix this issue.

var widthGreaterThanHeight = bitmap.Width > bitmap.Height;

            Matrix matrix = new Matrix();

            if (widthGreaterThanHeight)
                matrix.PostRotate(90);
            else
                matrix.PostRotate(0);

            bitmap = Bitmap.CreateBitmap(bitmap, 0, 0, bitmap.Width, bitmap.Height, matrix, true);
