Use this method to get the Orientation

public static int getExifOrientation(String filepath) {// YOUR MEDIA PATH AS STRING
        int degree = 0;
        ExifInterface exif = null;
        try {
            exif = new ExifInterface(filepath);
        } catch (IOException ex) {
            ex.printStackTrace();
        }
        if (exif != null) {
            int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, -1);
            if (orientation != -1) {
                switch (orientation) {
                case ExifInterface.ORIENTATION_ROTATE_90:
                    degree = 90;
                    break;
                case ExifInterface.ORIENTATION_ROTATE_180:
                    degree = 180;
                    break;
                case ExifInterface.ORIENTATION_ROTATE_270:
                    degree = 270;
                    break;
                }

            }
        }
        return degree;
    }
