Make sure photos are saved with the same orientation they were taken?

For some reason, my camera app saves all photos rotated 90 degrees (pictures only look right when taken with camera on landscape mode) I believe onPictureTaken should rotate photos automatically but I read there is a problem with Samsung devices (I haven't been able to test it on another brand so I don't know if it's the case). This is my code:

   public void onPictureTaken(byte[] data, Camera camera) {
      // Generate file name
      FileOutputStream outStream = null;
      outStream = new FileOutputStream(filePath);
      outStream.write(data);
      outStream.close();

I was thinking it could be fixed by checking the orientation and rotating the byte array but there must be a more straightforward way to do it since handling byte arrays is a pain. How can I make sure photos are saved matching the orientation they were taken?

Try something like this:

int orientation = Exif.getOrientation(data);
Log.d("#", "onPictureTaken().orientation = " + orientation);
if(orientation != 0) {
     Bitmap bmpSrc = BitmapFactory.decodeByteArray(data, 0, data.length);
     Bitmap bmpRotated = CameraUtil.rotate(bmpSrc, orientation);
     bmpSrc.recycle();


       try {

             FileOutputStream localFileOutputStream = new FileOutputStream(filePath);
             bmpRotated.compress(Bitmap.CompressFormat.JPEG, 90,localFileOutputStream);
             localFileOutputStream.flush();
             localFileOutputStream.close();
             bmpRotated.recycle();

           }
        catch (FileNotFoundException e) 
           {
              e.printStackTrace();
           }
        catch (IOException e) 
           {
               e.printStackTrace();
           }

      } else {

          try {

               FileOutputStream localFileOutputStream = new FileOutputStream(filePath);
               localFileOutputStream.write(data);
               localFileOutputStream.flush();
               localFileOutputStream.close();

               } catch (IOException localIOException)
                  {
                                        Log.e("#",localIOException.getMessage());
                  }
   }
