Air sdk (23, 24) CameraRoll read bytes from image. Problem size.

I've got problem with readBytes image from cameraRoll (ios device, android didn't check). The size of the image is too big. The same image in air sdk 23, sdk 24 has 16MB but in air sdk 22 is 1,8MB (this is correct).

private function connectCamera():void
  {
  if( CameraRoll.supportsBrowseForImage )
  {
  _cameraRoll.addEventListener( MediaEvent.SELECT, imageSelected );
  _cameraRoll.browseForImage();
  }
  else
  {
  trace( "Image browsing is not supported on this device.");
  } 
  }
protected function imageSelected(event:MediaEvent):void
  {
  var imagePromise:MediaPromise = event.data;
  dataSource = imagePromise.open();
  if( imagePromise.isAsync )
  {
  trace( "Asynchronous media promise." );
  var eventSource:IEventDispatcher = dataSource as IEventDispatcher;            
  eventSource.addEventListener( Event.COMPLETE, onMediaLoaded );         
  }
  else
  {
  trace( "Synchronous media promise." );
  readMediaData();
  }
  }
private function onMediaLoaded( event:Event 😞void
  {
  trace("Media load complete");
  readMediaData();
  }
  private function readMediaData():void
  {
  var imageBytes:ByteArray = new ByteArray();
  dataSource.readBytes( imageBytes );
  tempDir = File.createTempDirectory();
  var now:Date = new Date();
  var filename:String = "IMG" + now.fullYear + now.month + now.day + now.hours + now.minutes + now.seconds + ".jpg";
  var temp:File = tempDir.resolvePath( filename );
  var stream:FileStream = new FileStream();
  stream.open( temp, FileMode.WRITE );
  stream.writeBytes( imageBytes );
  stream.close();
  trace(imageBytes.length, imageBytes.bytesAvailable);
  }
