I checked All the indicators in dji go 4 were all normal, i upgraded the firmware according the procedure.. I had inactivated the beginner function and activated gestures control in dji go 4..but it still did not work.. The spark still not recognized my face..
Finally i tried to push double click on off button quickly and its work... The spark recognized my face and started to fly.. So the key is the way you push the double click on on off buttton to start the palm control..push it quickly..
