I've done it but still not working.
I'm using my iPhone for now because my RC is under reparation.

At low heights, GPS may not be available. Therefore you get the unstable flight condition.

If you are in a place with low light hovering up from grasses or leafs or a glossy terrain  the ac will be unstable .Also check if the down sensors are clean .Also  check if any metals are close to your ac 1.5 meter close may cause this effects  ... Finaly check your props for dents ot damage put them off the ac to see is they have any damage to theese litle foots they have to lock in motors

This was good info!  Just a kudo for the suggestion!
