Best practice is to power off ASAP after landing. Make sure you're using left stick full back for 3 seconds to do that rather than a CSC as the CSC is more likely to cause an unintentional flip over.
Most experienced pilots here recommend learning properly to hand catch and stop the motors while holding the Phantom by the leg stationary in the air. To do that safely, make sure you approach the Phantom rather than flying it to you. Have it hover slightly higher than your head (to keep the blades above you), and gently grasp one of the legs holding the Phantom still while pulling back on the left stick with the other hand for 3 seconds until the motors stop.
Hope that helps!
