Stand 2-3 meters away from your phone. Frame yourself from head to toe, leaving space on all sides. Use a tripod or prop your phone against something stable.
Start facing the camera for the first 1-2 seconds. This gives the system a clear reference before you start moving.

Avoid busy backgrounds with people or moving objects. Plain walls, open spaces, or simple interiors work best. Good contrast between you and the background helps accuracy.
