Freddy works much differently then in FNAF 1. In this game, she has a timer. When that timer hits zero, if you aren't watching her, she will move. She will move a total of 5 times. when she has moved to cam 6, this is her last phase. When she is in this state, the next time she moves, you die. Make sure to close the door after awhile of her being there (im not sure of her exact time it takes for her to move, I believe someone on youtube has made a video on this). If you hear her laugh and aren't dead, she has most likely moved back to cam 3.
