What's happening is mobs in my worlds from 0.15 are moving super fast. I have got it to work on skeleton horses in one world and chickens in another world. I think it is onky mobs that were soawned before 0.16 because both of those mobs spawned in my world before 0.16. I have a video but i dont know how to share it. Also my device is not Samsung Galaxy Note Pro it is the Samsung Galaxy Tab Pro.
