A few moments ago, Samsung released an update for Kids Mode on its new Samsung Galaxy Tab 4. This involved the addition of new sounds and animations, bringing it much closer to the kid-friendly mode that debuted at the April/April Galaxy S5. Apart from the already mentioned news, however, this update does not bring anything else, for example, the option of creating an account for children, selecting the applications they will be able to use or the contacts they will be able to call is still available.
