Samsung launches Marshmallow parental controls app for Android devices
Aside from that, Samsung Marshmallow allows parents to use it to talk about smartphone usage habits with their children. On the other hand, children can learn how to use a smartphone by making their own usage plans, achieving goals, and getting rewarded.
However, I do believe that Samsung Marshmallow is a bit unrealistic since it allows children to make their own rules. For example, a child can set daily smartphone usage time limits, but who's going to do that?
On a more positive note, a child can earn Marshmallow points when he uses his smartphone as he should and loses points when he does note. When enough Marshmallow points are gained, a child can ask the parent for a gift card to use in the gift shops (Best Buy, Dunkin Donuts, Amazon, Google Play).
Samsung Marshmallow is exclusively available for Samsung Galaxy devices and is supported on many smartphones including the Galaxy S8, S8+, S7, S7 edge, Galaxy Note 4, Note 5, Galaxy A5, A7, A8, J3, and others.
