Ron hears that Amazon offers apps for free every day. Is that safe or should he just buy them from Google Play? Leo says that Amazon is not only safe, but probably safer than Google Play itself because they vet every app. And it's not like he's getting his apps from "Joe's apps" or anything.
Ron will have to go into the settings and enable the ability to get apps from other stores. That's safe to do as long as he is careful. Amazon is perfectly safe, though.
