At&t Samsung express prime screen material

[Mrbeachballs]

What is the screen material on the at&t samsung express prime? All the phone spec sites say gorilla glass 3 or 4 and other j3 variants have some Dragon glass. It feels like plastic too me and has a lot of resistance and smudges easily. Nor at&t and samsung specify what it is so I am assuming it's plastic or some cheap glass but my guess is plastic.
