I don’t think it is a Gorilla Glass, more like chinese knock off gorilla glass. If it is a gorilla glass, then for what reason Chuwi preinstall a film screen protector, a gorilla glass with oleophobic coating will not require additional film protector.
But I definitely don’t want to do scratch test on my own tablet to see it is a gorilla glass or not. But on my tablet it is definitely a glass since it is harder than my previous iWork 10 Ultimate.
