No Gorilla Glass for Mi5s, unfortunatelly. It is also a big problem to find proper screen protectors (tempered glass TG). I ordered one TG on Amazon and had to return it because it did not fit (Mi5s is a bit curved on the edges). In general I'm very satisfied with my Mi5s but the lack of Gorilla Glass is a real downside. It is unexcusable for Xiaomi to save 5 dollars at this crutial part of the phone.
