Does the Mi 4i have a Gorilla Glass 3 protection?
No, but this according to Xiaomi, it isn’t less stronger than that. Two reasons, first is that the screen is made by Corning (who makes Gorilla Glass), and second, that it is OGS (one glass solution) where three units, i.e. display, touch panel and the screen protection which is made strong enough to match the rigidness and scratch resistance offered by Gorilla Glass 3. Although they were confident that it can resist some accidental falls, don’t expect us to do that to test the toughness.
