The Samsung Galaxy S4 is equipped with a Corning Gorilla Glass 3 display which is arguably one of the strongest displays currently on the market. One site recently decided to run it through a gamut of scratch tests to see how well it holds up. After being scratched with various knifes, beat with pennies and rubbed with a key, the device’s screen still looks remarkably scratch free.
That means you might not need to worry about buying an extra screen protector for the Galaxy S4 when it launches in the U.S. in the coming weeks. Check out the video above to see how well it held up.
