Gorilla Glass 4 is optimized to survive being dropped on the road or sidewalk

While it's nice to have a smartphone with glass that won't break when jabbed or flexed, what most of us really need is glass that can survive being dropped. Corning's just-announced Gorilla Glass 4 is claimed to excel at just that.

According to Corning, it developed the glass using new drop-test methods that were "based on thousands of hours analyzing cover glass that had broken in the field or laboratory." The glass is manufactured using the company's fusion draw process, which is claimed to maintain thinness, durability and clarity, while improving drop performance.

When dropped face-down onto concrete- and asphalt-like surfaces from a height of one meter (3.3 ft), sheets of Gorilla Glass 4 reportedly survived 80 percent of the time. By contrast, commonly-used soda-lime glass broke on almost every drop.

Do we assume that the parallel screen-to-rough-surface drop scenario is the worst? What about the (much more likely in my opinion - and experience!) phone-at-right-angles-to-floor,-corner-first scenario? MW
pmshah
@Martin Winlow . Yes it indeed is the worst as by Strength of Materials 101 that is the orientation where any material is the weakest. You may have noticed a plate glass being carried by 2 men where only force acting upon the glass is gravity. It is always carried with the glass plane in vertical orientation. So far as "phone-at-right-angles-to-floor,-corner-first scenario" is concerned there will be some part of phone between the pad surface and the glass which will be affected more.
