The Samsung Galaxy Alpha smartphone has been on the market for a few months now and we have learned a new detail about the device from Corning. Corning has announced that Samsung’s Galaxy Alpha is the first smartphone to use Gorilla Glass 4 to protect the screen from breakage.

Samsung is using 0.4mm thick Gorilla Glass 4 as the discrete touch cover glass in the Galaxy Alpha. Corning says that Gorilla Glass 4 is its most damage-resistant cover glass ever produced. Gorilla Glass 4 is the result of extensive research into why glass breaks in use according to Corning.

Researchers found that 70% of glass failures in the field were the result of sharp contact to the glass. The researchers at Corning developed methods to test devices in the lab using the data learned about real world breakage and created Gorilla Glass 4 to help prevent breakage, while still supporting sleek and thin form factor devices like the Galaxy Alpha.

Corning also notes that Gorilla Glass is now used in over 3 billion devices around the world. In total, 1395 product models use the Corning product.
