If you thought that the Gorilla Glass 3 on your smartphones is the most rugged screen protector yet, then you would be happy to know that Corning has made official the successor to Gorilla Glass 3.

Called the Gorilla Glass 4 (GG4), the new screen protector promises twice the toughness provided by Gorilla Glass 3.

GG4 can be guard against cracks and scratches better than its predecessor considering the fact that the new display protector has been developed after conducting multiple drop tests of smartphones, on rough surfaces such as concrete.

The GG4 is also expected to survive drop tests from a height of as much as 1 meter, that too on rough surfaces.

During the drop tests (the Gorilla Glass 4 wrapped display directly made contact with the rough surface), Gorilla Glass exhibited toughness in the following ways:

  • GG4 survives up to 80 per cent of the time
  • GG4 was found to be up to two times tougher than competitive glasses, in comparison to Soda-lime glass as deployed in today's commercial devices breaks nearly 100 per cent of the time.

"Corning Gorilla Glass has outperformed competing materials, such as soda-lime glass and other strengthened glass, since it was introduced in 2007, and we're always innovating to push the limits of what glass can do, stated James R Steiner, senior vice-president and general manager at Corning Speciality Materials, in an official news release.

Corning also indicated about GG4 protecting future smartphones really quickly, as product sampling and shipments of the display protector are currently underway, across the world.

Gorilla Glass dominates: GG4 vs Apple's Sapphire screens

According to Corning, more than 40 different smartphone manufacturers have implemented Gorilla Glass in nearly 1,395 smartphones. Also, Gorilla Glass is said to have featured in nearly 3bn devices worldwide.

Technology giant Apple, was expected to showcase its iPhone 6 and iPhone 6 Plus smartphones protected with the unbreakable Sapphire screens, but buyers did not get to see this aspect.

Now, with GG4 about to debut, Apple could introduce newer devices with Sapphire screens.

In summary, smartphone users should be the winners in the screen protection battle, as smartphone screens are set to get enhanced protection, in the near future.
