changing its shape if a device is dropped or gets hit. While rubber is used on the Apple iPhone to absorb shocks, other elastic materials could be used as long as the elasticity is enough to protect fragile components in the case of a "large impact" such as a fall from a great distance. The material should also have viscous properties to protect the components from the shorter drops that happen more often. Going back to Apple's iconic smartphone, the rubber coating in the form of a thin bezel has been installed between the display and the phone's exterior bezel.
We all drop our phones and the first thing that we usually check after gingerly picking up the fallen handset is the screen. Anything that increases the survival rate of the display after a drop, no matter how large or small, is going to be appreciated by the cellphone using public.
