And when it is edgless curved/bent this increases chances of cracks:

''devices that curve down at the edges are more prone to damage''

''Consider a semi-thick strip of material that is bent. On the inside of the bend you will have compression, and the outside of the bend you will have expansion - it's the differential between the expansion and compression that causes the fracture between the compression and expansion areas.

''In a perfect world, we would be given the option of either a Gorilla Glass scratch-resistant screen or an acrylic (or something similarly plastic-like) screen that is more shatter-resistant. I would certainly pick the latter because I have never had to replace a phone because the screen was too scratched''
