The LG G Flex 2 has an intriguing curved design that allegedly makes it harder for the screen to shatter when dropped face-down. It retains the 700mm curvature radius of its predecessor, but LG went to great lengths to ensure the phone is way more compact, introducing a smaller, 5.5" display, and thinner bezels all around. Not only that, but the arched back cover can be pried off now, revealing a microSD slot for storage expansion - a marked improvement over the sealed G Flex original.
The LG G4 also has an arched design, but it went through its fair share of drop tests, and those didn't result in any remarkable durability when the phone is dropped face-down. The G Flex 2 hasn't been dragged through much torture so far, though, plus there are so many variables in a drop test, that you can rarely grasp how your particular unit will behave from one. How about running a 10-tonnes roller over it, however? Will the curved design survive the pressure? Check it out.
