In YouTube personality / video producer Marques Brownlee reportedly tested the device to check for its ‘self-healing’ coating with a number of tests, including scratching the smartphone with a knife.
According to The Verge, in the first test, Brownlee uses a set of keys to mark scratches on the G Flex, which are essentially ‘healed’ with the marks almost invisible to the naked eye.
However, when he carves out a deeper scratch using a knife, the device ‘half heals’ them, making the scratches appear far less visible than it would on a regular phone.
Brownlee explained that LG’s own promotional clip for the ‘self-healing’ coating wasn’t a sound theory for why the results weren’t perfect, as it was filmed in a controlled temperature environment with a thermostat set to 81 degrees Fahrenheit.
He further said that the ‘self-healing’ coating isn’t as effective in cooler climates and may not work exactly as advertised, yet it appears as a positive step towards the everyday durability of smartphones, the report added.
