The LG G Flex has a curved display, but it also has another very unique characteristic that makes the device stand apart from the competition. The LG G Flex has self-healing powers where the scratches made on the back of the phone can heal itself and disappear. The technology behind that feature is unknown, but you can see a video above of how it works. The video demonstrates the phone being scratched over and over for 2 minutes. It returns to normal after that. Lots of exciting things are happening in 21st century technology!
