As i mention in my last post of LG G FLEX that comes with a Self-healing technology, so now i will share this official and non-official videos for you to see and amaze about this mobile.
"LG G Flex has a Self Healing cover that helps the device's back recover from light scratches within minutes. Watch the video to find out how long it takes to heal itself and how durable the LG G Flex is. Also LG G Flex's strong durability restores its original curved form even after it is pressed completely flat."
