Showing no fear, YouTube sensation Marques Brownlee took a knife to the back of his new LG G Flex to test the self-healing feature, and he got some impressive results. 

It turns out LG's technology isn't just a marketing gimmick - scratches actually heal. Simulating real-world occurrences, Brownlee took a pair of keys to the back of the smartphone. And the scratches healed up quite nicely. Being in a cold climate, the self-healing process took a while - that is, until Brownlee warmed the back of the phone with a little friction, which seemingly speeded up the process. 

Getting a bit daring, Brownlee used a knife on the back of the handset to make a deep gash, and even that healed pretty well after a few hours. The scratch wasn't completely taken away, but it looked better then any phone he's tested to date, he says on YouTube. 

The LG G Flex took the world by storm last month when it was announced as the second handset with a curved display after Samsung's Galaxy Round. LG is the first company to include self-healing technology, and by all accounts, it seems to work pretty well for a first-time technology on the market.

The LG G Flex is currently available to customers in South Korea, with plans for a release soon in the US and eventually the UK. Does this self-healing technology make it an enticing option? - PAY MONTHLY PHONES The Samsung Galaxy S10+ is now available on EE who have been awarded the UK’s best network for the fifth year running. RootMetrics tested the four UK networks and EE was faster and more reliable than all of them, with better data performance. Their network has come a long way since they launched in 2012. Back then they had 11 UK cities covered by 4G. Today they cover most of the UK’s land mass, thanks to 19,000 state-of-the-art 4G sites. They’ve got faster, too – from 50Mbps to a maximum speed of 400Mbps. And they’re soon to experience even greater possibilities with the launch of 5G.
