MKBHD Goes Hands-on With LG G Flex Self Healing Back, Even Takes a Knife to it


Just last week, we got a good look at the “Self Healing” backside on the G Flex from LG, but given the video was straight from the manufacturer, it hardly ever relates to real world usage. Our buddy MKBHD got his hands on the new device from LG and decided to test out the self healing functionality himself. With the help of some normal keys and even a pocket knife, we can see just what the G Flex is made of. 

As we can see in the video, after being scuffed and scratched by the keys, the backside has little problems returning back to a normal look after a few minutes pass. When it comes to cuts and deep scratches from a knife though, the device does its best to look good, but it isn’t be able to revert back to perfect condition. As pointed out by Marques in the video, the material reacts very well to heat, which should speed up the healing process. So, if you drop your baby and you see some scratches, try rubbing them out. That sounds dirty.

    i’m not gonna do that to my curved-back Xperia V hahahah

    This is the cell phone Wolverine uses to make calls.

    Nice Spidey.

  • sk3litor

    This actually looks like a really nice phone.

  • DoctorJB

    Seems like this would be even better for the screen. Is there transparency issues that prevent it?

    • zurginator

      Transparency and texture issues. I suspect it’s a very soft, rubbery material.

  • Chris Amaya

    His fingers look cell shaded in some shots lol

  • ok

    Reminds of of the self healing paint on infinitis except it works.

  • the guy

    its a self healing polymer… DARPA has been working this type of material for their planes

  • Does it have to be a phablet?

  • joejoe5709

    Very cool stuff.

    Flexible Chassis + Self Healing Casing + Durable “Flexible” non-Glass Display + Waterproof NanoCoating = Zero need for a screen protector or case.

  • jadeveon da destroyer

    I am impressed, seems legit, what more info on what the coating is that fills scratches like that!?

  • PhillipCun

    Very impressive LG… now stop copying Samsung because you really don’t need to…

    • Tim242

      This device is far from a copy. The Galaxy Round is curved for rt he sake of being curved. This device is curved vertically, and flexes.

      • Good_Ole_Pinocchio

        I think he’s talking about their UI stuff and accessories

      • JMonkeYJ

        DisplayMate has a very interesting analysis of the Galaxy Round:
        which shows how the curve has some nice picture quality improvements. I still think it’s kind of silly for some other reasons, but I found the article enlightening. In general DisplayMate has pretty great display shootouts and information.

      They should start copying Nexus devices or better yet Motorola.

      • Hothfox

        Well, didn’t LG design the latest Nexus? And the previous one?

      • michael arazan

        Just don’t copy the Nexus battery or camera

    • AaronD12

      Copy? Samsung? Heh… surely you jest…

  • Chippah

    COMING TO VERIZON! = never…….
    They cant even launch a WHITE variant of thier own LG G2 FFS!

  • Allen Byrd

    This thing really reminds me of the GNex.

    • jadeveon da destroyer

      they are both grey?

      • Allen Byrd


    • droidify

      I think the shape does resemble a Gnex. It’s definitely a more extreme curve, but it still sort of favors it.

    • Hothfox

      I really did like the GNex except for the AMOLED screen (that cause super battery drain for me, even with the brightness all the way down and developed a case of burn in right before I replaced it) and the weirdly textured battery door. It was a great little device.

  • RhinoShock

    It was really weird watching the LG promo and seeing the back of it just passively fix itself. I knew there had to be some variable that led to it fixing the scuff and it’s cool MKBHD figured out it was heat via their testing environment info. Too bad about knife scratches though; don’t bring a phone to a knife fight i guess lol.

    • Cowboydroid

      The variable isn’t heat. It’s chemistry. The molecular structure of the polymers in the plastic is what allows it to heal. Heat simply speeds up the process.

      • triumphtriple

        A variable is a parameter that can change and effect the outcome.The temperature changes and effects the rate of healing and thus is a variable. The molecular structure is constant, and thus is not a variable.

        • Cowboydroid

          That’s true…but he did not use “variable” in its scientific manner.

          • triumphtriple

            Point taken.

  • Steve B

    If all else fails, I always resort to rubbing one out…

    • ToddAwesome

      you forgot to drop the mic

      • Steve B

        Your girl is too busy speaking into it…oh!

        j/k 😉

        • ToddAwesome

          that escalated quickly.

          • Steve B

            You know I kid

    Rubbing them out never works for me. Oh god….Why’d I say that.
