Corning Reveals Gorilla Glass 4, Promises No More Broken IPhones

An anonymous reader writes "Corning introduced next-generation Gorilla Glass, which it said is ten times tougher than any competitive cover glass now in the market. The company says that the Gorilla Glass 4 so launched is to address the No.1 problem among the smartphones users- screen breakage due to everyday drops."

      Toughness is a perfectly good engineering term with a defined meaning. Look it up. Wikipedia is a decent start. "In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing."

      It's typically measured by an impact test.

      Actually, even the Wikpedia article you linked gives multiple definitions for toughness, depending on application. Which one is used here remains poorly specified and opens up the possibility of ambiguous marketing platitudes. Now, if they said shear strength was improved overall by a certain percentage, that would be information.

      Oh you silly slashdotter. Sure, you may have studied materials science and engineering, but do you have the real world experience? In the modern corporation it's all about teamwork. Well-managed teams can do more than any one person possibly could. In this case, the engineers make the glass hard. Then marketing adds the flexibility. See? Teamwork. Oh yeah, and management makes it all happen and does extra janatorial tasks like mopping up the excess bucks.

    If you have a naked phone, what do you expect?

    Fuck, I drop mine at least one a month onto something solid. Of course if it hits a stone, or the edge of a rough surface, it's going to scratch or shatter.

    Put it in the most basic of cases so the force (not the sharpness) goes to the screen and it's fine. I have never, in my life, broken or scratched an electronic device like that.

    And, honestly, yes, I've had some doozies! When you phone cartwheels down a set of marble staircases in a hotel, and smashes so hard every component falls out, you think it's game over. Pick it up, put it back together, all works just fine.

    What phone? Galaxy Ace (the cheapest junk you could buy at the time), S4 mini, etc..

    Electronics don't survive mishandling. But a four-foot drop onto concrete is nothing. Absolutely nothing. Your pen survives it. Your USB stick survives it. I've seen laptops survive it (but that's mostly luck, admittedly). But your remote controls don't shatter into a million pieces when you drop them off the sofa. I've seen plates and bowl survive worse unscathed.

    It's all a matter of dampening and removing the sharpest points. It takes one, tiny, shard of stone a few mm tall to be the pressure point that smashes your screen. Put it in the cheapest case from Amazon, it's covered with 2-3 mm of foam or board, no more pressure point.

    I have launched phones (accidentally) across entire school playgrounds. Not once have I broken one, except once the plastic on the battery catch went loose and I had to pay about 1GBP to replace it.

    Phones used to have raised edges, the screen would be the last thing to contact the floor. When you have a phone where the front is entirely glass, edge-to-edge, nothing is going to save you if you drop it. Except putting a wrap around it.

    I blame Apple "design" again - yeah, looks pretty. Totally fucking impractical, however, and unfit for purpose. Gimme a 2mm raised edge around it and I'll never have to replace the screen. Fuck, just unpacking iPads and iPhone from the box can be a hazard because their "design" teams didn't think to put fucking fingerholes in the packaging. You either have to shake the thing upside-down or tear your brand-new box. I know, I unpacked 200 over the summer for the school I work in. It was a damn nightmare.

    Apple's takes "design" to mean "looks pretty". I take it to me "is a good engineering way to make this device that makes it look pretty as well as be user-friendly". Stop making phones with edge-to-edge glass if you expect people to use them in the real world. I'll happily pay the cost of an Apple device for a Samsung device that has a completely rubberised raised exterior.
