Samsung To Reveal This Month What Caused the Galaxy Note 7 Smartphone To Catch Fire - Report (reuters.com) 131

One of the biggest mysteries of 2016 will come to an end sometime this month. Samsung will make public the results of its months-long investigation into what caused several Galaxy Note 7 smartphones to turn into flames later this month, according to a report on Reuters. From the report: The South Korean firm said in October it was examining all aspects of the phone, suggesting there may be a combination of factors that contributed to one of the costliest product safety failures in tech history. Samsung has also previously noted that it was working with several third-party sources and experts to figure out what could have caused the error. A popular theory among many is that Samsung attempted to further slim the form factor of the Galaxy Note 7, which resulted in the battery to be held too tightly within the device -- which in turn, caused the layers of lithium cobalt oxide and graphite to touch.

      • It's not that odd. If they can pop out the old battery and put in a new, safer one, why shouldn't they? Gives them something a lot more unique than a "courageous" iPhone. And once you mod it to take replacement batteries, you don't have to replace it because the battery won't hold a charge. And since it won't get updates, you won't experience update slowdown obsolescence. How many updates are "must have" anyway?

What's certain is that the public and the authorities need a good plausible explanation (whether true or not) so they can feel safe and begin to trust Samsung again.

      It was a quite rare problem, obviously frequent enough to warrant the recall, but uncommon enough to not be caught in QC. To be sure of the cause of the problem (rather than guessing like they did for the first recall) they may well have needed to make a number of slightly modified phones to determine which factors were the cause as given the infrequent failure rate trying to monitor one failing is likely to be impractical.

        The fires in the "fixed" Note 7s (which used a battery from an established Chinese manufacturer) were a bit of a surprise. But from what I gather, the number of incidents was extremely small, possibly within the range of random chance. And Samsung pulled the phone entirely simply because they felt the brand name had been too damaged.

        It was not random chance. There were several incidences where the replacements also burned up, and even if Samsung shipped a million, that's still a lot higher than other smartp

      • Because I'm sure when Samsung started their battery group, they picked a bunch of random people and sent them to "Battery School". Once they graduated, they immediately started creating the batteries for the Note 7.

        Or maybe they hired engineers from other companies and institutions that actually had experience in battery design.

        Also, when the second rev of the phone began failing, I'm sure they pulled the whole product and created a massive PR fiasco because they just felt like giving up, and not because p

    • If Samsung didn't know from their internal engineers within 2 weeks of the problem, they have a shitty engineering/QC organization.

      If you rush to do a RCFA on a failure that caused this kind of loss to a business then you have a very shitty engineering / QC organisation.

      Engineers love jumping to conclusions. It's amazing the number of times they get it wrong, don't find the true underlying cause, or don't find very valuable leanings in the process. The fact that they haven't answered this question yet shows they have a far more serious engineering / QC organisation than you will ever know.

    • When catastrophic failures of this type occur, the evidence left is typically a pile of ash and molten metal. It's difficult if not impossible to determine root cause of such a failure.

      They may be inductively thinking and producing a similar failure by applying force to the battery, causing it to fail in a similar manner. However, I'm doubtful that they can determine with certainty what caused a pile of ash/molten metal to have failed.

    What's up with this 'thinner' obsession?

    Everybody I know uses either a fat battery-cover to have more power or an armored cover to protect the slim phones.
    And as for tablets, I prefer the fat toddler-covers which allow a much more relaxed grip on these ultra-thin tablets.

      Well, let's separate out utility value from design value. A thinner phone is somewhat more convenient all things being equal, but thing's aren't equal. We're obviously at the point where many consumers would prefer a marginal improvement in robustness over a marginal reduction in thinness.

      But you've got to get people to buy the thing, and part of that is to make them say, "Wow this is new," when they hold the device. It doesn't take a lot of creativity to make them say that by making the phone thinner than the one they currently carry. You must make it thinner than the last generation of phones. So the usefulness of more thinness isn't for the user, it's for the salesman.

        All things being equal, thinner isn't better (on electronics, lets make sure we're all on the same page here). As nospam points out, the new iPads are so frigging thin and slippery that they are hard to hold. They look nice just siting there but they're a PITA to use. Maybe they really are like people. Although it's nice to think of them naked, the real world goes a lot more smoothly if they are covered with something.

          Phones and tablets are held differently so "too thin" is a totally different question in either case. A tablet you hold in across its thickness; a phone you grasp across its width. If there were a fad for narrow phones there are only so narrow you can make them. But you can keep making phones thinner until you have to worry about paper cuts. It's just not that marginally useful.

            I didn't put mine in a bulky case for its protective properties. I put it in a case so I could hold it without dropping it. The shiny rounded edges are slippery and significantly more difficult to hold securely while juggling other things. A Thule X3 case has nice, easy to grip sides. So that's what I put on it.

          No they don't. Go on the MacRurmors forums and people there are actually clamoring for a thicker phone, because they hate the bump that the camera unit causes on the back of the device, not allowing it to sit flat on a surface. I personally don't see why that would be such an issue (since they're likely to have a case on the back that prevents the camera from touching the surface anyway). They also want more durability after the iPhone 6 "bendgate" and more battery, along with thinner bezels on the device.

        Actually, no. The most convenient design is the one that doesn't slip out of your hands easily and break. Excessive thinness is actually a big contributing factor to the use of cases. The thinner the phones have gotten, the more people have used cases. I used my original iPhone without a case for much of its life and never came close to dropping it. I tried to use my iPhone 5 without a case after the holster broke, and I nearly drop

      The thinner the device in the chunky case the thinner the whole assembly is too. Imagine attaching those protective cases to brick-like phones. Not the same, is it? In the past the brick was the phone. Now the brick is made up of all that padding you attach to it to keep it safe. If they can make some progress regarding the padding, to make it thinner yet as efficient, then you get some sweet pocket padding device.

The aluminum blocks reception, and there are various ways of coping with it, typically by compromising the solid aluminum back with other materials.
