7 surprises in Samsung's Galaxy Note7 smartphone
It's been one of the most discussed technological failures of , but as the dust settles around Samsung's recalled Galaxy Note 7 smartphone, one question remains: what actually went wrong with the phones? Samsung has finally announced the answer or answers. There were two battery manufacturing issues which caused the Note 7 to go up in flames. The first one related to battery size: batteries made by Samsung's SDI group were too small in one corner, causing negative electrodues to be bent and increase the likelihood of short circuiting.
The second issue was with batteries from a third party provider, Amperex Technology Ltd, which were found to be incorrectly welded. Points left on the batteries were able to penetrate protective insulating. Before announcing the findings DJ Koh, President of Samsung Mobile said he wanted to "deeply apologise" for the incident. In a statement Samsung said: "Samsung's investigation, as well as the investigations completed by three independent industry organisations, concluded that the batteries were the cause of the Galaxy Note7 incidents.
After explaining the issues, the South Korean company went on today to announce its earnings in , recording its highest profit jump in three years despite the phone issues. Samsung Electronics, the unit that mobile comes under, saw sales drop around two per cent but overall the company announced its full-year operating profit in was A manufacturing engineering company, Instrumental, investigated the errors affecting the flagship phone last year.

According to Instrumental's teardown of the device, the Note 7's battery didn't have enough physical room for error. Samsung made the battery thinner, removing thickness margins, meaning the separators between the positive and negative layers may have been too thin, increasing the chance of these elements touching and sparking. In addition, Instrumental pointed out that when batteries charge, chemical processes cause the lithium to migrate and the battery to "mechanically swell". Usually, around 10 per cent extra space is required to compensate for this, but the battery in the Note 7 entirely filled its pocket.
This increased the risk of 'explosion'. The design wasn't completely reckless, though. Instrumental noted that the battery sits within a CNC-machined pocket, which will protect it from being affected by other internal components.

On October 10, according to South Korean news agency Yonhap, the company decided to temporarily halt production of the Galaxy Note 7 following talks with safety regulators as the replacement handsets also pose a significant fire risk and health and safety issue. This decision has now been made permanent. Youtuber Ariel Gonzalez shares images of his Galaxy Note 7 phone after it set on fire. Samsung and the US Consumer Product Safety Commission announced a formal recall, meaning that every Galaxy Note 7 unit needed to be returned immediately.
An official investigation revealed reports of 13 burns and 47 reports of property damage directly related to the recall. Figures suggest a total of 1. Samsung advised customers to contact the network operator or shop where they purchased the original device. Alternatively, owners should be able to receive a full refund at their point of purchase. The company offered this explanation at a press event in South Korea Sunday. Samsung did not provide details about its prior quality-control procedures, but the company says it has overhauled its safety testing process as a result of the investigations.
As far as smartphone battery sagas go, this one was packed with twists, turns, and then a whole lot of silence. In September, weeks after the Note 7 launched, Samsung issued an initial recall of 2. By the time the US Consumer Product Safety Commission issued a formal nationwide recall two weeks later, nearly dangerous battery incidents had been reported in the United States.

Instead, Samsung concentrated on making sure people weren't still using the Note 7, even resorting to pushing out updates to all Note 7 phones to brick the devices. Those scooter issues were largely blamed on low-cost batteries —ones that likely had internal flaws and impurities that caused short circuits—that were churned out to meet demand for a hot craze. For smartphone users, that energy density helps give tiny devices long battery life; the Note 7's 3,mAh battery was built to get through a full day.
But every smartphone has a lithium-ion battery inside it, and the Note 7 presented wildcards that stoked speculation.
How to Root Samsung Galaxy Note 7
Samsung said it explored any potential problems involving system software, manufacturing, and Note 7 hardware during its months-long investigation. They tested with the phone's iris-scanning feature turned on and off, downloaded third-party apps to see if that had any effect, and tested to see if USB-C charging played a role.
But all those tests checked out, according to Samsung and independent researchers. Plus, those components are practically the same in any phone. As long as a battery is designed to be fast-charged, it should pose no additional danger.
Whatever perfect storm of power-management failures could have occurred, they shouldn't have caused the battery to explode. Safe lithium-ion batteries have features that mitigate disaster in these types of situations, but short circuits and internal battery damage are harder to defend against. According to Samsung's Koh, the company doesn't just intend to make its own batteries safer.
As part of its new safety procedures, Samsung will safety-test batteries at every point in the manufacturing process. They'll also train employees at every level of the supply chain.
