Samsung Galaxy Note 7 explosion details officially revealed

The company is now gearing up with to launch its new flagship smartphone - Galaxy S8 in April this year.

Keeping in view its Galaxy Note 7 debacle and its latest findings, Samsung has made a decision to implement additional safety protocols and an 8-Point Battery Safety Check routine to ensure battery safety.

According to a press release, Samsung uncovered two separate sets of flaws with its batteries.

This conclusion was supported by investigations conducted for Samsung by testing and certification organisations UL, TUV Rheinland and Exponent.

In short, no. While the faults were squarely within the manufacturing and design of the batteries, the Note 7 design didn't directly impact upon the failures, though Samsung's specifications for the batteries might have indirectly led to the failures.

Samsung didn't specify what steps in its quality assurance process are new versus the steps it was taking during the Note 7's assembly, though. But welding defects in "some incident cells were found to be tall enough to bridge the distance to the negative electrode foil", raising the possibility of short circuits and self-heating, White said. The battery's structural problem and manufacturing problems were the main cause, he said.

But, it added, internal and independent investigations had "concluded that batteries were found to be the cause of the Note 7 incidents". As it turns out, the batteries are to blame. Last year, the company released the Note 7 in August.

Samsung Electronics did not name the battery suppliers on Monday but previously identified them as affiliate Samsung SDI Co Ltd and China's Amperex Technology Ltd (ATL). For example, the company didn't explain why it initially stated that some phones were exploding due to "external factors" rather than battery issues.

In the case of the original battery, the casing was too small, causing it to short-circuit and ignite. The second round of batteries, which came from a supplier in Hong Kong, had no flaws in the design.

Yet Samsung's president of mobile communications DJ Koh declined to throw the battery-makers under the bus, saying that Samsung the Note 7's design called for a 3300 milliamp hour battery "in a more compact form compared to previous Note models".

Most significantly, Samsung says it's developed an eight-point battery safety check that will include visually inspecting each battery, x-ray batteries to search for abnormalities and large-scale charging and discharging tests.

The company has confirmed that it will be not launching the Galaxy S8 series during the trade show.
