Samsung Elec says battery caused Note 7 fires, may delay new phone launch
Wrapping up its months-long probe into the cause of the Note 7 debacle, the world's top smartphone maker said faulty batteries from two suppliers were to blame for a product failure that wiped $5.3 billion off its operating profit.
"The lessons of this incident are deeply reflected in our culture and process," Koh told reporters at a press briefing. "Samsung Electronics will be working hard to regain consumer trust."
However Koh said the Galaxy S8 would not be unveiled at the Mobile World Congress (MWC) trade show in Barcelona, which begins on Feb. 27, the traditional forum for Samsung premium product launches. He did not comment on when the company planned to launch the new handset.
Investors have been looking to the investigation into the Note 7 failure to reassure consumers that the company is on top of the problem and can be trusted to fix it.
Samsung's reputation took a hammering after it announced a recall of fire-prone Note 7s, only for reports to emerge that replacement devices also caught fire. Images of melted Samsung devices spread on social media and airlines banned travellers from carrying them on flights.
The handset, Samsung's answer to Apple Inc's iPhones, was withdrawn from sale in October less than two months after its launch, in one of the biggest tech failures in tech history.
Investigations by internal and independent experts ruled out problems with the Note 7's hardware and software, Samsung said.
Instead, manufacturing and design defects in Note 7 batteries caused short-circuiting, Koh said.
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). SDI said in a statement it would invest 150 billion won ($128.56 million) to improve product safety and expected to continue to supply batteries for Samsung phones.
Samsung said it accepted responsibility for asking battery suppliers to meet certain specifications and did not plan to take legal action against them. The company touted longer battery life and fast charging as major improvements when it launched the Note 7.
Among other measures to boost safety, Samsung said it had implemented an eight-point battery check system to avoid any such problems going unnoticed in future.
While Samsung Electronics' mobile division is expected to have bounced back from the Note 7 failure during the fourth quarter, investors remained cautious about the outlook for sales of future flagship devices.
"I think they did enough to convince most consumers that they knew what happened and can prevent future issues," said Patrick Moorhead, president of technology analyst and advisory firm Moor Insights & Strategy.
Samsung Electronics shares were up 0.6 percent, while the wider market was down 0.1 percent as of 0341 GMT.
The South Korean firm expects fourth-quarter operating profit to hit a more than three-year high, driven by booming chip sales. That forecast pushed Samsung's share price to a record high this month.
Samsung will announce its final earnings figures on Tuesday.
