Samsung said its executives and independent experts will disclose their findings in a press conference in Seoul and that the company will unveil new measures that have been implemented to prevent repeat incidents.

The head of it mobile business, Koh Dong-jin, who announced the initial September Note 7 recall, will attend the briefing, Samsung said in a statement on Friday.

The world's top smartphone maker needs to reassure consumers that its devices are safe in order for the company to recover from a projected almost $5.20 billion hit to its operating profit from the Note 7's collapse over three quarters.

Investors say Samsung must give a convincing explanation for the fires before the launch of its Galaxy S8 smartphones, expected sometime in the first half.

The company initially announced a recall of some 2.5 million Note 7 phones in September and identified the cause of the fire as a manufacturing process problem at one of its suppliers, later identified as affiliate Samsung SDI Co Ltd.

But new Note 7s with what Samsung said were safe batteries from a different supplier continued to catch fire, forcing the firm to permanently halt sales. The firm in October said it would examine all possible causes and hired third-party firms as part of its probe.
