Samsung may blame battery size for Galaxy Note 7 phone fires

Samsung announced Friday that it's finally going to reveal what caused its Galaxy Note 7 phones to catch fire and explode.

The company stopped making its flagship phone in October, after two messy rounds of recalls that asked customers to turn in their smartphones - and then the 'safe” phones issued to replace them.

Samsung will give its account of what happened in a news conference Monday in Seoul, which will be Sunday night in the United States.

While the company has not given any details of what it will say, it is expected to reveal that the initial fires were caused by the irregular size of the battery, the Wall Street Journal reported, citing several unnamed individuals.

A second round of smartphone fires linked to the Galaxy Note 7's replacement phones - which had batteries made by a different company - were apparently due to a 'manufacturing issue” that took place because the phones were made too quickly, the Journal article said. The inquiry was conducted by Samsung and outside investigators hired by the company.

Samsung declined to comment on the Journal article.
