On Sunday, Samsung’s mobile chief, Koh was joined by UL, Exponent, and TUV Rheinland, three independent testing firms that came to most of the same conclusions as Samsung — that it was the battery, and not the phone’s design or Samsung’s manufacturing process, that cause the Note 7 battery issues.
Sure, blame the batteries. But it’s not quite that simple. During the press conference Sunday, Samsung said two separate battery defects caused both the original batch of Galaxy Note 7 phones and the replacement units to overheat.
The first battery, it said, suffered from a design flaw. The battery’s external casing was too small for the components inside, causing it to short-circuit and ignite.
The second battery, which came from another supplier, didn’t have the same flaw, Justin Denison, head of product strategy and marketing for Samsung’s US arm, said in an interview ahead of the press conference. In the rush to pump out enough batteries for the replacement units, though, the supplier introduced a manufacturing defect that led to the same result, he said.
The Sunday press conference marked the start of a Samsung campaign to rebuild company credibility, which will include the upcoming launch of the flagship Galaxy S8 phone, as well as another Note later in the year.
