He was joined by three third-party expert organizations – UL, Exponent, and TUV Rheinland – to present their independent investigation results.
Koh stated, "Through a large-scale testing facility where approximately 700 Samsung researchers and engineers replicated the incidents by testing more than 200,000 fully-assembled devices and more than 30,000 batteries, Samsung finally concluded the cause of the issues.
Our investigation, as well as the investigations completed by three independent industry organizations, concluded that the batteries were found to be the cause of the Note7 incidents. Nonetheless, we provided the target for the battery specifications for the innovative Note7, and we are taking responsibility for our failure to ultimately identify and verify the issues arising out of battery design and manufacturing process prior to the launch of the Note7.
We have taken several corrective actions to ensure this never happens again, including the implementation of a multi-layer safety measures protocol at the product planning stage, and an 8-Point Battery Safety Check."
