    Dong-jin Koh, Samsung's mobile business chief, acknowledged two separate instances of battery malfunctions were to blame for some of the handsets catching fire.

    Koh explained in the first set of batteries, which were rolled out with the original devices, there was an issue with the upper right hand corner of the battery cell. "Our analysis showed the main cause for the incidents was deflections in the negative electrodes," he said, adding incorrect positioning of the negative electrode tip also led to a higher likelihood of incidents.

    For the second set of batteries, which were supplied by a different manufacturer and were put into the replacement units, Samsung found melted copper on the negative electrode area. Koh said there were welding issues that led to contact between the positive and negative layers, resulting in short circuits.
