The South Korean tech giant disclosed in a report that when they tested  in more than 300,000 Galaxy Note 7 smartphones, it noticed that there were major defects in two packs of batteries which were from different manufacturers which made the devices prone to fire.The company however took much responsibility for failing to ensure that design specifications given to its suppliers were fatal.

Samsung’s Exponent principal scientist Kevin White said in the report that the negative electrode winding in the battery of an unnamed “manufacturer A,” who first supplied the batteries for the Note 7 phones, were found to be damaged and bent over because the cell pouch did not provide enough volume to accommodate the battery assembly. This also included inadequate welding by the manufacturers.

Even with the Note 7 having one of the biggest battery capacities for a smartphone, Samsung said the company and outside inspectors found no single evidence that the high energy density alone was to be among the reasons.

The Note 7 product failure wiped $5.3 billion off its operating profit, but currently procedures have been put in place to avoid a repeat of the same issue. However this came with other predicaments like the release of Samsung’s yearly flagship which normally is released on February and this time round it was confirmed there would be a delay. The Galaxy S8 was to be unveiled at the Mobile World Congress (MWC) trade show in Barcelona, which begins on Feb 27. Nevertheless, those plans were cancelled and we expect the Galaxy S8, some time this year. This was done to enhance product safety following the investigation into the cause of fires in its premium Note 7 devices.

The company recalled about over 3 million Galaxy Note 7 phones therefore around 4 per cent, or 120,000 units, of the recalled Galaxy Note 7s have not been returned. It also pointed out that it will seek advice on battery safety and innovation from a group of battery experts.
