After months of investigation, Samsung has finally revealed what caused a number of Galaxy Note 7 smartphones to catch fire; two distinct battery flaws.
The Note 7’s original batteries were manufactured with casings too small to fit the device’s electrode assembly, which led to some devices short-circuiting.
Samsung recalled the Note 7 following a number of reports of the devices catching fire and replaced the faulty batteries with safer models.
However, the second line of batteries contained welding defects that once again led to the short-circuiting of some devices.
Samsung has apologised to its customers for the faults and vowed to improve its manufacturing and inspection processes.
