Three months after its largest-ever recall, Samsung has finally completed its investigation of the Galaxy Note 7 fiasco. The high-profile flagship phone was recalled (twice) and canceled after reports of explosions and fires, and now Samsung thinks it has finally nailed down the issue.
Samsung's verdict: two separate battery construction issues were to blame. Samsung Electronics used two separate suppliers for the Galaxy Note 7-Samsung SDI, a sister company in Samsung Group, and Amperex Technology Ltd (ATL) - and it turns out both manufacturers had their own issues. Given that Samsung's first recall and attempted fix didn't work, it's no surprise that the problem behind the Galaxy Note 7 is a complicated one.
