Galaxy Note 7 became Samsung’s biggest product disaster when batteries spontaneously caught fire/exploded (2016), leading to global recall, FAA flight bans, and $5B+ losses. The device was excellent otherwise, but battery defects caused property damage, injuries, and PR nightmare. Samsung’s handling (full recall, apologizing, investigating) became case study in crisis management, while Note 7 became punchline and cautionary tale about rushing products.
