Samsung Galaxy Note 7
The Samsung Galaxy Note 7 launched August 19, 2016 as Samsung’s flagship phablet, featuring a 5.7” curved QLED display, iris scanner, IP68 water resistance, and refined S Pen stylus. Reviews were glowing—until devices started exploding in users’ hands, pockets, and bedside tables.
Battery Explosions
Reports emerged in September 2016 of Note 7 batteries overheating, catching fire, and exploding. A Florida man’s Jeep was destroyed by a Note 7 fire. A Southwest Airlines flight evacuated after a Note 7 began smoking. Samsung recalled 2.5 million devices on September 15, offering replacements with “safe” batteries.
Replacement Phones Also Exploded
Replacement Note 7s also caught fire. A replacement unit exploded on a Southwest flight (October 5), prompting the FAA to ban all Note 7s from U.S. flights—unprecedented for a consumer device. Samsung permanently discontinued the Note 7 on October 11, 2016, after just 53 days on sale.
Root Cause
Samsung’s investigation blamed dual battery defects: the original Samsung SDI batteries had design flaws (insufficient separator space), while replacement ATL batteries had manufacturing defects (poking the separator). The aggressive thinness and large battery capacity (3,500mAh) left no room for error.
Financial & Reputation Damage
The disaster cost Samsung $17 billion in lost revenue and $5.3 billion in recall expenses. Samsung’s mobile division reputation tanked, though Note 8 (2017) and Galaxy S8 eventually restored confidence. The incident validated the need for rigorous battery safety testing across the industry.
Memes & Pop Culture
“Note 7 grenade” memes flooded social media. The TSA confiscated Note 7s at airports. Hotels banned them from rooms. The phone became shorthand for catastrophic product failure—Samsung’s Edsel or New Coke moment.
