Where do we even begin? Samsung faced a slew of challenges in 2016 but nothing hurt more than the nightmare that was the Galaxy Note 7 smartphone.

In October, Samsung (SSNLF) halted all production of the device following complaints that it burst into flames. This came after a badly mismanaged recall of 2.5 million Note 7s shortly after it launched.

Now, you can't even bring one on a plane without being it taken away.

Analysts believe the Note 7 debacle will put a $9.5 billion dent in sales and eliminate $5 billion in profits.

Samsung also recalled 3 million of its washing machines this year due to an explosion risk.
