The most mystifying thing about the Samsung Galaxy Note 7 explosions

Samsung's Galaxy Note 7s keep exploding, and Samsung still doesn't know why. 

When electronics explode, people often default to blaming the battery — because that's usually the culprit. But when Samsung sent replacement Note 7 phones to users with batteries from different suppliers, they still caught fire, the New York Times reported.

So Samsung engineers subsequently tried to "reproduce the explosions," a person familiar with the test process told the Times. They were unsuccessful. 

Samsung has since killed the Note 7 altogether — no sales, no exchanges — and if you have a device on your person, the company wants you to turn it off and turn it in stat. 

While Samsung tries to figure out why its devices keep igniting, the company is watching its market value burn.
