I own 2 note 7s, one i charge with a 3rd party charger and the other with the original (the one with those drops), both have fast charge disabled.
I boxed up this one for sure, and now i am boxing the other one although is has no issues whatsoever but i travel a lot and carriers are not allowing the phone on the plane.
Some more shots of the same day this did this which does not show any record of what utilized all the power. While the device drained, it got so hot that i could not touch it for an hour.
This Device was bought from the UAE and was made in Vietnam.
