It came to that moment when Samsung doesn’t even have to make announcements about the device being fire hazard. The number of returned units is really huge and we still have to wait to see what will happen next with the remaining 4% of the units.
In near future, Samsung will be also releasing detailed report on what caused such terrible failure on the Galaxy Note 7. Besides that, it is still unclear whether the 96% of the devices returned is worldwide, or is it just in the US.
These informations are coming from the official Samsung announcement.
