By now it's no secret that Samsung has had quite a few issues with the Galaxy Note 7 since a couple weeks after it launched back near the end of August. Within the first week of September the phone began having issues with overheating, which led to phones catching fire that caused property damage and some injury to various users. Eventually this resulted in Samsung issuing a formal recall and replacing devices. Over the past week and half, Samsung has now issued a second recall due to the replacement phones having the same problems, and now the Galaxy Note 7 is done as carriers and retailers have pulled the phone from shelves while Samsung has halted production and asked global sales partners not to sell or exchange the phone. In the near future, Samsung will be explaining the cause of the exploding devices.
While it's known that the battery was overheating and that led to the end results, there's no official detail yet on why the replacement phones have been exploding as Samsung switched battery manufacturers and assured customers that the devices were safe. That wasn't the case, though, and it's caused quite a bit of damage both to people's belongings and to Samsung's reputation. While Samsung is likely doing much to prepare to fight to keep customers that may have been turned off by these events, this scenario will start with detailing why the replacement phones had these issues which they have noted will be happening in "the coming weeks."
That of course is a bit vague, but an exact time frame is perhaps less important than the fact that Samsung will be be explaining what went wrong. As noted by Samsung, they're investigating the problems at the current time and they don't want to speculate on what caused the issues. A couple or a few weeks from now seems to be long enough where Samsung feels confident they can track down the root issue and relay those details to the consumer. Although the battery is likely thought to be the main problem, there's no telling if other factors had a hand in the defect. It's currently rumored, for example, that the curved edge glass screen is to blame.
