[Note 7 Questions & Answers] br0adband:
As for the investigations of devices that have actually failed, I would imagine the first thing they'd want to do is get the device to Samsung since that's the only qualified entity that could say for sure what happened when they complete the investigation. Turning it over to a local fire department might end up with them just saying "It overheated and it caught fire, case closed" which is obviously not enough of an investigation at all. It's got to be done right or else it's just a waste of time.

I have to go back to the big point that so many people are dismissing: Samsung is losing an absolute fortune over this, a huge huge amount of money over this whole situation and they're doing it because it actually is the right thing to do since they probably don't know why this is happening yet either. They can't take a chance on leaving the Note 7 out there in the wide wild world (yes I said wild there on purpose) and people potentially getting hurt or property potentially being destroyed - they're doing what they have to do to so the potential of injury or damage is curtailed as much as possible.

Now that the recalls are in place, it's up to the consumer to keep the device or return it.

There's really not much Samsung can do at this point in time except work on their investigations. Such things are generally considered to be secret until they end up with some results to share - posting anything right now that's not 100% concrete and verifiable and reproducible doesn't seem to serve any purpose in my opinion but to scare people even more than they might already be.

JerryRigEverything has proven himself to be a considerate intelligent well-spoken individual that's producing videos designed to help consumers make a buying decision more than anything else. If he screws up he's always come out as soon as possible with a correction, which is exactly what happened with the recent scratch test thing. He realized there was a problem, he worked on figuring out what the problem was, he formulated his response so that people would understand it very easily, and then he posted it. I give the guy high marks because he's proven himself to be honest and trustworthy in his time of making such videos.

Contrast that with someone who might just post a shaky blurry not very clear video that is barely recognizable in some respects screaming into the mic or just screaming in general about a Note 7 or some other device that's got a problem. If it's a one-shot one-time video there's no history of credibility to work with so it becomes a questionable thing, at least to me.

Defects happen, that's a fact, sometimes they only happen to one in a million devices, sometimes it's more serious. Not everyone that's had a problem with the Note 7 so far has posted a video on YouTube or spread images of their devices or posted blogs about the experiences - instead, they contacted Samsung and probably their carriers and returned the devices without any fanfare or public awareness at all.

Just because something happens doesn't mean everyone on the planet or the Internet is going find out about it the second it happens, thankfully.

As for why we're impatient and we want answers now, that's simple: we're an instant gratification society and it's getting worse. I just said it's a good thing that not everybody posts something 24/7 instantly just because they can, the sheer level of noise if that becomes a reality would be truly deafening in every respect possible.

It's ok to be patient, really, it's not like we have a choice. When Samsung knows what the problem(s) is/are then the rest of the world will too, or at least as fast as they're able to get a press release or public statement out.
