I don't know how fatal this will be for Samsung next time they go out and sell phones; but people have got a taste of buying from a company that doesn't have any sales or customer rep centers easily accessible where people can go and complaint. I really hope it doesn't turn out to be fatal for them but I also hope it breaks the Samsung monopoly over Android and let brands like LG, HTC shine.

OLED displays are so good they still sell themselves, and Samsung is the only handset maker that seems to be committed to the technology. I doubt this will change much.

Isn't "burn in" a big drawback for OLED screens?

Why did Note 7's have this problem? I assume the fault is entirely in the battery (?), so did Samsung change how the batteries were manufactured this year? Does the Note 7 have power demands that mean they can't go back to tried and tested battery manufacture? (Hoping there are EE's or manufacturing people here that might have some educated guesses)

I believe Samsung doesn't make the batteries. Whoever does, however, is probably not feeling too good...

It also means that this could've easily happened to another company's phones; remember the laptop fires a few years ago (Apple, Dell, IBM, Toshiba, etc. all issued recalls) that were determined to originate from defective Sony cells?

It still seems to be OK to bring Note 7s on airplanes. Not bottles of water, though, that's too dangerous.

The problem is that with a water bottle, you can immediately see it's some kind of liquid on the x-ray and disallow it during inspection, whereas the Note 7 isn't immediately apparent when inspected from afar. While I don't agree with the liquid ban, it's much easier to ban a liquid than it is to ban a specific model of a phone.

Samsung Electronics doesn't make the batteries - but Samsung SDI do, along with Chinese Amperex Technology (for the third sold in China). My understanding is that both devices with SSDI and with Amperex batteries have caught on fire (IIRC there have been failures inside and outside of China), so maybe a chassis design defect subjecting the batteries to unexpected strain?

Samsung SDI also manufacture iPhone batteries.

What's so great about OLEDs? They consume much more energy and don't produce the most accurate colors.

Properly calibrated OLEDs look at least a lot better to my eye than any LCDs. Much deeper blacks and more pure colors that go past what an LCD can reproduce.

> I also hope it breaks the Samsung monopoly over Android and let brands like LG, HTC shine I have a Nexus S (Samsung), a Nexus 4 (LG), and a Nexus 5 (LG again). As you might guess, I bought those without really bothering to consider who the manufacturer was. The 5, the most recent one, has failed catastrophically and eaten my data. The 4 is suffering from a swelling battery, and will be thrown away as soon as my One…

HTC is done... they accepted to make google pixels without any htc branding. It's not something a healthy company could accept

From what I've read online the newer generation Samsung displays, those from say the last 1-2 years, have supposedly made big strides in dealing with "burn in". Apparently it's much less of an issue now, although still more common than LCD. Also, if I understand correctly, OLED doesn't actually suffer from "burn in" like LCD does, instead it's more "burn out" as the pixels, particularly the blue ones, degrade faster than other colors.

For what it's worth I have a Nexus 6P which uses a Samsung display and I haven't noticed any burn in yet, although I'm probably a very moderate user so that's not really saying much.

Mobile devices have been using custom-desgned batteries for the last 20+ years.

In this case, the battery manufacturer couldn't meet these particular design constraints.
