Samsung Knew a Third Replacement Note 7 Caught Fire On Tuesday and Said Nothing (theverge.com) 110
If you had started to feel sympathetic for Samsung, or safer with the Note 7, its latest flagship smartphone, don't be. Another replacement Samsung Galaxy Note 7 has caught fire, making it three of such incident this week alone. Read how poorly Samsung has dealt with the situation, via The Verge: This one was owned by Michael Klering of Nicholasville, Kentucky. He told WKYT that he woke up at 4AM to find his bedroom filled with smoke and his phone on fire. Later in the day, he went to the hospital with acute bronchitis caused by smoke inhalation. "The phone is supposed to be the replacement, so you would have thought it would be safe," Klering told WKYT, saying that he had owned the replacement phone for a little more than a week. "It wasn't plugged in. It wasn't anything, it was just sitting there."The most unsettling part is that Samsung knew of Klering's phone, and didn't say anything.

So what is the real culprit here? I thought it could have been from using the wrong charging IC or someone in the battery department changing the chemistry and not telling the EEs. But they are catching fire without charging.
Lithium chemistry batteries are finicky little bastards. They are not just dangerous from over-charging (or charging too fast), but also from over-discharging and discharging too rapidly. If they are drawing 1A from a battery that is only designed to handle 1/2A, or worse, if their control circuitry allows the battery to fall below a minimum voltage, then the batteries can go into runaway thermal overload.
My Samsung S5 came with a 2A charger.
Thought at first that was the reason as well, charging too fast.

Makes no sense due to the varying nature of phone ignition, some charging, some not charging, some being used, some not being used. The only thing that sort of follows that is high CPU usage in higher temperatures zones and the CPU to close to a poorly insulated (super cheap) battery. This significantly altering the design operating conditions of the battery allowing increased heat development in the battery in conjunction with the heating CPU. So just an overall bad design, so the Note 7 is inherently a b

Batteries have a higher energy density than explosives.
So does pizza.
For this reason there are many layers of defence. The charging circuitry knows the maximu safe rate.
Figures... if you ate a slice fast enough you'd also catch on fire.
Inside the battery are thermal cut outs. The circuitry of the battery is designed to control the rate of charging. The battery series as a whole should be extensively tested under all sorts of situations and failure cases.. Each batttery should be tested separately. In the case of most failures of the battery then it should simply stop accepting charge and act dead. In order for something like this to happen many layers of design, manufacturing and testing need to have failed pretty disastrously.
There are previous articles describing joint investigation between ATL and Samsung where evidence was found of heating from the phone itself starting the problem.

The alternatives are that a massive mistake led to sending out defective units as replacements without fixing them first, or that Samsung's battery supplier (I think I read that the source all or most of them from third parties) wasn't fully aware of the extend of their problems and have shipped more bad batteries.
Or that they didn't correctly identify the root cause, but grabbed the first possible cause as gospel, and went from there.

When there are vehicle defects discovered that are known fire hazards vehicles are recalled and people DO get on TV and send letters and make telephone calls to let people know to get their vehicles fixed. The same to varying degrees applies to every other product you purchase with known defects rendering the product unsafe.
