After a thorough investigation that took a few months, Samsung can finally reveal the causes of the Note 7 disaster. All sides of the product, "including hardware, software and related processes," were checked by Samsung and three independent organizations. 

Just as expected, the reason behind the fires was the battery. Sadly, both rounds of fires were caused by batteries coming from two different manufacturers. According to the infographic published by Samsung, the short circuits within the faulty batteries occurred when the separators allowing the positive and negative electrodes to meet within the jellyroll. Some batteries were also discovered to miss the insulation tape that should have been located between the negative and positive electrodes.

The faults discovered in the batteries supplied by SDI were apparently cause by Samsung's own division in charge of batteries moving to a whole new battery design and mass-producing it without properly testing it. On the other hand, ATL was apparently forced to make a lot of batteries very fast after the first recall, so they ended up with the missing insulation tape problems.

All in all, Samsung needs to slow things down a bit, and the delay of the upcoming Samsung Galaxy S8 might not be a bad thing in the long run. After all, what consumers need are reliable products that are also fast, not fast ones that might be reliable.

In my early school days, I hated writing and having to make up stories. A decade later, I started to enjoy it. Since then, I published a few offline articles and then I moved to the online space, where I contributed to major websites that are still present online as of 2021 such as Softpedia, Brothersoft, Download3000, but I also wrote for multiple blogs that have disappeared over the years. I've been riding with the Notebookcheck crew since 2013 and I am not planning to leave it anytime soon. In love with good mechanical keyboards, vinyl and tape sound, but also smartphones, streaming services, and digital art.
