Samsung finds two reasons to blame for Galaxy Note 7 exploding batteries

Samsung will officially announce the reason for the Galaxy Note 7 recall on Tuesday, but an early report by the Wall Street Journal sheds light on what's to blame even before the event.

The main reason behind the recall seems to be indeed irregularly sized batteries that caused the phone to overheat. However, that was not the only reason, and other Galaxy Note 7 had batteries that were manufactured defectively.

The Galaxy Note 7 went on sale in August 2016 and carried batteries manufactured by either Samsung SDI or Amperex Technology, a Hong Kong company that makes the batteries at a factory in China. At first, the company thought only the Samsung SDI-made batteries were defective and acted quickly to recall those units, but the following ramp-up of production at Amperex resulted in faulty manufacturing and problems arose again, causing the full recall.

The official report will go on more detail and explain in its entirety the reason behind the recall of 2.5 million Galaxy Note 7 phones that cost the company at least $5 billion.

Samsung has taken the investigation seriously, hiring three independent contractors to investigate reasons in quality control and the supply chain. 

In addition, Samsung officials have met with U.S. Government representative in Washington DC to present the report and the officials are allegedly happy with the investigation that has been carried out. The company has also laid out an 8-step plan including more testing, inspections and manufacturing quality assurance to ensure that the issue won't happen again.

Meanwhile, Samsung has also said that 96% of all Galaxy Note 7 have been returned by users. Airlines have banned the use of the phone on board, and were required to announce the ban until recently.

This is the problem that people wrongly attribute to any product that is recalled: just because a product is recalled does not necessarily mean that all products are going to demonstrate that same problem. The purpose of a recall is to PREVENT there ever being a possibility that a known safety issue ever does occur. The biggest example of this is car recalls. Every year, auto manufacturers recall thousands of car models for a certain problem that was found to be in a sample size (sometimes it can be as little as 30 cars with a problem to the hundreds). Remember the Toyota/Lexus floor mat acceleration issue? Not everyone experienced the issue (in fact the overwhelming majority DIDN'T), but because there was a select number that did they recalled every car to ensure that it met new safety standards. So, to answer your question, your phone COULD be perfectly fine, but because there was a problem found in a good amount of devices they have decided to recall the phone to PREVENT the possibility of future problems. TL;DR: Recalls are for PREVENTION purposes, it does NOT mean that ALL devices will showcase a particular issue.

Samsung is just in denial about their lack of QC. They should be embarrassed over the entire Note 7 debacle.

You're an idiot. Samsung makes 50 phone models at the least. If Samsung had bad QC like you claim, explain how they only have a 7% failure rate which it was the S6, while company's who make half as many phones like Apple, has a 25% failure rate on a single model. You are just stupid. But hey, you're not alone in your stupid little basement world.
