Exploding Note 7s – Samsung Disclosure of the Causes

Samsung’s Disclosure of Note 7 Explosion Issues


The Galaxy Note 7, a smartphone by Samsung, received huge press and the story we all know by now. Just in case you missed it the phone was recalled Sept 2nd which was only 2 weeks after it release.  By the second week in October, the phone was discontinued following reports of the phone exploding even after replacements were sent out. The issue continued with the replacements… crazy right?

Despite the issues the phone still received good reviews as being the better phone, minus the explosion problem. So millions of phone were sold (about 3 million) and still today there are people holding onto the phone. All this after a large scale recall campaign led by Samsung, mobile carriers, and retailers.

Apparently, Samsung has disclosed the results of an intensive investigation that points to the issue as being a battery defect which led to the heat failure of their Galaxy Note 7s. In the investigation Samsung ruled out numerous causes like Fast Charging, Wireless Charging, tightness of the phone’s design, the Iris Scanner, the USB Type C port, software, and the manufacturing process. Samsung performed their own investigation and enlisted the help of the 3 firms: Exponent, UL, and TUV Rheinland. The final results being the same among all investigation and research performed.

I was curious who the battery suppliers were since Samsung only referred to them as Company A and Company B cause without that detail in my book Samsung is just saying anything. Company A was the initial company used while Company B was used during the recall in an effort to rectify the problem. Now I could get into details of the investigation but that would lose most people who probably would not know what hell was being said (or read).  I am including a gallery of images to help some sort of visualize the problem but the images themselves are still not the easiest to understand without knowledge of how batteries work.



Explaining the Note 7’s battery flaws (with cake)

Like I said earlier I needed to know who these companies are so I went digging and could only find them as being Samsung SDI (Company A) and Amperex Technology. So if this is correct then Samsung technically made the batteries while they went to Amperex after the recall again to fix the problem. After looking over the details it seems everything just went wrong in this whole ordeal or it just feels that way by Samsung. So when Samsung release the Note 7 the batteries they made had defects so they recalled the phone and used Amperex batteries in the recalled models only to still find out that these batteries also had defects. So in Samsung’s haste to fix the issue they only created a reoccurring problem but for different reasons while simply said is the same issue. Question……   Anyone ever cross the negative (Black) and positive (Red) terminals on your car battery while trying to give someone a jump? What happens?

⇐ You can also watch the video by CNET to get an idea of what is being said in this post here.

Well this is what simply happened in both company’s batteries. The design of the batteries did not ensure enough that the positive and negative tabs stayed separated and the flaws found allowed the tabs to touch in both batteries. To make it worse the second company’s batteries, by Amperex, some of the them had no insulator (separator) at all in between the tabs.

Well it seems believable giving how much trouble Samsung went through to find the cause of the Exploding Notes. From all of the stories I have read about the damages to cars, homes, and bodily injury that this has to probably be the most expensive recall made. It took time but we all know how it is when dealing with such or similar matters, or even any matter at all when more than one person or group is involved. Always full of red tape, excuses, and is time consuming. All of this in an effort to save face through the use of transparency.

Samsung also has new policies and procedures being put into place to make sure this never happens again. They talked about improved quality assurance, safety processes, multi-layered safety measures, an 8-point battery safety check, and actually forming a group to oversee all of it. A Battery Advisory Group of sorts. So with all this talk Samsung is showing seriousness in gaining consumer trust and with the Galaxy S8 coming soon, let’s hope it all can be toss to the side along with with myriad of memes out there that this EXPLODING NOTE started.

It should be all over right? Let us know what you think?
