Samsung has released its official report on why the batteries in the Galaxy Note 7 smartphone were exploding. Notably, the issues differed between the original battery and the replacement battery used after the first recall.

“For the last several months, together with independent industry expert organizations, we conducted thorough investigation to find cause to the Galaxy Note7 incidents,” DJ Koh, President of Mobile Communications Business said. “Today, more than ever, we are committed to earning the trust of our customers through innovation that redefines what is possible in safety, and as a gateway to unlimited possibilities and incredible new experiences.”

Based on what the company learned from the investigation, Samsung implemented a broad range of internal quality and safety processes to further enhance product safety including additional protocols such as the multi-layer safety measures and 8-Point Battery Safety Check. Samsung also formed a Battery Advisory Group of external advisers, academic and research experts to ensure it maintains a clear and objective perspective on battery safety and innovation.

Here are some of the main issues uncovered by the investigation:

Root Cause: Manufacturer A
Based on the results of analysis and testing, the most likely root cause for the thermal failure of certain Manufacturer A cells was determined to be unintended damage to the negative electrode windings consistently in the corner of the cell closest to the negative tab

Root Cause: Manufacturer B
Based on the results of analysis and testing, the most likely root cause for the thermal failure of Manufacturer B cells was determined to be internal cell faulting between positive electrode tab welding defects and the copper foil of the negative electrode directly opposite the defective welds

I knew Samsung wouldn't own up to the real issue with their phone and instead would blame the battery manufacturer. If it was really a battery issue, it wouldn't have happened with 2 separate suppliers and they wouldn't have recalled all the phones, they would have just fixed the battery and continued selling the devices. Samsung is making phones explode, Washing machines explode, hopefully people don't have their Samsung fridges explode. It's funny how you call Apple fans sheep, when it's obvious who the real sheep are... why would anyone buy a product off a company that copies others, put other good businesses out of business by stealing their copyrights and keeping them tied up in courts until the company can't afford it any longer and end up going out of business. You think people would educate themselves before supporting such an evil company. I don't have anything against their products but I would never buy from a company that is run like this.

Don't forget the political scandal that Samsung is in with the impeached Korean President.

Surely this is not the first battery they've got from these two manufacturers. How's that it's only happening to the note 7. The common denominator here is the note 7. They just can't admit a design flaw in the Note 7!

If this could happen to Samsung, then it could happen Apple, HTC, LG. Who is the battery supplier?
