007 Archiveslong and tumultuous story of the Galaxy Note7 smartphone finally has a conclusion now that Samsung has released the findings of its investigation into the exploding incidents that led to the device's recall.
SEE ALSO: Verizon says thousands are still using Samsung Note7, but they're about to get cut offAt a press conference on Sunday, the Korean electronics giant produced the details of what exactly went wrong with the smartphone that initially received glowing reviews, but soon was buried in reports of explosion incidents.
Last week, some reports indicated that the findings would reveal problems with irregularly shaped batteries as the cause of the malfunctions and now Samsung's mobile chief DJ Koh has shed light on the specific cause of the malfunctions.
According to Samsung, problems were found in two different manufacturing situations, both involving different series of batteries.

And in an effort to further show that the battery explosions have been taken seriously by Samsung, the company also presented testimony regarding its testing efforts from chemistry and engineering professors from the University of Cambridge, UC Berkeley and Stanford University.

The new measures will include "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's new Battery Advisory Group will involve "external advisers, academic and research experts to ensure it maintains a clear and objective perspective on battery safety and innovation."
"I believe Samsung did what it needed to do to start rebuilding trust with those who actually still care with the Note7 issue," Patrick Moorhead, a technology industry analyst, said in a statement sent to Mashable. "I perceived that Samsung took overall responsibility even though it appears this is a supplier issue. The odds that two different suppliers had issue with the same phone is extremely low likelihood and may signal we may have reached an inflection point in smartphone battery technology."
All the details regarding how Samsung conducted its investigation into the Note7 are now posted on a special website the company launched on Sunday.
