It’s officially official. Samsung has released its analysis and conclusion regarding the Galaxy Note 7 fiasco.
A major press conference was held yesterday featuring independent researchers Sajeev Jesudas, President, Consumer Business Unit, UL, Kevin White, Ph.D, Principal Scientist, Exponent, and Holger Kunz, Executive Vice President Products, TUV Rheinland AG.
After testing 200,000 Galaxy Note 7 devices and 30,000 batteries (for the Note 7), it was discovered that both the original batch of phones and replacement devices featured separate design defects, resulting from haste in trying to ramp up production to counter lost sales.
Samsung released an infographic, concluding that all issues stemmed from various faults surrounding the battery, and not the rest of the device.
Battery A (the battery used in original Note 7s) featured a negative electrode that was bent in the top right hand corner (pictured below), resulting in potential combustion. It was determined that the electrodes ended up bending as a result of the battery being too big for the pouch it was fitted in.
Battery B (used in replacement devices) corrected the negative electrode issue. However, high welding burrs on the positive electrode in the manufacture stage punctured insulating tape, resulting in direct contact with the negative electrode. This contact would also have resulting in combustion. They found that many of the tested batteries were missing the insulation tape entirely.
Now that Samsung has sorted out its problems, they also outlined a series of measures to be used in the future to avoid problems like this.
Let’s hope that they get it right this time, especially given the fact that they are set to release their upcoming Galaxy S8 in a few weeks time.
Can Samsung recover from this fiasco?
It is going to take some time, and there is even more pressure on them to be thorough, as another incident like this could spell the end of their mobile division, and potentially harm the brand on the whole.
