    We finally know what was wrong with the Galaxy Note 7

    Samsung has officially released its findings as to what was the underlying fault with the canceled Galaxy Note 7.

    Samsung’s ill-fated Galaxy Note 7 might well go down in the history of consumer electronics as an unfortunate victim of progress. The smartphone, which was hailed in early reviews as the best device Samsung had ever produced, might well have taken the top honours in our Bandwidth Blog Awards had it not gone supernova in its users’ pockets.Bandwidth Blog Awards

    Samsung has revealed that the cause of explosions – which not only totaled the device but in some cases properties and vehicles around it – was instigated by two distinct battery flaws and not a software issue.

    Samsung has detailed that the first flaw was in the construction of the Note 7’s internal battery; the company revealed that the casings were too small to safely install the electrode assembly inside and subsequently the battery short-circuited.

    Samsung cites that in some models “the damage was caused by a cell pouch design that provided inadequate volume to accommodate the electrode assembly.”

    Samsung outsourced the production of the battery to two different suppliers; while variants produced by ‘Manufacturer A’ were faulty, those produced by the remaining manufacturer did not suffer from any of those mentioned design deficiencies.

    Instead, when reports began that Galaxy Note 7 were exploding in their user’s hands, Samsung immediately launched a worldwide recall and issued new ‘safe’ devices. In the process, the company inadvertently created another massive design flaw.

    Samsung revealed that batteries provided from ‘Manufacturer B’ introduced a welding defect that made ‘safe’ replacement models prone to bursting into flames in the same manner as the predecessor.

    This time around, Samsung has offered that the internal cell that separated the positive and negative tab of the battery were prone to welding defects, and some were even produced without protective tape over the positive electrode tab.

    The company clarified that both the positive and negative ends of the battery could have come into contact on certain models, generating excessive heat and energy that could have caused an explosion.

    Samsung Electronics America President Tim Baxter offered the company’s belief that if were “not for that manufacturing issue on the ramp (of the replacement battery), the Note 7 would still be on the market”

    Samsung Mobile head DJ Koh ‘deeply’ apologized to customers for the company’s failures, and clarified that the Galaxy Note 7’s devices wired and wireless charging, USB Type-C port, or Iris scanning feature were not in any way linked to combustions.

    Koh cited that Samsung had enacted a number of internal changes to its processes to avoid repeating the same mistakes, and has shared an advertising blitz stating its renewed commitment to quality.

    The company is placing all its bets on the forthcoming Galaxy S8, which will reportedly introduce a number of new features such as a near-bezeless design, an AI assistant, and several of the UI enhancements that were found on the Note 7.
