Considering how easy it would be to turn batteries into time-fused bombs (that pass QA) with the tiniest of impurities in the manufacturing process, I sometimes wonder if the note 7 problems could be the visible part of Samsung trying to stand up to a protection racket. I guess it would not take that big of a network of infiltrators or blackmail-handles on factory floor workers distributed over a range of suppliers to go all "nice phones you have there, would be a shame if they burnt..." on a phone brand. The weak point of this theory is that the risk/cost of going public about this kind of threat would not be terribly high, unlike e.g. in plain old hostage taking.
