For the core Samsung fans, this will end up being extremely beneficial, assuming Samsung Electronics is able to weather the massive sales numbers drop over the coming year or two.
First, the future Samsung models will be meticulously tested and carefully rolled out (so they don't go through the same thing again). More importantly, they will have to be significantly cheaper than before (and than the competition), in order to convince ordinary people who now know, from the news they read, that Samsung phones explode.
This debacle will inflict long-term damage to the Samsung mobile brand. When you tell an ordinary person "Samsung Note 7", all they hear is "Samsung". For them, simple reasoning will be, when there are HTC, LG, Motorola (and, of course, Apple), why take a chance with Samsung when they explode?
Airport security staff will be trained to quickly identify Samsung Note 7 phones, in order to prevent people who choose to keep their Note 7 from boarding. It is quite possible that in that screening process, there will be plenty of "false positives" (when the screening agent flags another Samsung phone), causing possible argument, or even altercation with an innocent Samsung phone owner.
The brand is now seriously tainted, well beyond Note 7. And it will take years to repair.
