I would not be rushing out any new phones until a full account of the Note 7 disaster has been transparently revealed. Samsung needs to build consumer confidence. Samsung's handling of the recall, return and then ultimate end of the Note 7 raises many questions about the company. That handling could impact all of Samsung's product lines in the home. That is what the market is screaming today with a multi-billion dollar loss to Samsung Electronics' share price.
No need to panic just yet at Samsung. Toyota (faulty pedals), Takata (air bags), Merck (Vioxx), Johnson & Johnson (Tylenol) and many other companies have all had massive product recalls and recovered. The fact that the Galaxy Note 7's product cycle went a bit more than 7 weeks indicates that the damage could be limited.
So for the rational person, the damage can and should be able to be contained. But consumers buy things for all sorts of irrational reasons. And they avoid buying things for equally crazy reasons. Expect jokes to abound about Samsung batteries in future.
Samsung's reputation as an engineering and device innovator is hit. Samsung rushed the Note 7 out too quickly. Rushing out the S8 to try to wipe the slate clean could also have negative consequences. Samsung needs to publish a full account of what went wrong and how they plan to fix it.
Meanwhile Google will become a high end device hardware company. The Pixel is a safe, high end choice with plenty of innovation, esp in software.
Rushing out the S8, perhaps even a foldable device, might have seemed a great idea last month. Today not so much.
