How anyone can say they did everything right is insane.

2. None of the phones "Exploded" they caught fire, big difference
3. What exactly do you believe they should have have done differently
I'll bet that if you do word associations with "Samsung phone" a lot of people will say "fire," "exploding" or something similar. Now if you were trying to create that association it would be great marketing, but I'm guessing Samsung's marketing department was going for a different association.

They were radio silent for MONTHS longer than they should have been. No "we're sorry", no "we're looking into it and will update you soon", nothing, for MONTHS.
