Samsung will survive
Nowadays consumers have very short memories.
I realise that products exploding, destroying property and burning folk is a very bad thing indeed, but if Samsung drop the Galaxy and Note brands - both of which were getting very dated - and come up with something equally daft, but new and brighter, people will still flock to purchase the new shiny in vast numbers. In fact Governments rely on their citizens so doing, because a happy consumer is always more pliable than a cautious saver. Right? Right.
As Conrad Longmore writes above, the iPhone 'Antennagate' debacle - a phone that would only phone if you didn't touch it - hasn't stopped Apple one bit. Quite the opposite: it just legitimised cases, so driving sales of accessories through the roof. Steve Jobs must've been wetting himself.
It's almost at the stage that Samsung could capitalise on this and run a marketing campaign: "Samsung, because everyone deserves a surprise tan, whatever the weather" - it'd simply go 'viral' (whatever that really means), the Daily Mail would run a campaign giving away a free Samsung phone 'to every migrant in your area' and the money would keep flowing.
