Tell that to the people that lost money on this whole fiasco. Not everyone came out whole or a little better..
If I were a stockholder, I'd be upset, sure. And, I'd definitely be upset as an employee (a number of which are going to lose their jobs in the wake of this, I'm certain). As unfortunate as that is, I just don't see this as a willfully negligent situation.
I have a hard time believing this is anything other than a smallish engineering mistake that appeared to be solved, and then wasn't. I've owned LOTS of Samsung phones (right back to the SPH-I300 PalmOS based unit), and never got the impression that their production was anything short of decent. Build quality was always quite good, and software implementations were always as good as they could be given the limitations of the time.
Let me lay out a possible scenario for you: I don't know what actually went down, but I suspect (a Guess, people, and nothing more) that it really was something like this... Source: The problem exists in the combination of attachment method of the battery and an over-agressive implementation of the charging controller. Symptom 1: Statistics show that virtually all of the fires are occuring in serial numbers that use batteries from supplier A. This is determined to be the common denominator, and all implementations from supplier A are recalled and replaced with units from supplier B. Subsequently, we see Symptom 2: Replacement phones are catching fire (though at a greatly reduced rate) anyway. Conjecture 1: The problem is in the charging or battery management components, and battery supplier A's product happens to be more susceptible to the issue, leading to the mistaken conclusion that the batteries themselves were the issue. However, once replaced, the real issue rears its head, and continues to be problematic for the consumer.
In this case, Samsung simply reacted too quickly to fix a problem that it perceived as truly serious by going down a path that appeared to contain the solution. Once they determined that their solution was not the correct one (which, unfortunately was only ferreted out by the distribution to an unfortunate test group of several hundred thousand consumers), they simply pulled the phone and are actively participating in it's aggressive phase-out from the user community.
Frankly, I don't see how they could have done things better in the timeframe that the consumer demands. (Make no mistake, consumers DEFINITELY demanded the phone be fixed and replaced IMMEDIATELY, giving no slack for Samsung to properly pursue the engineering problem. If you don't think so, just reread some of the off-the-deep-end "Samsung Should's" in these forums alone! We are not terribly forgiving people in this way.)
