What surprises me the most is that you read some of this posts and some people think that it's Samsung's fault because of lack of Quality Control, until Samsung announce that a WHOLE batch of batteries were damage then there is not too much a company can do.
Let me explain, when you mass product things, anything, is completely unrealistic to expect that every single or even half of their devices are tested for everything, I mean, they design the phone, the phone is tested for several months, every individual component of the phone is also tested but not every single one of those components are tested, there are random or measured spot checks for everything, displays, memory, cpu and even the battery, so assuming a WHOLE batch of batteries were damaged when Samsung received it, then it was just negligence on their part for not testing those batteries before using them for their products, and the probabilities of that is ZERO, a giant company like Samsung won't suffer from that negligence.
So, if you are with me until now, you'll understand that what I want to say is that it's obvious those batteries and a lot of others were damaged hence the recall, but as huge as this may seems to be, it can easily be just a batch, but that batch may have been of 1000 batteries and only 100 were damaged and if Samsung has a policy of random testing just 5 or 10 batteries per batch, then statistically speaking it is very possible (and just PURE BAD LUCK) that they did their part and what has always been a good testing policy, never spotted the bad ones.
It gets even more complicated and more difficult to spot when it's even 5 or 10 bad batteries for every 1000 batteries batch, and they discovered that were various batches with the issue, and that may easily be what happened here and the reason Samsung decided that was out of their control and that was easier to just do a recall. Even when you can test ALL your batteries, this batteries are not exploding the first time they are charged or used, certain conditions needs to occur for this to happen, so they may also do simple tests to the battery, it works great, they use it on the phone, and then a week later after some heavy use and other conditions, it triggers the defect and explode. Now that they know what was wrong they may look for it, but before this began, those same damaged batteries may have well been tested and appear to be fine. Do you get my point?
I'm not saying it wasn't Samsung's fault, of course it is, it's their brand on those phones and their responsibility for everything that can go wrong with it, it's just that people like me that has worked on big companies and Mass production lines, know that it's not as easy to spot this issues as some people are saying, insinuating that it was pure Negligence what has happened, THIS issue can easily happen again and to any other OEM and any device that use a Lithium Battery, just do a Google search so you can see previous instances of iPhones, Motorola and other OEM phones exploding and/or getting fire. The damage will be significant to the brand but nothing that can't be fixable, the key here is that Samsung has done or tried to do the best they could since even before this got out of control.
