Exploding Galaxy Note 7s

Samsung's Galaxy Note 7 entered the market with a bang!
Literally. Some of the phones had actually exploded.
The world's largest maker of mobile phones had to recall 2.5 million units of this particular model – and all because its batteries began catching fire while charging.
The recall already puts fresh pressure on Samsung, which is already squeezed by competition from Apple in the high-end market and Chinese rivals in the low-and mid-end segment.
And it didn't take the Internet long to come up with all sorts of hilarious responses – a couple of my favorites have been included here. Just be careful… you might just explode with laughter!

Actually, no brand or model is necessarily safe.
That is because phones use lithium ion battery packs for their power, and it just so happens that the liquid swimming around inside most lithium ion batteries is highly flammable.
If the battery short-circuits – say, by puncturing the incredibly thin sheet of plastic separating the positive and negative sides of the battery – the puncture point becomes the path of least resistance for electricity to flow. It heats up the (flammable!) liquid electrolyte at that spot. And if the liquid heats up quickly enough, the battery can explode.
It is not as if Samsung or any other phone manufacturer doesn’t know that lithium ion batteries pose a risk – but the electronics industry continues to use the flammable formula because the batteries are so much smaller and lighter than less-destructive chemistries. Lithium ion batteries pack a punch, for better or for worse.
Anyway, according to an unnamed Samsung official who spoke to Yonhap News, the Note 7's manufacturing defect affects less than 0.01 percent of all Note 7 handsets sold.
Some quick back-of-the-envelope math, and you're potentially looking at fewer than 1,000 defective phones. "It is a very rare manufacturing process error," a Samsung rep told CNET.
