Possibly. Nothing comes close. Nokia and Sony Ericsson both once had to suspend sales of the N97 and Satio in 2009, if I remember correctly, but it was due to minor build issues, and there was the Nokia Battery recall for the BL-5C found in the N70, N91, E60 and some others, that could explode, but guess what? You could REMOVE those batteries, and it was barely a scratch on Nokia thanks to that.
Amazing that it took this long to happen, you barely ever heard of Nokia, Sony Ericsson, MOTOROLA etc... Phone batteries exploding back in the early 2000s.
I guess with these manufacturers trying to super slim these devices, make the more functional and more powerful it was bound to happen. I hope Samsung learnt a valuable lesson here, what a shame!
