My Galaxy Note 7 exploded (sorta). I got it replaced free of charge with a new phone of a different type, but I didn't really like it so I gave it to my mom and swapped it out for her S5 which I still use.
It was just charging one night and I woke up to a really loud popping/crackling noise. I turned on the light and my phone smelled burnt and smokey. The bottom end of the phone had melted and it wouldn't turn on. It had also melted on the charging port and I couldn't remove the charger. Fun story to tell whenever people brought up the exploding Note 7s.
