Puffy LiPo LG Cell Phone battery, super dangerous possible explosion and burn down house Stylo 4 5 6

Lithium polymer always make me nervous. I've seen them explode before and its not pretty. I was replacing the screen on my kids cell phone on his LG Stylo 4 when I noticed the back of the battery cover was being pulled off my an expanding battery. These batteries can basically turn into a thermite grenade or explode. This is the first time I have every seen a cell phone battery do this. I've seen it in RC batteries because of rapid charging.
