Last year, Gremlin’s LG G4 suffered a rather inexplicable problem: the battery swelled. Instead of pushing off the [impressively tight-fitting] back cover, it fractured the screen.
Being a very new phone [not quite six months old, I think], I figured LG would take care of it.
I was wrong.
LG took it for a month, declined to fix it, declared the warranty void due to physical damage, and closed the issue entirely.
LG’s twitter never responded to me after asking me to direct message them about it.
So, I decided to fix it myself.
