I've had my samsung coming up to 2 years, in very good condition, kept in case, hardly ever drop, never got wet/drop in water. All of a sudden today the phone shuts down x3 and restarted. Did a diagnosis run everything is fine, suddenly phone starts to crackle loudly, bottom half of screen went and it shuts down again and just left side of phone become hot. I thought it was going to explode Anyone else having this issue?
