When a pillow catches fire

My previous phone. Happened about 10 months ago and found it in my camera roll so I decided to post it here. Phones a Motorola I believe. Happened at night and woke up to my phone smoking like crazy. Grabbed it and threw it outside before it could get worse. I don't believe it even actually got engulfed in flames considering how the damage is but I know it was completely fried and I couldn't even get the sim card out of it. I believe the outer frame around the screen is metal and it got warped from the heat. I still have the phone somewhere tho id need to search for it. Was gonna claim warranty on it but I couldn't even reach them so I just got another Motorola phone. Luckily my current one hasn't caught fire yet. I believe it was only 5 or 6 months old when the battery failed and caused this. Must've been a defect or something.
