Micah LeeI just set up a new public Signal number on this old cheap Android phone that has a battery that's ballooning out so much the case doesn't really fit on it 
Zack Beasley@micahflee Time for a new phone! I had that happen a few times with an iPhone. It started heating up and was losing charging capabilities. I went to a cellular dealer and replaced the phone. He told me I was lucky it didn’t catch fire. It can happen.
A neighbors iPhone was left laying on a bed while they were out and caught the house on fire! Fire Department traced it to the charging cell phone left on the bed!
