My phone is shutting off for no reason. WHY!?!?

[AC Question]

My phone restarts (like turn off and back on) all by itself I don't push the restart button or anything it might be in the middle of a phone call or in the middle of a game sometimes its when a game is loading for me to play on. What I want to know is why? Why is this happening to me and to my phone? Just... I mean I know that a lot of phones mess up and break but this was really expensive and me and my family are on the poor side we fully rely on foodstamps to by our cat food dog food and regular human food so we really can't buy me a new phone we can barely even afford food because the government gives out way to little food stamps s9 does anyone onow why this is happening to my phone if so then can you explain to me how to fix it if you can.

We'll certainly try. First, what is the phone, and did you buy it new?
