In one of my posts (["get it repaired" vs. "repair it"](https://ell.stackexchange.com/q/240578/109190)) I said

Actually, what I suffered is that my phone repeatedly restart by itself.

Is it appropriate to describe that problem as "**broken**"?

Or, only the following status is called "**broken**". If it is, is "repeatedly restart by itself" called "does not work" or "is not working"?
