Phone freezes and restarts

This hadn’t happened for a while, but has just started again. I thought it was Facebook, but I removed the app and it’s still happening with any app or none - usually after I’ve been using the phone for a little while (15 minutes?) but the phone isn’t hot (and sometimes it happens when im not using it).

Not sure if it’s since the latest update or had started before then.

Does anyone have any ideas? Bear in mind that I’m a technophobe/luddite so won’t understand any technical terms! Thanks!
