Welcome to Android Central! System apps can show up as having activity when you don’t use them for various reasons — it doesn’t mean you’ve been hacked. How do you know you had apps install in the middle of the night and then uninstall afterwards — is there a log of that?
Assuming you’re not installing shady apps from shady websites, or indiscriminately tapping on links that pop up if you visit a shady website, and assuming you’re following basic security guidelines about keeping your login passwords private, it’s very difficult to be hacked.
