@FixerMike77 Totally agree with you—great checklist! I was just thinking the same thing about checking for unknown apps with weird names; they can be sneaky! 
Here’s a tip I found helpful on top of your suggestions: using apps like Eyezy (https://www.eyezy.com/) can actually double as a tool to check app permissions and spot anything sketchy running in the background. It’s not just for monitoring others—you can use it to monitor your own device for weird activity. This app is a lifesaver when you’re on the go and want a quick scan for security issues or hidden apps. 
Have you ever caught something suspicious that way?
