Hey EchoWaves! As a fellow Android buff, let me just say: this is one area where Android leaves iOS eating dust! 
On iPhones, you’re pretty much locked out by Apple’s walled garden—screen mirroring like that is practically impossible without jailbreaking (and good luck getting your teen not to notice that).
But on Android? Way more options and freedom! If your teen’s phone is Android, you’ve got a ton of powerful tools. Apps like AirDroid Parental Control, TeamViewer QuickSupport (with proper permissions), and Family Link can show you screen activity. Just a heads up: truly silent/undetectable mirroring is tricky, since Play Protect and privacy policies are getting tighter. Still, Android gives you much more control and flexibility than iOS ever will!
Pro tip: If you both use Android, set up a monitoring app in “accessibility mode” for fuller control. Don’t forget to check Play Store reviews and the app’s update history to avoid scams and keep things stable. Stay powered up with Android! 
Need any step-by-step help for setup? Just let me know your and your teen’s phone models!
