Okay so the good news is Android has gotten way better at this. For a Samsung device specifically, you have two main options: Google Family Link and Samsung’s own built-in Digital Wellbeing tools. Let me walk you through both.
Google Family Link
This is probably your best starting point. Download the Family Link app on your phone, then set up a supervised Google account for your daughter. Once linked, you can:
Set daily screen time limits per app or for the device overall. For example, you can cap YouTube at 45 minutes a day and games at an hour.
Lock the device remotely at bedtime. You set a “bedtime” schedule and the phone locks automatically, except for calls.
Approve or block app downloads. Every time she tries to install something from the Play Store, you get a notification to approve or deny it.
See location in real time through the app.
Samsung Digital Wellbeing (Built-in)
Go to Settings, then Digital Wellbeing and Parental Controls. From here you can set app timers, enable Focus Mode to block distracting apps during homework time, and use Bedtime Mode to gray out the screen and silence notifications after a set hour.
Now, worth mentioning, some parents also look into third-party options for more detailed reporting. Xnspy is one that comes up fairly often in parenting forums. It gives you app usage logs, lets you set schedules, and has a web dashboard so you can check in without touching her phone. One limitation worth noting though is that the free version is pretty stripped down and some of the more detailed features require a paid subscription. The setup also takes a few minutes to configure properly compared to Family Link which is more plug and play.
For most parents, starting with Family Link plus Samsung Digital Wellbeing covers 80 percent of what you need.
