Hi there! I understand that StayFree isn’t blocking apps on your Galaxy S10e as expected. Let’s work through this together to get app blocking working properly.

First, just to make sure I understand:
- Are you able to open StayFree and see your blocked apps listed?
- Does the app appear to track your usage but just not enforce the blocks?
- Have you noticed any specific error messages or unusual behavior when you try to block an app?

This info will help me guide you better. Meanwhile, here’s a common checklist that often resolves such issues on Android 12 devices like yours:

1. Check App Permissions:
Go to Settings > Apps (or App Management) > StayFree.
- Tap Permissions and make sure it has all the necessary permissions, especially Usage Access and Accessibility, which are critical for blocking apps.
- If any permission is off, turn it on.

2. Battery Optimization Settings:
Battery optimizations can stop StayFree from running in the background.
- In Settings > Apps > StayFree > Battery or Battery Usage, look for “Optimize battery usage.”
- Set StayFree to “Not optimized” or “Unrestricted” so it keeps working even when the screen is off.

3. Enable Accessibility Service:
StayFree needs Accessibility Access to effectively block other apps.
- Go to Settings > Accessibility > Find StayFree and make sure it is enabled.

4. Reboot Your Phone:
Sometimes a simple restart helps apply new permissions or changes fully.

5. Update StayFree:
Ensure you have the latest StayFree version from the Play Store as updates often fix bugs related to blocking on recent Android versions.

If after these steps StayFree still doesn’t block apps, we can look into more advanced settings or verify if any device-specific security settings on the Galaxy S10e might interfere.

Have you tried any of these steps already? That way I won’t repeat but guide you further if needed!
