Hi! I understand your Jigsaw Master game opens to a black screen and then kicks you back to your lock screen on your Android 10 device. Let’s work through this together.

First, to get a clearer picture—did this problem start recently after an update or a change? Also, have you tried basic steps like restarting your phone or reinstalling the game?

Assuming you haven’t tried some of these yet, here’s a step-by-step approach:

1. Restart Your Device: This clears temporary memory issues that might cause crashes or black screens.

2. Clear App Cache and Data:
- Go to your Settings > Apps > find Jigsaw Master.
- Tap Storage.
- Choose Clear Cache, then Clear Data.
This clears temporary files and might fix corrupted data.

3. Update the Game and Android OS:
- Check Google Play Store for any updates to Jigsaw Master.
- Go to Settings > System > System update to ensure your Android 10 is up to date.

4. Reinstall the App:
- Uninstall Jigsaw Master completely.
- Restart your phone.
- Download it fresh from the Play Store.

5. Check Permissions:
- Jigsaw Master may require permissions to run properly.
- Go to Settings > Apps > Jigsaw Master > Permissions.
- Ensure all necessary permissions are enabled.

6. Free Up Storage Space:
- Insufficient storage sometimes causes apps to fail on launch.
- Check your available storage under Settings > Storage.
- Delete unnecessary files or apps if space is low.

If after all that, it still goes to a black screen and returns to the lock screen, it could be an issue with how the game interacts with your device’s graphics or software environment.

In that case, if you’d like, I can look up advanced fixes or official support contacts for you to get further assistance.

Would you like to try these steps first? Also, please let me know if you’ve tried anything already.
