Hi there! I see you’re getting a black screen when trying to register in the Castle Crush app on your Android device. I’d love to help you get this sorted out. Could you tell me a bit more? For example, does the app show the black screen immediately after you open it for registration, or does it happen sometime after you enter your details? Also, have you tried any steps already like restarting the app or the device?

Meanwhile, I can suggest a few common fixes that often resolve black screen issues in Castle Crush on Android 10:

1. Restart the Device
Sometimes a fresh start clears minor glitches.

2. Clear Cache and Data for the App
- Go to your device Settings > Apps > find Castle Crush.
- Tap Storage > then select Clear Cache.
- If that doesn’t help, try Clear Data (note this might reset app settings, but your account progress shouldn’t be lost if it’s linked online).

3. Check for App Updates
Ensure you have the latest version of Castle Crush installed from the Google Play Store, as updates often fix bugs causing black screens.

4. Check Network Connection
A poor internet connection can sometimes cause the screen not to load properly. Try switching between Wi-Fi and mobile data to see if it helps.

5. Reinstall the App
If none of the above work, uninstall the app fully and reinstall it.

If you’ve tried some of these already or the problem continues, please let me know. There might be a more specific issue we can troubleshoot further.
