Hi there! I'm here to help you resolve the blank screen issue you're experiencing with the Quran 13 Line app. I can imagine it’s concerning when the app isn't displaying properly. Let's try a few steps to see if we can get it back up and running for you.

1. Restart the App: Sometimes, a quick restart can resolve temporary issues. Close the app completely and then reopen it.

2. Clear App Cache: Clearing the cache can often solve display issues. Here’s how you can do that:
- Go to your device's Settings.
- Tap on Apps or Application Manager.
- Find and tap on Quran 13 Line.
- Select Storage.
- Tap on Clear Cache.

3. Clear App Data: If clearing the cache doesn't resolve the issue, you might need to clear app data. Note that this may reset any preferences or downloaded content in the app.
- In the same menu as above, after selecting Storage, tap on Clear Data.

4. Reinstall the App: If the problem persists, uninstalling and then reinstalling the app could help.
- Long press the Quran 13 Line app icon and select Uninstall.
- Then, go to the Google Play Store, search for Quran 13 Line, and reinstall it.

5. Check for Software Updates: Sometimes these issues can result from being on an outdated version of the app or your device. Make sure you're running the latest version of both your app and Android OS.

Let me know how it goes after trying those steps. If the issue isn't resolved, we can look into more advanced troubleshooting together!
