Symptoms
- Icon opens to black frame
- Audio may play while screen stays blank
- App closes after a black screen
Likely causes
- Corrupt cache after a failed update
- Insufficient free RAM on budget phones
- Broken overlay (filter apps, recorders)
- Incomplete asset download on first run
Fix steps
- Force stop the app, clear cache (not necessarily data), relaunch on Wi-Fi.
- Reboot the phone and close heavy apps.
- Disable screen recorders / blue-light overlays temporarily.
- Reinstall the latest APK if cache clear fails.
Prevention
- Finish first launch on stable Wi-Fi
- Update instead of stacking broken partial installs
Black screens are often cache or overlay issues. Clear cache before wiping account data.
