1. Update Filmora to the latest version via the Google Play Store or Apple App Store.
2. Ensure no video clips are selected, then re-apply the effect by navigating to 'Effect' and searching for 'Mosaic'.
3. Test other effects to determine if the issue is specific to the Mosaic feature or a general preview problem.
4. Restart the application and attempt the process within a new project.
If the issue persists, please submit a report via Mine > Feedback. Include screenshots, screen recordings of the issue, and log files to assist our technical team with troubleshooting.
What should I do if the Mosaic feature is not working in Filmora mobile?
