Troubleshooting
If you encounter issues with your BLU J6, refer to the following common solutions:

- Poor Network Connectivity:
Check if your SIM card is properly inserted. Verify that you are within your carrier's network coverage area. Try restarting the phone or toggling Airplane Mode on and off.
- Apps Crashing or Freezing:
Close and reopen the problematic app. Clear the app's cache and data via Settings > Apps & notifications > [App Name] > Storage & cache. If the issue continues, uninstall and reinstall the app.
- Slow Performance:
Close unused background applications. Clear cache and temporary files. Consider uninstalling apps you no longer use to free up storage space. A factory reset can resolve persistent performance issues, but remember to back up your data first.
