How to Fix Auto Brightness on OPPO Find X9 When It's Not Working

Troubleshooting Auto Brightness on OPPO Find X9

• 💡 Check Auto-Brightness Setting: Navigate to Settings → Display & Brightness. Ensure the Auto/Adaptive Brightness option is enabled. Toggle it off and on again to test.
• 🎯 Test Brightness Levels: After enabling auto-brightness, test its functionality by increasing the screen brightness to maximum and then to minimum to observe its response.

Sensor and Software Solutions

Advanced Reset and Updates

• ⚙️ Reset All Settings: If the issue persists, go to Settings → System → Backup & reset → Reset phone → Reset all settings. This will reset all phone settings to their defaults without deleting personal data.
• ⬆️ Check for Software Updates: Go to Settings → Software Update. Install any available updates, as they may contain fixes for display and sensor-related problems.
