Possible causes:
- Software: Glitches, outdated apps/OS, conflicting settings like auto-brightness or blue light filters.
- Hardware: Physical damage like cracks, water exposure, or faulty internal components.
Troubleshooting steps:
- Quick fix: Restart your phone. Often a temporary glitch is the culprit.
- Software checks:
- Updates: Ensure your OS and apps are updated. Bugs might already have fixed.
- Settings: Disable auto-brightness and blue light filters. Play with brightness levels.
- Safe mode: Boot into safe mode (instructions vary by phone model) to see if it's app-related. Uninstall suspicious apps.
- Hardware checks:
- Damage: Inspect for cracks, scratches, or water damage. Contact your phone manufacturer or a trusted repair shop.
- Charging: Try a different cable and power outlet. Faulty connections can cause flickering.
If all else fails:
- Backup & reset: Backing up your data first, try a factory reset. This wipes everything clean and resolves software issues.
- Contact support: If nothing works, reach out to your phone manufacturer's support team for further diagnosis and repair options.
