- Physical Damage: Inspect the flex cable for any visible tears, bends, or damage that might have occurred during installation. If damage is present, the cable may need to be replaced.
- Software Issues: Ensure your phone's software is up to date. In rare cases, software glitches can affect hardware functionality.
If troubleshooting does not resolve the issue, it is highly recommended to consult a professional repair technician for diagnosis and repair.
