The main reasons a phone screen keeps going black are software glitches, display connection issues, overheating, battery or charging problems, physical damage, or malware infections. Common causes include:
- Software bugs or glitches, especially after updates or installing incompatible apps.
- Loose or damaged internal connections between the phone and its display, often from drops or physical impact.
- Overheating causing the phone to shut down or freeze.
- Battery problems such as depletion or faulty chargers.
- Malware or viruses causing system disruption.
To fix it, typical steps are:
- Force restart the phone to clear software glitches.
- Charge the phone fully and check the battery health.
- Gently press or squeeze the phone to reconnect any loose display components.
- Remove and reinsert battery, SIM, and SD cards if removable.
- Clean charging port and check for stuck buttons.
- Boot in safe mode to identify problematic third-party apps.
- Clear cache or perform a factory reset as last resort.
If these troubleshooting steps don't work, the black screen may indicate hardware failure requiring professional repair.
