Recently, a so-called “hack” went viral online — using a lighter flame to make the white lines on a phone display disappear.
⚠️ In reality, this is just a dangerous illusion that can cause permanent damage.
Why You Should Never Burn Your Phone Screen
- Why flame makes lines disappear
- Heat causes thermal expansion/contraction, temporarily restoring connection.
- Liquid crystal / OLED materials rearrange under heat → lines seem gone.
- After cooling, the issue comes back → fake repair.
- Real causes of white lines
- Loose flex cables
- Faulty display driver IC
- Damaged pixel/lines
All are hardware issues, they won’t fix themselves.
- Risks of high temperature
- Screen cracking
- Polarizer turning yellow, touch failure
- OLED burn-in → permanent black spots
- Logic board components damaged
These are far worse than one line.
Correct Troubleshooting Steps
- Software check
Restart / take a screenshot → if lines appear in screenshot → software/GPU issue. - External inspection
Check for drops or water damage
Press screen edge lightly → if lines flicker → flex issue - Hardware check
Reseat display cables
Reflow or replace IC
Damaged panel → requires Phone display assembly replacement - Special cases
Moving lines → GPU/driver issue
Fixed lines → screen damage → cell phone display screen replacement required
