Seeing strange lines on your phone screen? Vertical or horizontal lines can appear suddenly and ruin your viewing experience. Here's what causes them and how to fix the issue.

 

 Common Causes of Screen Lines

1. Physical Damage (Drops or Pressure)

What Happens? If you dropped your phone or pressed it too hard, the LCD/LED panel or its connections may be damaged.

Symptoms:

Lines appear after impact

May worsen over time

Touch response may also fail

 

2. Loose or Damaged Display Cable

What Happens? The flex cable connecting the screen to the motherboard can get loose or damaged.

Symptoms:

Lines flicker or come and go

May temporarily disappear when pressing the screen

 

3. Software/Driver Glitch

What Happens? A system bug or faulty graphics driver can cause display errors.

Symptoms:

Lines appear suddenly

May change or disappear after restart

 

4. Water or Moisture Damage

What Happens? Liquid can corrode internal circuits, causing display issues.

Symptoms:

Lines appear after exposure to water

May be accompanied by discoloration

 

5. Manufacturing Defect (Rare)

What Happens? Some phones have faulty screens from production.

Symptoms:

Lines appear early in the phone's life

No prior damage or drops

 

How to Fix It?

1. Restart Your Phone

A simple reboot can fix temporary software glitches.

 

2. Check for Software Updates

Go to Settings > System > Software Update to ensure your OS is bug-free.

 

3. Test in Safe Mode (Android Only)

Boot in Safe Mode to check if a third-party app is causing the issue.

 

4. Gently Press Around the Screen Edges

If the lines change or disappear when pressed, it's likely a loose cable.

 

5. Backup & Factory Reset (Last Resort)

If software-related, resetting may help (backup first!).

 

6. Visit a Repair Shop

If lines persist, the screen or internal connections may need repair.

 

⚠️ When to Worry?

Lines spread or multiply → Hardware failure

Touch stops working → Urgent repair needed

Screen flickers or discolors → Possible motherboard issue
