Common Causes of Horizontal Lines on Phone Screen

1. Physical Damage

A. Dropping Your Phone

One of the most prevalent reasons for horizontal lines on a phone screen is physical damage. This damage can often occur when the phone is dropped or subjected to pressure.

• Immediate Impact: When a phone falls, the impact can jar the internal components, including the display. Even if there are no visible cracks, internal parts may have shifted or been damaged.
• Subtle Microscopic Damage: Even minor drops can cause microscopic fractures in the screen’s internal structure, leading to display issues over time.

B. Cracks and Bumps

Sometimes, the impact may lead to visible signs of damage such as cracks or bumps.

• Surface Cracks: A hairline crack on the screen can disrupt the liquid crystal display, causing lines. Even if the crack is not immediately apparent, it can compromise the screen’s functionality.
• Internal Layer Damage: If the internal glass layers of the display are compromised, it may lead to artifacts like horizontal lines appearing intermittently or persistently.

2. Faulty Display Connection

Another common cause is a faulty display connection. This issue can stem from a loose or damaged cable that connects the display unit to the smartphone’s mainboard.

A. Loose Connectors

Over time, connectors between the display and mainboard can become loose due to wear and tear.

• Connector Issues: If connections are not securely in place, signals may not be relayed correctly, resulting in horizontal lines appearing. This situation often occurs after a device has been opened for repair or maintenance.

B. Defective Display Assembly

In some cases, the display assembly itself may contain defects introduced during manufacturing.

• Quality Control Oversight: If components are not adequately assembled during manufacturing, display defects may develop early in the phone’s lifecycle. Users may notice horizontal lines as a result.

3. Software Glitches

Sometimes, issues with the display are not due to hardware but rather software glitches.

A. Operating System Updates

Occasionally, software updates can introduce glitches that affect display performance.

• Incompatibility Issues: If a new update is incompatible with existing software or certain apps, users may encounter visual disturbances, including horizontal lines.
• Temporary Bugs: Following an update, it is not uncommon for bugs to temporarily cause issues with screen performance.

B. Third-Party Applications

Certain third-party applications may also interfere with your display.

• App Conflicts: If an app is poorly coded or incompatible with the phone’s system, it might lead to unexpected lines on the screen.

C. Virus or Malware

Sometimes, malicious software can disrupt normal phone operations.

• Malware Effects: A virus may cause various performance issues, including strange behavior on the display like flickering or lines.

4. Overheating

Another significant factor that can cause issues with your phone screen is overheating.

A. Thermal Expansion

Excessive heat can lead to thermal expansion of the components within the phone.

• Component Damage: When parts expand too much, it may harm internal connections and the performance assembly, potentially leading to horizontal lines on the screen.

B. Performance Under Stress

Running intensive applications can cause phones to overheat.

• Gaming or Video Streaming: Activities like gaming or video playback can lead to high processing demands, generating heat and, eventually, display problems.

5. Manufacturing Defects

Sometimes, the cause of horizontal lines on the screen might be inherent manufacturing defects.

A. Quality Control Issues

During production, certain phones might have quality control oversights.

• Hastily Produced Units: If a phone is produced rapidly without adequate quality checks, it may have defects that lead to display problems like horizontal lines appearing over time.

B. Components Failure

Sometimes, components used in screen assembly fail prematurely.

• Low-Quality Parts: Inexpensive or low-quality components assembled into the device may not perform well under normal operating conditions, leading to issues.

How to Fix Horizontal Lines on Phone Screen

Troubleshooting Steps

What causes horizontal lines on phone screen? If you find yourself dealing with horizontal lines on your screen, several troubleshooting steps can be undertaken before seeking professional repair.

1. Restart Your Device

• Simple Restart: Often, the simplest solution is to restart your phone. This can eliminate temporary software glitches and refresh the device’s functions.
• Performing a Soft Reset: Sometimes, carrying out a soft reset by holding down the power button can effectively clear short-term issues.

2. Check Connections

If you feel comfortable, you can open the device to check for loose cables.

• Assessing the Internal Condition: Look for any visible loose connections, especially if your phone has recently undergone repairs. Pay close attention to the connectors linked to the display.
• Ensure Connections Are Secure: If any connectors appear loose, reconnect them to ensure secure functioning.

3. Update Software

• Keeping Software Up-to-Date: Ensure your operating system and applications are updated. Sometimes, a software update can fix display issues.
• Version Compatibility Check: Check that the latest software version is compatible with all your installed applications.

4. Reset to Factory Settings

• Last Resort Option: If the problem persists, consider performing a factory reset. This will return your smartphone to its original state.
• Backing Up Data: It’s crucial to back up any important data beforehand, as a factory reset will erase everything on the device.

5. Professional Assistance

If the troubleshooting steps do not resolve the issue, consider contacting a professional technician for assistance.

• Assessing Hardware Damage: A technician can evaluate whether there’s any unseen physical damage that requires repair.
• Repair Options and Cost Assessment: If necessary, they can provide information on the cost of parts and labor for potential repairs, such as replacing the display.

Preventing Future Issues

Regular Maintenance Tips

Preventing future issues with your phone’s display is crucial. Follow these tips to ensure longevity:

1. Use a Screen Protector

• Impact Absorption: A quality screen protector can absorb impacts and prevent scratches, which may help avoid physical damage to the display.
• Ease of Replacement: Screen protectors are relatively inexpensive and easy to replace if they sustain damage.

2. Avoid Overheating

• Keeping Your Phone Cool: Be mindful of external factors that can cause your phone to overheat. Keep your device out of direct sunlight or hot environments.
• Manage Usage: Limit prolonged sessions involving high-intensity applications or settings.

3. Handle with Care

• Use a Protective Case: Always use a protective case to provide additional security against drops or impacts. Cases can reduce the chance of damage significantly.
• Be Cautious During Use: Handle your device with care, particularly in environments where it might fall. Avoid placing your phone in precarious positions where it might slip.

4. Regularly Inspect Your Device

• Check for Wear and Tear: Routinely check for signs of wear such as loose connections or cracks. Early identification of problems can prevent more significant damage.
• Know When to Seek Help: If you notice anything unusual, consult a professional before the problem worsens.

Proper Usage Habits

• Avoid Multitasking on High-Performance Apps: Try not to run excessively demanding apps simultaneously. Giving your phone breaks can help prevent overheating and maintain optimal performance.
• Check App Activity: Occasionally review the apps running in the background. Close any unnecessary applications to free up resources.
