Booting into Safe Mode may indicate if an app is causing issues. Consider a soft or factory reset for more significant problems, and gently press the screen to realign components. If unresolved, seek professional repair for diagnostics and potential screen replacement.

What Are LCD Screen Lines On Phones?

LCD lines on a phone can be frustrating and impact your device’s functionality and appearance. These lines, which can appear vertically, horizontally, or in random patterns, typically arise due to physical damage, loose connections, software issues, or hardware malfunctions. Fortunately, you can follow several troubleshooting steps to attempt a fix before seeking professional help.

8 Methods To Fix LCD Screen Lines on Phone

Lines on your phone’s LCD screen can interfere with visibility and affect the overall user experience. Fortunately, several methods exist to address this issue, from simple software updates to professional hardware repairs. Here are a few effective solutions to restore your device’s display functionality.

Method 1: Restart Your Phone

The simplest solution, which can sometimes resolve minor software glitches, is to restart your phone. Here’s how:

  • Press and hold the power button until you see options like “Restart” or “Reboot.”
  • Select “Restart” and allow your phone to power off and back on.
  • A software issue will likely cause the display problem if the lines disappear after a restart.

Method 2: Try to Cool Down Your Phone

Sometimes, the lines you notice on your phone screen might be because of the hot temperature. So, cooling down your phone might resolve the LCD screen lines issue. Take the following steps:

  • Remove the Case: Removing your phone case improves airflow and helps dissipate heat.
  • Turn Off the Phone: Powering down allows it to cool without processing tasks.
  • Find a Cool Environment: Place the phone in a cool, dry area away from direct sunlight.
  • Avoid Charging: Disconnect from the charger while cooling to prevent additional heat generation.

If the problem continues, it is with the internal screen display, which might require professional repair services.

Method 3: Check for Software Updates

Outdated software can sometimes cause display issues. If you’re using an older version of your phone’s operating system, updating it may resolve the problem.

  • Go to Settings > System > Software Update.
  • Download and install any available updates.
  • Restart your phone after updating to see if the lines disappear.
  • This step may fix the issue if it is related to a software bug or compatibility problem.

Method 4: Boot into Safe Mode

Safe Mode turns off third-party applications and can help identify if an app is causing the screen lines. Here’s how to do it:

  • Press and hold the power button.
  • When you see “Power off,” tap and hold it until “Safe mode” appears.
  • Tap “Safe mode” to restart your phone without third-party apps.
  • If the lines disappear in Safe Mode, a downloaded app may be causing the issue. 
  • To pinpoint the cause, you can uninstall recently downloaded apps.

Method 5: Try a Soft Reset or Factory Reset

Performing a soft or factory reset may help if the screen lines persist. A soft reset involves shutting down your phone and removing the battery (if possible) to clear out minor glitches. Here’s how to Soft Reset:

  • Turn off the Phone: Press and hold the power button, then select “Power Off.”
  • Remove the Battery: (If possible) Remove the battery, wait a minute, and reinsert it.
  • Turn the Phone Back On. Press the power button to restart your device.

Note: Back up your data before performing a factory reset.

Method 6: Try a Factory Reset

Sometimes, a factory reset might help. This step will remove all apps, settings, and data, restoring your phone to its original condition. Back up your data before proceeding.

  • Go to Settings > System > Reset options > Erase all data (factory reset).
  • Confirm and allow the phone to reset. 
  • Once complete, check if the lines have disappeared.

Note: This method is only recommended if all other options fail, as it erases all personal data.

Method 7: Gently Apply Pressure to the Screen

Applying slight pressure to the screen can sometimes help realign the internal components. Note that this is a temporary fix, and it’s best done carefully to avoid further damage.

  • Turn off your phone.
  • Place a soft cloth over the screen.
  • Gently press down on the area with the lines, applying even light pressure.
  • If the lines temporarily disappear, this could indicate a loose connection, requiring a professional phone screen repair service for a permanent fix.

Method 8: Contact a Professional Repair Service

If none of the previous methods work, you should consult a specialist. Professionals can get to the root of problems, look for loose connectors, and determine if a screen has to be changed or if internal repair is required. Here’s what you can expect in a screen replacement:

  • LCD Screen Replacement: Technicians will replace the  LCD screen, often including the digitizer, if connected as a single unit.
  • Cost and Duration: LCD replacements typically cost between $50 and $200, depending on the model, and the process can take 30 minutes to an hour at a repair shop like GadgetFix.
