Green Line On Screen In Galaxy S24: Troubleshooting Guide

The appearance of green lines on the screen of Samsung Galaxy S24 Ultra devices has been a recurring issue for many users, often indicating a hardware fault or potential software glitch. Here are several methods to troubleshoot and potentially fix this problem.

Troubleshooting and Fixing the Green Line Issue

1. Restart Your Device

Restarting your device can sometimes resolve minor software issues that might be causing the green line to appear.

• Steps:
  1. Press and hold the Power button until the power menu appears.
  2. Select "Restart" or "Power off" and then turn the device back on.
  3. Check if the green line is still present after the restart.

2. Safe Mode Boot

Booting your device in safe mode can help determine if the issue is caused by a third-party app.

• Steps:
  1. Press and hold the Power button until the power menu appears.
  2. Tap and hold the "Power off" option until the "Safe mode" option appears.
  3. Select "Safe mode" to boot your device in safe mode.
  4. Check if the green line is still visible in safe mode.

3. Diagnostic Tool

Using the built-in diagnostic tool can help identify and potentially fix stuck pixels that might be causing the green line.

• Steps:
  1. Open the phone app and dial *#0*# before hitting the call button.
  2. This will open the diagnostic mode where you can run various tests, including a display test.
  3. Run the display test to see if it can fix any stuck pixels.

4. Master Reset

Performing a master reset can sometimes resolve software-related issues, but it will erase all data on your device.

• Steps:
  1. Go to Settings > General Management > Reset.
  2. Select "Factory data reset" and follow the prompts to complete the reset.
  3. After the reset, check if the green line is still present.

5. Contact Samsung Support

If the issue persists, it may be a hardware fault that requires professional attention.

• Steps:
  1. Contact Samsung support via their website, phone, or visit a Samsung service center.
  2. Explain the issue and provide any necessary details or proof of purchase.
  3. Follow their instructions for repair or replacement, which may include a free screen replacement in some regions.

6. Check for Physical Damage

Green lines can also appear due to physical damage such as dropping the phone or bending the screen excessively.

• Steps:
  1. Inspect your device for any signs of physical damage.
  2. If you find any damage, contact Samsung support to see if it is covered under warranty or if you need to pay for repairs.

7. Avoid Overheating

Overheating can sometimes cause display issues, including green lines.

• Steps:
  1. Avoid using your device in extremely hot environments.
  2. Close resource-intensive apps and background processes to reduce heat generation.
  3. Use a cooling pad or case if necessary to keep your device cool.

8. Software Update Check

Ensure your device is running the latest software, as updates may include fixes for display issues.

• Steps:
  1. Go to Settings > Software update > Download and install.
  2. Follow the prompts to update your device to the latest software version.
  3. Check if the green line issue is resolved after the update.

By following these steps, you may be able to troubleshoot and fix the green line issue on your Samsung Galaxy S24 Ultra. If none of these methods work, it is likely a hardware fault that requires professional repair or replacement.
