A green line can sometimes be caused by physical damage to the device such as a cracked screen or a damaged display component.

Testing in Safe Mode is a valuable diagnostic step that can help identify the root cause of the green line problem on your Samsung device and guide you towards an appropriate solution.

5. Update Software

Software Update

Software updates often includes bug fixes, performance improvements, and display enhancements that can address issues affecting the display, including the green line problem. By ensuring that your Samsung device is running the latest software version, you can potentially resolve any software-related glitches or compatibility issues that may be causing the green line.

Updating the software is a simple yet powerful solution that may eliminate the green line and restore a normal display on your Samsung device.

6. Reset App Preferences

App preferences are the default settings and permissions for individual apps on your device. Resetting them can help resolve any misconfigurations or conflicts that may be causing the green line.

This step is often effective in addressing various display issues, including the green line problem, and can help restore the optimal functionality of your Samsung device’s display. Reset app preferences in Settings.

7. Wipe Cache Partition

Over time, temporary system files can accumulate and cause conflicts that affect the display, including the appearance of a green line.

Wiping the cache partition is a straightforward process that can be performed from the device’s recovery mode and may help eliminate the green line and restore a normal display on your Samsung device.

8. Factory Reset as Last Resort

Factory reset restores device to its original or factory settings, effectively wiping all data and settings. While this step should only be considered as a last resort due to its drastic nature, it can be effective in resolving persistent issues, including the green line problem.

However, it’s crucial to note that a factory reset should be approached with caution as it deletes and erases all personal data. Before proceeding with a factory reset, ensure that you have backed up all important data and have exhausted all other potential solutions.

9. Get Professional Repair

A green line can sometimes indicate a hardware issue that requires expert attention. Professional technicians have the knowledge and tools to diagnose and repair hardware problems accurately.

By opting for professional repair, you can ensure that your Samsung device receives the necessary expertise and care to address the green line issue effectively.
