🔍 Possible Causes

The green light blinking or screen flickering issue is often linked to software updates, particularly the March 2025 security patch. Users have reported that after updating, their screens began displaying green or pink lines, or experienced flickering and color distortions. Some have noted that the issue is more prominent in dark mode or when the screen is dark .

✅ Suggested Solutions

1. Clear Cache Partition
Sometimes, corrupted system cache can cause display issues. To clear the cache partition:

Turn off your device.

Press and hold the Volume Up and Power buttons simultaneously.

Once the Samsung logo appears, release both buttons to enter Recovery Mode.

Use the Volume buttons to navigate to Wipe Cache Partition and use the Power button to select it.

Confirm by selecting Yes.

After the process is complete, select Reboot System Now.



2. Disable Hardware Overlays (Developer Options)
Some users have found that disabling hardware overlays can reduce or eliminate the green line issue:

Go to Settings > About phone and tap Build number seven times to enable Developer Options.

Navigate to Settings > Developer options.

Enable Disable HW overlays.

Restart your device.


Please note that this is a temporary solution and may not work for all users .


3. Factory Reset
If the above steps don't resolve the issue, performing a factory reset may help:

Go to Settings > General Management > Reset > Factory Data Reset.

Follow the on-screen instructions to reset your device.


Note: This will erase all data on your device. Ensure you back up important information before proceeding.


4. Contact Samsung Support
If the problem persists, it's advisable to contact Samsung Support or visit an authorized service center for further assistance. Some users have reported that the only permanent solution was to replace the display .
