In the worst-case scenario, additional display issues like splotches, other distracting colors, and even black marks can appear, making reading the screen difficult. So, in this guide, we’ll talk about the potential reasons behind these green lines and provide step-by-step solutions to get rid of the green line and restore your phone’s display to its former glory.

What causes green lines on mobile phone screens

Green lines on your Android phone screen can appear due to many issues, ranging from hardware issues to software glitches. Here are some of the most common causes behind green lines on mobile phone screens:

1. Physical damage

This is one of the most common reasons. A drop, bump, or exposure to liquids can damage the display itself, the display connector, or the flex cable connecting the display to the motherboard. 

2. Loose display connection

Over time, vibrations or drops can loosen the connection between the display and the motherboard. This can cause flickering, distorted colors, or green lines.

3. Incompatible app

In rare cases, a buggy or incompatible app might interfere with the way your phone renders graphics, causing visual glitches like green lines.

4. Software issues

Incorrect display settings or a recent software update gone wrong can also lead to green lines.

How to fix the green line on Android phone screens

Now that you know what causes green lines on Android phone screens, here are some ways to fix the issue:

1. Restart your phone

Most of the time a simple restart can resolve temporary software glitches that might be causing the green line.

2. Boot into Safe Mode

Safe Mode disables all third-party apps, so if the line disappears in Safe Mode, a recently installed app might be the cause. Uninstall any suspicious apps to see if that fixes the problem.

3. Update your phone

Outdated software can also sometimes cause display issues. Check for and install any available system updates.

4. Remove recently installed apps

If you notice the green line appearing after installing a new app, try uninstalling it and restarting the phone.

5. Factory Reset

If the issue persists, try factory resetting the phone. This wipes your phone back to factory settings. However, make sure to back up all your data before proceeding. If the green line disappears after a factory reset, the issue was likely software related.

If none of the above steps work, you’re likely facing a hardware problem. The green line could be caused by a damaged display panel or a loose connection. In this case:

1. Contact your phone’s manufacturer to see about warranty repairs or replacement options, if your phone is under warranty.

2. If your warranty is expired or void, reach out to a professional and trusted third-party repair service technician.

By following the above steps, you can easily diagnose the cause and potentially fix the issue yourself. If the problem lies with the hardware or the display, contact the phone’s manufacturer service and get a quote. This will help you compare with other third-party repair services to see if they’re offering a competitive price.
