Are you frustrated with a green line appearing on your Android phone screen? Don’t worry, we’ve got you covered!

In this tutorial, we will guide you through the steps to fix this issue. So, let’s dive in and get your phone screen back to normal!

1. Restart Your Phone

If you notice a green line on your phone screen, the first thing you should try is restarting your device. This simple step can often resolve minor software glitches that may be causing the issue.

2. Update Your Android Software

If restarting doesn’t work, it’s time to check for any pending software updates for your Android device.

Manufacturers regularly release updates to fix bugs and improve performance. To update your software:

  • Step 1: Go to the “Settings” app on your phone.
  • Step 2: Scroll down and tap on “System” or “About Phone. “
  • Step 3: Look for “System Updates” or a similar option.
  • Step 4: If an update is available, download and install it.

3. Check for App Updates

Sometimes, an outdated app can cause display issues on your Android phone.

To check for app updates:

  • Step 1: Open the Google Play Store.
  • Step 2: Tap on the three horizontal lines at the top-left corner of the screen.
  • Step 3: Select “My apps & games. “
  • Step 4: If any updates are available, tap the “Update” button next to the app.

4. Clear Cache and Data of Problematic Apps

If the green line appears specifically when using certain apps, clearing their cache and data can help resolve the issue.

Here’s how:

  • Step 1: Go to “Settings” on your Android device.
  • Step 2: Tap on “Apps & notifications” or a similar option.
  • Step 3: Locate the problematic app and select it.
  • Step 4: Tap on “Storage & cache. “
  • Step 5: Finally, tap on “Clear cache” and “Clear storage. “

5. Perform a Factory Reset

If none of the above solutions work, you may need to perform a factory reset as a last resort. However, please note that this will erase all data on your phone, so make sure to back up your important files beforehand. To perform a factory reset:

  • Note: The steps may vary slightly depending on your device model and Android version.
  • Step 1: Open the “Settings” app.
  • Step 2: Scroll down and tap on “System” or “General management.

  • Step 3: Select “Reset” or “Reset options. “
  • Step 4: Choose “Factory data reset” or “Erase all data. “
  • Step 5: Follow the on-screen instructions to complete the process.


In most cases, the green line on your Android phone screen can be fixed by following the steps mentioned above. Remember to start with the simpler solutions like restarting your device and checking for software updates.

If the issue persists, try clearing cache and data of problematic apps before resorting to a factory reset. Hopefully, your phone screen will be back to normal after trying these troubleshooting methods!
