A green line on your Android phone screen can be alarming. Whether it appeared suddenly or after a drop, this issue is common among users of Samsung, OnePlus, and other Android devices. If you’re searching for how to fix green line on Android phone screen, you’re in the right place.
This article covers what causes it, how to fix it yourself (if possible), and when you need professional help.
❓ What Causes the Green Line on Android Screens?
The green line is usually caused by:
- Hardware damage: from drops, screen pressure, or water exposure
- Software bugs: often after system updates
- Display connector issues: loose or faulty internal parts
- OLED burn-in or failure: especially in AMOLED screens
🛠️ How to Fix Green Line on Android Phone Screen – DIY Methods
Before heading to a repair center, try these safe troubleshooting steps:
✅ 1. Restart Your Phone
A simple restart can sometimes fix minor glitches that cause a green line to appear.
Steps:
- Hold the Power button → Tap Restart
- Wait for the phone to reboot
This works especially if the green line appeared after an app crash or glitch.
✅ 2. Boot into Safe Mode
Safe Mode helps check if a third-party app is causing display issues.
Steps:
- Hold the Power button
- Long press “Power Off” → Tap Safe Mode
- See if the green line disappears
If the line vanishes, an app may be the culprit. Uninstall recent apps and restart.
✅ 3. Update Your Software
Sometimes, green lines appear after system updates, especially beta releases. Check if a fix is available.
Steps:
- Go to Settings → System → Software Update
- Download & install any pending updates
- Restart your phone
✅ 4. Tap Around the Screen Gently
If the green line appeared after a drop or bend, the display connector may be loose.
Steps:
- Tap gently around the edges of the screen
- Apply slight pressure with your thumb
- Restart your device
This won’t fix major hardware issues but may temporarily reconnect a loose display ribbon.
✅ 5. Perform a Factory Reset (Last Resort)
If the problem is software-related and persists, reset your device—but backup everything first.
Steps:
- Settings → System → Reset → Factory Data Reset
- Confirm and wait for the phone to reset
⚠️ This erases all data.
🔧 When to Seek Professional Repair
If none of the above works, the issue is likely hardware-related, especially in these cases:
- Green line stays in Safe Mode
- Appears after physical damage or water exposure
- Screen flickers, freezes, or touch stops responding
👉 Visit an authorized service center or contact your phone’s customer support.
