What Is The Green Line Problem On The Phone Screen, And How Can It Be Resolved?
AMOLED screens have become the standard for both flagship and mid-range smartphones, offering deep blacks and energy efficiency. However, the “green line” issue has been reported recently, particularly on phones with AMOLED displays. This article explores what causes the green line issue on Android phones and how to resolve it.
What is the green line issue on phones?
A green line that cuts through the display has been a common complaint among smartphone users. This narrow strip extends from the top to the bottom of the screen. While the phone functions normally, the green line is an obvious and irritating flaw.
Many users report that the green line appears without any drop or water damage. Some believe the issue arises after a software update.
Various smartphone manufacturers, including Samsung, OnePlus, OPPO, realme, vivo, iQOO, Xiaomi, Motorola, Nothing, HUAWEI, and even Apple, have experienced this issue. This suggests that it may be more of a hardware defect than a software one. The problem occurs across all price ranges, from mid-range to high-end flagship models.
The common factor in these reports is the AMOLED display. The issue mostly affects phones that are one to two years old and, unfortunately, out of warranty. While one green line is most common, additional lines or pink or white discoloration may also appear, worsening the problem.
The green line may occasionally flicker and appear briefly, but in most cases, it is persistent and visible on the home screen, lock screen, and Always-On display.
Why Does a Smartphone Screen Have a Green Line?
A green line can appear for several reasons. If accompanied by other colors, the screen might be shattered, especially if there is visible glass damage. A single, thin green line can be caused by:
- Loose display connection
- Damaged display connection
- Water or fall damage
- Defective application
- Incorrect configuration
How to fix the green line issue on your phone screen
Unfortunately, the only permanent solution to the green line problem is display replacement. However, you can try these steps first:
- Restart your phone: Turn it off completely, then turn it on again. If the green line was caused by a temporary software glitch, this might fix it.
- Restart in Safe Mode: If the green line doesn’t appear in Safe Mode, it could be a software issue, possibly caused by an app or setting.
- Delete recently installed apps: If an incompatible or malfunctioning app is the culprit, deleting it might solve the problem.
- Update your phone: Check for any available operating system updates, which might resolve the issue.
- Factory reset your phone: As a last resort, try a factory reset. This will erase everything on your phone and reinstall Android. If the green line persists, it’s likely a hardware failure.
Note: Try the non-destructive tips above first. If you opt for a factory reset, back up your data to avoid losing important files.
