When you tried to unlock your iPhone today, were you seeing a green line on your iPhone, or perhaps multiple green lines? We're assuming you tried restarting your iPhone, thinking it's due to a software issue, and that it should help fix it.

Green Line on the iPhone Screen: Possible Reasons

Firstly, the green line on iPhones is most noticeable on models with OLED displays, compared to iPhones with LCD screens. The iPhone uses a diamond sub-pixel pattern for its OLED screen. If something goes wrong, the display of your iPhone shows a straight green line on one or multiple sides of the display.

And we're sure you're confused as to why there are strange green lines suddenly on your iPhone and what could've gone wrong. Here are some of the reasons that damaged your iPhone's display, creating strange green lines on your iPhone:

  • The iPhone's connection to the LCD from the digitizer was not installed properly when it was manufactured.
  • It can be due to liquid damage.
  • The display of your iPhone suffered a great impact, such as falling from a large height or sleeping on it for many hours.
  • A component inside could have been short-circuited.

Now that we know a few possible reasons that are the culprit behind the green line on your iPhone let's look at a few solutions that should stop this from growing further, at least temporarily.

How to Fix the Green Line on the iPhone Screen

Here are some solid solutions that are guaranteed to help you remove the green line from your iPhone's screen.

1. Force Restart your iPhone

There's a huge difference between restarting your iPhone and force restarting it. In the latter, you kill the power off of your iPhone. You force it to shut down rather than systematically following the procedure and turning it down and turning it back on.

When you perform a force restart, your iPhone immediately shuts down, and any problems that would have occurred due to short-circuiting or wetness wouldn't grow serious because the power is cut off.

Here's how to force-restart your iPhone:

Step 1. Press and release the volume-up button.

Step 2. Immediately press and release the volume down button.

Step 3. Now, press and hold the power button, and keep holding it until your iPhone powers off and shows a black screen.

Now you can choose to power it back on immediately by pressing and holding the power button, or you can choose to keep it off for a few days and then power it back on.

You should keep it off for a few days if you think water could have seeped into your iPhone when you took it with you for a swim or recently put it under the water to take pictures.

2. Check your iPhone for water damage

Checking if your iPhone's screen is showing green lines because of water damage is technically easy and simple. Here's what you need to do:

Step 1. Take out your SIM ejector tool and eject the SIM card tray.

Step 2. Check if there are any droplets of water on the SIM card tray, or touch the SIM card tray to see if it's moist or wet.

If you don't find any traces of water by ejecting and examining the SIM card tray, check if the LCI is white or red.

Apple built a water damage detector inside your iPhone to determine if water damage was the reason for the green line issue or for any other water-related issues, even short-circuiting.

The LCI, which is short for "liquid contact indicators," is a water damage detector that turns red when water gets into your iPhone.

Here's how to check if the LCI is white or red:

  • After you've removed the SIM card tray, use a torchlight to see if the LCI is red or white inside the iPhone.
  • If it is white, the issue is not because of water damage.
  • If the LCI is red, the issue could be because of water damage.

Turn off your iPhone for a few days and keep it in a cool, dry place.

3. Reset iPhone Settings

Resetting iPhone settings has been shown to temporarily resolve the issue for some users. Here's how to reset iPhone settings:

Step 1. Open "Settings."


Step 2. Tap on "General," and then select "Transfer or Reset iPhone."

Step 3. Tap on "Reset" and select "Reset All Settings."

Step 4. Enter your iPhone's passcode if prompted.

Now restart your iPhone and check if the green lines on your iPhone are minimized.

4. Run your iPhone in Recovery Mode

Run your iPhone in recovery mode if resetting the settings didn't help either. Here's how to do that:

Step 1. Plug your iPhone into your computer.

Step 2. If you're on Windows, launch iTunes, and if you're on a Mac, launch Finder.

Step 3. Now press the volume up button and then immediately press the volume down button.

Step 4. Press and hold the power button.

Step 5. On your iTunes or Finder window, select "Check for Update."
