Green Lines in iPhone Screen: What They Mean and How to Fix

Part 1. What Is the Green Line on an iPhone Screen?

A green line on the iPhone screen can also signal a temporary software glitch, not only a hardware failure. It sometimes appears after an update due to display driver errors on OLED models, forming a straight line. This line may relate to iOS bugs, corrupted settings, or battery calibration, though drops, pressure, heat, liquid, or loose screen connectors still contribute sometimes today.

Common Causes of Green Lines on iPhone Screens

To further know why one faces green lines on the iPhone, adhere to the 5 causes in detail for clarity:

• Physical Screen Damage: A hard drop, bending in a pocket, or strong press can harm the screen’s internal layers or flex cables. Hence, this damage usually breaks pixels along a vertical or horizontal line, which shows as a permanent green stripe. Even if the phone looks fine on the outside, the internal OLED or LCD layers can still fail.
• Bad or Weak Display Connector: The screen is connected to the iPhone logic board by a short cable and connector. Thus, when this connector is loose, partially damaged, or misaligned, a section of the screen might break down.
• Manufacturing Defect or OLED Panel Failure: Certain iPhones, particularly OLED models such as the iPhone X and beyond, are capable of forming a green line without any physical harm. This occurs when a row of pixels or sub-pixels within the screen is faulty or electrically defective.
• Water or Moisture Damage: Moisture or water can get inside the phone, onto the screen circuits or connectors. Not only that, corrosion or short circuiting can occur, and the result is green lines, flickers, or unusual display patterns.
• Software Issue or iOS Bug: Sometimes, a system error, corrupted files, or a bad iOS update can cause a temporary green line. Additionally, conflicts between apps, graphics rendering, or memory issues may also show a green stripe on the screen.

Part 2. 6 Fixes— How to Resolve Green Lines on iPhone Screen

To know how you can get rid of the iPhone screen green lines, try these tested and reliable 6 fixes with detailed guidelines:

Fix 1: Force Restart Your iPhone

Ideally, a force restart cannot fix a physically damaged screen, but it can help check if a green line or green tint comes from a software problem. It clears minor iOS or graphics glitches that sometimes appear after updates or crashes. Besides, it resets a frozen or unresponsive display when a normal restart fails. Above all, it does not erase any data or settings, and is guided below for all iPhone models:

• iPhone 8 and Later: Press and release the “Volume Up” button, then press and hold the “Volume Down” button. After that, hold down the “Side” button until you see the Apple logo, then release it.
• iPhone 7/7 Plus: Hold the “Side” and “Volume Down” buttons together and keep holding until you get the Apple logo screen, then let go.
• iPhone 6S, SE (1st Gen), and Earlier: Maintain pressure on the “Home” and “Top/Side” buttons at the same time. Keep holding them until you see the Apple logo, then release them.

Fix 2: Update Your iOS Version

This solution can help if the iPhone screen has green lines because of software bugs or driver issues. Updates correct any display glitches known and add screen driver, color, and graphics enhancements. Moreover, recent versions of iOS help determine whether the issue is a software or a hardware problem. The updates also enhance the overall system stability, minimize crashes, and offer security patches. The next steps show how to do:

Step 1. Go to the “General” settings and pick the “Software Update” option.

Step 2. If there is an update, press the “Update Now” button and see if the green lines disappear after installation completes.

Fix 3: Reset All iPhone Settings

If the green line on the iPhone persists, this is a software-only step that can sometimes remove the green line without deleting photos or apps. It clears corrupted system, display, and graphics settings that may cause glitches. Moreover, this method works best with other basic fixes like force restarts and iOS updates before considering more drastic solutions. So, to know how you can safely perform this action, review the given guidelines:

Step 1. In the General settings, pick the “Transfer or Reset iPhone” option and pick “Reset” on the following interface.

Step 2. After that, choose the “Reset All Settings” option on the pop-up menu and enter the device passcode. Here, choose the “Reset All Settings” option to confirm the action and resolve green lines.

It helps you know if software steps are useless when the phone is dropped, bent, or exposed to water. Furthermore, it guides the choice between trying fixes at home or visiting a repair shop.
