Another hardware defect is also the internal issues and the bad internal parts of the iPhone. When there is a loose or defective connection between two components, e.g., the screen and the motherboard, the screen may fail to work properly.

One of the most common causes of iPhone green line issues is physical damage. The green lines appear on the screen when you drop your device or hit it hard enough that internal components get damaged.
Water Damage
Your iPhone may show green lines on the screen due to water exposure. Even minor water droplets can get into some internal components and cause short circuits and similar damage. Dry out your iPhone immediately if it has been exposed to water, and seek help from a professional.
Manufacturing Defects
Sometimes, some users experience green lines on iPhones due to manufacturing defects. These production flaws could have originated from primitive methods of manufacture and become visible after extensive use. In case of a manufacturing defect, it is best to contact Apple Support for an appropriate repair or replacement.

You can use a few different techniques to fix the green line in iPhone screen. The solutions would depend on the nature of the problem, whether it is software or hardware-related. Below, we have explained such techniques that will help you fix the iPhone green line issue.
- Method 1: Check the Liquid Contact Indicator

- Method 5: Reset All Settings
- Method 6: Erase All Content and Settings

Method 1: Check the Liquid Contact Indicator
All iPhones have a built-in Liquid Contact Indicator (LCI) which is quite small yet essential in determining any water damage. In fact, this little part may even be the first answer regarding the green line issue on the screen.
To begin checking the LCI, one must remove the SIM card tray located on the right hand side panel of the phone. This may be done using a plastic or paper clip to ease the SIM tray out gently. Please note that iPhone 14 and higher models do not come with an external LCI.
After removing the SIM card tray, grab a flashlight and highlight the area. You may want to inspect if there is a small dot present inside somewhere. If the dot is white or silver, it means that water still has not compromised your device. However, if the dot is red, expect that your device may have been immersed in water for some time.
Going through the trouble of checking the LCI is worth it because it would save you from further problems. If water damage is suspected, it is imperative you let professionals handle the repair as soon as possible.
Method 2: Update Software
