So, why and how to fix red vertical line on iPhone screen? In this post, we'll show you 9 practical tips to help you solve the issue effectively.

Part 1. Why is there a red line on my iPhone screen?

There are various reasons why red vertical lines may appear on an iPhone screen, including physical damage and software issues. Below will explore some of the possible causes for this issue.

Red vertical lines on iPhones can be caused by a variety of factors. Accidental damage, such as a fall, can lead to the separation of the LCD wire from the logic board, resulting in vertical lines on the screen. Excessive Electro-Static Discharge (ESD) can also cause these lines to appear, even if the connections between flex cables and the logic board are intact. Hardware issues, such as a broken display screen, can also be a culprit. Additionally, a software glitch may sometimes be responsible for the appearance of vertical lines on the iPhone screen.

Part 2. How to fix red vertical lines on iPhone screen issue?

Tip 1: Restart your iPhone

To deal with the red line on iPhone screen, the first thing you can try is a quick restart. It can help you solve some simple iOS software bug, but it isn't 100% working. It's quick and easy, just have a shot.
