Fix White Lines On The iPhone Screen

We understand how upsetting it is to spend hundreds of dollars on a new iPhone to have it develop the dreaded “white line on iPhone screen” problem after only a few months of use. If this is the case, you do not need to be concerned or spend sleepless nights, and you should take heart from the knowledge that millions of iPhone users are experiencing the same issue.

While we’re at it, if you’ve been looking for a solution to remedy the white lines on your iPhone screen, this article will equip you with thorough methods on how to fix the white lines on the iPhone screen problem, as well as some underlying causes of the problem.

What is the Source of White Lines on the iPhone Screen?

White lines on your iPhone screen might occur for various reasons, and some are relatively easy to spot, while others are more challenging.

Below are some of the causes of the white lines on your screen:

Flex Cable Problem: White lines appear on your screen when your iPhone’s flex cables are not correctly connected. In other words, the problem is caused by a faulty connection.

Electro Static Discharge: Electro-static discharge can also cause white lines on your iPhone screen since it damages the phone’s internal functioning.

Broken Screen: A broken screen is a common cause of white lines on your iPhone’s screen. The screen can be broken if it falls on the ground or any other hard surface, causing damage to the screen and the appearance of a white line.

Dropped iPhone in Water: The white lines on the iPhone screen can also be created by dropping your phone in water. Without a doubt, the water destroys the phone’s internal functioning, particularly its screen, which is one of the iPhone’s most sensitive elements.

Loose LCD Cable Connection: When the LCD cable connection on your iPhone is loose, you may observe white lines on the screen. The reason for this is that you may have replaced the front of your iPhone, but with a screen that does not have the Apple cushion attached. As a result, the cable connection is no longer the same as before.
