Finding a black line flashing across your iPhone 11 screen when you unlock it can be both worrying and inconvenient. The issue is known as “black lines on iPhone 11 screen,” and more and more users are reporting that they notice a horizontal line briefly appearing on the screen when turning on or unlocking their phone.

In fact, Apple has acknowledged that customers may “report seeing horizontal lines flashing briefly on the screen during these actions.” For many, this immediately raises concerns about the health of the device and the potential costs associated with repairs.

In this article, we’ll explore the causes of black lines on the iPhone 11 screen and provide practical solutions to help you effectively deal with and resolve the issue, ensuring your iPhone 11 is back to peak performance.

Why does iPhone 11 Have a Black Line on the Screen?

Many people will have confidence in the quality of iPhones until they encounter black lines on the iPhone 11 screen….

Although iPhone officials have ruled out hardware defects, some users have reported hardware defects. In addition, there are more reasons why the iPhone screen goes black.

• Software failure: Bugs or problems in the iOS operating system may cause visual artifacts, such as black lines on the screen.
• Display driver problem: The display driver controls the communication between the iPhone hardware and the screen. Failure or errors in the display driver may cause black lines to appear on the screen.
• Hardware damage: Physical damage to the iPhone, such as a drop or impact, may cause the screen or its internal connectors to fail. This damage may not always be visible from the outside, but it may cause visual problems.
• Manufacturing defects: Some iPhone 11 devices may have defects inherent in the manufacturing process. These defects will appear over time, causing problems such as black lines on the screen.
• Environmental factors: Exposure to extreme temperatures or humid environments can have an adverse effect on the iPhone display. High or low temperatures and humid environments may cause abnormal screen behavior, including the appearance of black lines.

How to Fix iPhone 11 Black Line on Screen

Although the iPhone has said: “We are aware of this problem and will soon launch a software update to solve this problem”, many users’ problems have not been solved. In addition to relying on iPhone software updates, you can also take the following methods to fix it.

Way 1. Restart Your iPhone

Sometimes, a simple restart can fix the problem that causes black lines on your phone screen.

Here are the restart methods for different iPhone models:

iPhone 8 and later models (including iPhone SE 2, iPhone X, iPhone XR, iPhone XS, iPhone 11, etc.):

• Press and hold the Side button (also called the “Power button”) and the Volume Up button until the “Slide to Power Off” slider appears.

• Press and hold the Side button again until the Apple logo appears.

Way 2. Update iOS

Make sure your iPhone has the latest iOS version installed. Go to “Settings” > “General” > “Software Update” to check and install any available updates.
