Causes of Black Line on iPhone 11 Screen

There are several reasons why your iPhone 11 may display a black line:

  1. Software Glitches: Occasionally, a minor software bug can cause display issues like black lines.
  2. Physical Damage: Dropping your phone or exposing it to impact can damage the screen or internal components, leading to black lines.
  3. LCD Cable Disconnection: The most common cause is the disconnection of the LCD cable from the logic board, which can happen due to physical shocks or manufacturing defects​​.
  4. Liquid Damage: Exposure to water or other liquids can also lead to screen issues, including black lines.
  5. Broken LCD: This is the most common cause of this and would mean you’d have to replace the LCD.

Troubleshooting Steps

Restart Your iPhone

A simple restart can sometimes resolve minor software glitches that might be causing the black line:

  1. For iPhone 8 or Older: Press and hold the power button until the “slide to power off” option appears. Swipe the icon to turn off your phone, wait a few seconds, then press and hold the power button until the Apple logo appears.
  2. For iPhone X or Newer: Press and hold either volume button and the side button until the “slide to power off” option appears. Swipe to turn off your phone, then press and hold the side button until the Apple logo appears​​.

Hard Reset

If the black line is severely obstructing your view, a hard reset may be necessary:

  • iPhone 6s and Earlier: Simultaneously press and hold the Home button and the power button until the Apple logo appears.
  • iPhone 7 and 7 Plus: Press and hold the volume down button and the power button simultaneously until the Apple logo appears.
  • iPhone 8 and Newer: Quickly press and release the volume up button, then the volume down button, then press and hold the side button until the Apple logo appears​​.

Backup Your iPhone

If the issue persists, back up your iPhone immediately. This ensures that your data is safe in case the problem is indicative of serious hardware damage. Use iTunes or iCloud for backup. For iTunes, connect your phone to a computer with a Lightning cable. For iCloud, ensure you have sufficient storage space​​.

DFU Mode Restore

The Device Firmware Update (DFU) restore is a more comprehensive solution. It completely erases and reloads your iPhone’s code, restoring it to factory defaults. Ensure you back up your iPhone before proceeding with a DFU restore​​.

LCD Screen Replacement

If the software / troubleshooting methods above don’t work, you likely have a broken LCD screen. You should check with Apple first to see if there’s anything they can do about it (especially if you still have an active AppleCare+ plan or are still in warranty. They won’t likely do anything for you, however, as the iPhone 11 is largely out of phase at this time.

So your best bet is to take your iPhone 11 into a 3rd party repair shop to have the screen replaced.

Professional Repair Options

If the above steps do not resolve the issue, it is likely a hardware problem. Consider the following:

  • Apple Store Appointment: Schedule a visit to your local Apple Store, especially if you have AppleCare+. Apple technicians can diagnose and repair your device.
  • On-Demand Repair Services: Companies like Puls offer on-demand repair services. They can send a certified technician to your location to fix the issue, often within an hour​​.

Preventive Measures

To prevent such issues in the future, consider the following:

  1. Use Protective Cases: A robust case can mitigate the impact of falls and reduce the chances of internal damage.
  2. Avoid Exposure to Liquids: Keep your iPhone away from water and other liquids to prevent liquid damage.
  3. Regular Software Updates: Keep your iOS updated to avoid software-related screen issues.
