Your iPhone, like any other electronic device, helps you perform many everyday tasks on a daily basis. However, it will also deteriorate over time and become faulty, most frequently affecting either the battery or the screen of the phone. 

One of the most common issues we face is when you’re seeing lines on your iPhone’s screen and you wondered why it happened. The lines could be any color such as white, black, or green. It could also occur on half of your screen or maybe the whole screen infected by these lines.

This issue usually occurs when the iPhone’s LCD cable gets disconnected from the logic board due to dropping the phone or gets water damaged and results in a software problem. We are going to explain why there are lines on your iPhone screen and tell you how to fix the issue.

Do a hard reset on your iPhone

To rule out software issues, all you have to do is hard reset your iPhone. Hard resetting your iPhone will let all of the programs shut down normally, which could fix the issue that causes lines to appear on your iPhone’s screen.

Follow these steps to hard reset your iPhone if you own an iPhone 8 model onwards:

  1. Press volume up and immediately press volume down
  2. Immediately press and hold the power button
  3. Keep pressing and then release the power button until the white Apple logo appears on screen
Follow these steps if you own an iPhone 7 and iPhone 7 Plus:
  1. Press and hold the volume down button and the power button
  2. Keep holding and then release all the buttons until the white Apple logo appears on screen
Follow these steps if you own an iPhone 6s and older model:
  1. Press and hold the home button and the power button
  2. Keep holding and then release all the buttons until the white Apple logo appears on screen

Backup Your iPhone

This may not be a step to fix the lines on your iPhone screen, but it may help you later. Do a backup on your iPhone immediately if you still see a line even after a hard reset. This is to store all your data just in case the issue gets bigger or have the phone memory wiped completely if you are performing the DFU mode.

There are 2 ways to backup your iPhone, first is the iTunes backup, you’ll need a computer and a cable to  connect your iPhone. Second, you can backup on iCloud, if you have enough storage on iCloud to do so.

How to do an iTunes backup:

1. Connect your iPhone to your computer

And that’s how you do a backup on your iPhone. If you want to backup on iCloud but don’t have enough storage, you can expand it with subscribing iCloud+ starting from S$1.28 for 50GB. 

Enter DFU Mode 

DFU (Device Firmware Update) is when your computer erases and reloads every bit of code that controls the software and hardware on your iPhone. All the data on your iPhone will be lost and there is the potential for something to go wrong if you decide to follow this step, therefore backup your iPhone before you go into DFU Mode. You can watch how to perform a DFU mode or you can follow these steps instead. 

How To Put An iPhone 7 Or Older In DFU Mode:

  1. Plug your iPhone into your computer and open iTunes if you have a Mac running macOS Mojave 10.14 or a PC. Open Finder if you have a Mac running macOS Catalina 10.15 or newer. It doesn’t matter if your iPhone is on or off.
  2. Press and hold the Sleep / Wake Button and Home Button (iPhone 6s and below) or the volume down button (iPhone 7) together for 8 seconds.
  3. After 8 seconds, release the Sleep / Wake Button but continue to hold the Home Button (iPhone 6s and below) or the volume down button (iPhone 7) until your iPhone appears in iTunes or Finder.
  4. Let go of the Home Button or volume down button. Your iPhone’s display will be completely black if you’ve successfully entered DFU mode. If it’s not, try again from the beginning.
  5. Restore your iPhone using iTunes or Finder.
How To Put An iPhone 8 Or Newer In DFU Mode:
  1. Quickly press and release the volume up button, then quickly press and release the volume down button, and then press and hold the side button until the screen goes black.
  2. As soon as the screen turns black, press and hold the volume down button while continuing to hold the side button.
  3. After 5 seconds, release the side button while continuing to hold the volume down button until your iPhone shows up in iTunes or Finder.
  4. As soon as it appears in iTunes or Finder, release the volume button. Ta-da! Your iPhone is in DFU mode.

Note: If the Apple logo is appearing on the screen, that means you have held down the volume down button for too long. Start the process over from the beginning and try again.

This DFU mode functions to rule out all possible software issues, and if after this process the lines still appear on the screen, then the problem may be caused by a hardware issue and you would then need an iPhone screen replacement.
