Why are you seeing vertical lines on iPhone screen?

Knowing why those distorting lines have appeared on your iPhone screen is the first step towards repairing it.

  • The iPhone goes through liquid damage or overheating
  • The device drops or collides against a hard surface
  • There’s a bug in the latest iOS
  • The iPhone is too old or overworked
  • Low-quality replacement screens show vertical lines quite often

9 ways to fix the vertical lines on iPhone screen

Not every problem or distortion in an iPhone calls for a repair; sometimes, you can resolve it at home with a few easy tricks. Therefore, we have listed some quick tips to reverse the vertical lines on your iPhone screen.

Here’s what you can try to overcome this problem:

Way 1: Backup your iPhone data

When the vertical lines on your iPhone screen are persistent, they might expand and impact your device’s visibility. That’s why it’s smart to backup your iPhone data right after you’re stuck with this problem to avoid further trouble.

  1. Go to your iPhone settings, and open its general menu.
  2. Tap on the “backup and restore button” and proceed to select “backup now.”

Once your iCloud backup is complete, you can try any of the below-explained methods to fix the vertical lines on your iPhone screen.

Way 2: Backup data with iTunes

If you prefer backing up device data with iTunes, open iTunes on your computer to begin it.

  1. Connect your iPhone to the computer with a USB cable and reach the iTunes menu.
  2. Select the “backup now” option from the iTunes main menu and give it a few seconds.

Once the process is complete, your important iPhone data is safe, and you can proceed with a troubleshooting method.

Way 3: Restart the iPhone

This is the first method you should try after seeing vertical lines on your iPhone. Sometimes an overworked or overheated iPhone needs a mere restart to resume its normal functioning.

  1. Open your iPhone’s settings panel or press and hold its side and volume buttons for a few seconds.
  2. You will see a sliding bar on the subsequent screen saying “slide to power off,” slide it.
  3. Once your iPhone is powered off, press and hold its side button for a few seconds – this will restart the device.

Once the iPhone is on, see if its vertical lines have disappeared. If yes, you’re good to go. But if the problem is still there, move on to trying another method.

Way 4: Hard restart the iPhone

If your iPhone’s vertical lines have expanded and restarting it didn’t work, hard restarting is the next option. Since your device’s visibility will be hindered by now, following on-screen instructions won’t be possible.

  1. If you have an iPhone 8 or later model, press and release its volume up button and do the same with the volume down button.
  2. Next, press your iPhone’s side button and hold until the Apple logo appears on it.
  3. Now your device will force shut and restart before you can resume using it.

Note: For iPhone 7 and older models, press volume up and side buttons simultaneously until the Apple logo flashes on your screen.

Way 5: Restore your iPhone with iTunes

You can also use iTunes to restore your iPhone settings and overcome the software bug disturbing its performance.

  1. Connect your iPhone to a computer with a lighting cable and open iTunes on it.
  2. On the left side of your iTunes screen, you’ll see the devices connected to the computer; click on your iPhone to launch it.
  3. Locate the “restore iPhone” button, and allow iTunes to restore your device data.

Once the restore is complete, your iPhone’s basic settings will be back to the default mode, and hopefully, the vertical lines will go away too.

Way 6: Use the DFU method with your iPhone

The device firmware update (DFU) method will erase all codes, settings, and data on your iPhone, leaving it in the default factory mode. Therefore, backup your iPhone data to iCloud, iTunes, or another device before starting the DFU fixing method.

  1. Connect your iPhone to a computer with a USB cable while ensuring it has enough power.
  2. If you have an iPhone 7 or older model, press and hold its power and volume buttons.
  3. After a few seconds, release the power button and continue holding the volume button.
  4. When the iTunes screen flashes a message saying “iTunes has detected a phone in recovery mode,” release the volume button and complete the process.

DFU for iPhone 8 and later models:

  1. Connect your iPhone to a computer and launch iTunes on it.
  2. Briefly press the volume up button and release it. Do the same with your iPhone’s volume down button.
  3. Next, press and hold your phone’s side button until its screen goes black.
  4. Press and hold the volume down button while holding the side button.
  5. Next, release the side button but keep holding the volume button for a few more seconds until iTunes detect your iPhone.

Once your iPhone enters the DFU mode, its factory mode will be restored. The DFU method is known to overcome vertical lines on iPhones because of software and logic board glitches.

Way 7: Reset the device settings

Resetting your device can be helpful if you don’t want to risk data loss or try a more advanced troubleshooting method.

  1. Go to your iPhone’s settings menu and open the general tab.
  2. Locate the “reset” button, tap it.
  3. Allow the “erase all contents and settings” toggle in the next screen.
  4. Wait for a few seconds until your device restarts.
