If the above doesn't fix the problem, restarting your iPhone to safe mode is a good option. This method can help you determine if a third-party app is causing the white lines on your screen. Here's how:

If the white lines disappear in safe mode, it means that a third-party app on your device may be the cause of the problem. To fix this, systematically uninstall apps one by one until you find the culprit.

Fix 6: Restore iPhone in Recovery/DFU Mode

If your iPhone continues to display white lines after trying the suggested fixes, you may need to perform a "DFU (Device Firmware Update) restore". This method goes deeper than a standard reset and can fix more complex issues.

Here are the steps to restore your iPhone in DFU mode:

• Make sure you have the latest version of iTunes installed on your computer. If not, download and install it first.
• Connect your iPhone to your computer using a USB cable and launch the iTunes app.
• Perform a force restart specific to your iPhone model to enter recovery mode. (See force restart instructions provided in Fix 1.)
• Continue holding the appropriate buttons during the force restart process until your iPhone enters DFU mode. The screen should remain blank and iTunes will detect your device.
• Once iTunes recognizes your device in DFU mode, a prompt will appear. Click "Restore" and iTunes will begin restoring your iPhone. Wait for the process to complete.

Fix 7: Restore iPhone with iTunes

Restoring your iPhone using iTunes is an effective way to fix the white lines on the screen problem. But remember that restoring a backup will overwrite your current data, so make sure you save all your important files beforehand! Here is a simple guide to walk you through the process:

• Make sure you have the latest version of iTunes installed on your computer. Launch the application and connect your iPhone using a USB data cable.
• In iTunes, click on the iPhone icon located in the upper-left corner of the screen. This will open the management page for your device.
• Select "Summary" from the left sidebar. On the right, look for the "Restore Backup" option and click it to start the process.

Fix 8: Update iOS

Updating your iPhone to the latest version of iOS can help resolve issues like white lines on the screen. Running an outdated software version can cause glitches that can lead to issues like this. Before you begin, make sure you have a stable and fast internet connection.

Here's how to update your iPhone:

• Open the "Settings" app on your iPhone.
• Scroll down and tap "General".
• Select "Software Update".
• Tap "Download and Install" to start the update.

Fix 9: Repair LCD/OLED Display

If none of the above solutions fix the problem, it's possible that your screen is damaged and needs to be replaced.

If your iPhone is still under warranty, your best option is to go to an Apple Store to have the screen replaced. However, if your warranty has expired, you can purchase a genuine Apple replacement screen from a site like Amazon and then take it to a certified repair professional to install it.
