Why Is My Lock Screen Black?

If you’re wondering why your lock screen is black, here are some possible reasons:

  • Software Glitch: Sometimes, a small software bug or glitch can prevent the lock screen wallpaper or image from loading properly. This could occur randomly or after an update.
  • System Update Problems: Updates to your device’s operating system, whether it’s iOS or Android, can occasionally introduce bugs that affect the lock screen.

How to Fix Black Screen on iPhone with 4 Useful Tips

Here, we’ll cover the top 4 helpful tips to resolve the black lock screen issue on your iPhone. We’ll begin with a straightforward solution that might be all you need, and then we’ll explore more intricate fixes for deeper repair of your device.

Fix 1: Charge Your iPhone

A frequent cause of a black lock screen, especially after updating to iOS 17 on iPhone 13/14/15, is often just a drained battery. Therefore, the initial step to address a black lock screen is to charge your device. Connect your iPhone to a charger and allow it to charge for at least 15 minutes.

After your iPhone has had sufficient time to charge, restart it by pressing and holding the Power button for a few seconds until the Apple logo appears on the screen. If all goes well, your iPhone should power on as usual.

Fix 2: Force Restart iPhone

If you’re certain that your iPhone’s battery isn’t drained, a temporary glitch within the device might be the cause. These glitches are common and usually nothing to worry about. Performing a hard reset on your iPhone can often resolve such issues.

To force restart your iPhone (8 or later), follow these steps:

  1. Press and release the Volume Up button.
  2. Quickly press and release the Volume Down button.
  3. Then, press and hold the Power button until the Apple logo appears on the screen.
  4. Wait for your iPhone to restart.

Fix 3: Restore iPhone via iTunes

If your iPhone’s screen remains black even after force restarting, you can attempt to restore your iPhone using iTunes. Restoring via iTunes is a reliable method for resolving various software-related issues, including the black lock screen problem. However, it’s essential to note that this process erases all data on your iPhone. Therefore, it’s crucial to create a backup beforehand to avoid data loss.

Here’s how to restore your iPhone via iTunes:

Putting your iPhone into DFU (Device Firmware Update) mode is an advanced troubleshooting step that allows for deep-level software recovery. In DFU mode, your iPhone can be restored to its factory settings or have its firmware reinstalled, bypassing the standard boot process.

Here’s how to put your iPhone into DFU mode:

  1. Connect your iPhone to your PC or Mac using a USB cable.

  4. Release the Power button, then press and hold the Volume Down button for another 5 seconds.

It’s crucial to remember that timing is essential when entering DFU mode. If you see the Apple logo appear during the button presses, it indicates that you held a button for too long and need to start over.
