Your iPhone 12 may have advanced features, but it’s not immune to randomly getting stuck on a black screen.

When this happens, your instincts tell you to aggressively tap on your display. And now you’re here because that didn’t work.

We got you. In this article, we’re going to show you multiple ways to restore your iPhone 12 to normal functionality.

From simple one-minute fixes to a complete data wipe, we’re going to guide you throughout the entire process.

Let’s start repairing!

Why Is My iPhone 12 Screen Black?

A black screen can be caused by multiple underlying issues. Your software may have been corrupted, or an update was improperly installed.

It’s also possible that your iPhone 12 sustained damage from being dropped or other hard impact, disconnecting a wire or two. Even worse, liquid may have gone inside your iPhone.

1. Back Up Your iPhone

Before committing to do any of the following procedures, a good measure is to back up your iPhone 12.

In doing so, you can restore your data should you proceed with a solution that involves wiping out your iPhone. There are multiple ways to backup your device and all of them use Apple’s own programs.

You can directly back up your iPhone 12 to iCloud from the phone itself but since you can’t toggle your display due to the black screen issue, connect to a PC or Mac and follow the steps below.

Using iTunes to back up your iPhone 12:

  1. Connect your iPhone to a Windows PC or a Mac running macOS 10.14 and older.
  2. Launch iTunes and click the iPhone icon on the upper-left corner of the window.
  3. Then, make sure to select the circle next to This Computer.
  4. Lastly, click the Back Up Now button.

Using Finder to back up your iPhone 12:

  1. Connect your iPhone to a Mac that’s running macOS 10.15 or newer.
  2. On your Mac, open the Finder app.
  3. On the left-hand panel, select your iPhone 12 found under Locations.
  4. Then, select Back up all of the data on your iPhone to this Mac.
  5. Lastly, click the Back Up Now button.

This entire process can take up to several minutes depending on the speed of your iPhone 12 and computer.

2. Force Restart Your iPhone 12

One solution you can perform on your iPhone 12 is a force restart. As the name implies, it forces your device to shut down and then turn on again.

This can hopefully resolve any small firmware or software issues your iPhone 12 may be experiencing.

Performing a force restart is not too complicated and can be done in a minute or two. A forced restart will disconnect the electricity flowing from your battery to your phone, forcing it to shutdown and restart.

The restarting process isn’t any different from the normal restart, so we only recommend doing this for situations where you can’t interact with your screen.

Here’s how to do so:

  1. Quickly press then release the volume up button on your iPhone 12.
  2. Do the same for the volume down button.
  3. Then, press and hold the power button for 10 seconds.
  4. When it boots up, wait for the Apple logo to appear. Once it does, release the power button.
  5. Wait until your device finishes booting up.

If a firmware or software issue is causing the black screen, then this should fix your problem. If you fail to properly execute the button sequence, you simply need to restart the process and do it all over again.

3. Charge Your Device and then Do a Force Restart

Did your iPhone 12 not respond even after performing the correct button sequence of doing a Force Restart? This may be caused by an empty battery.

With your phone display being all black, it’s impossible to know if your phone doesn’t have any juice left.

Either way, it’s a good measure to charge your iPhone 12 for at least 10 minutes before performing a force restart. Once you have, you can then perform a force restart using the same button sequence mentioned earlier.

Whether the charging sign shows up or not, leave your iPhone connected to the outlet anyway. Once you’ve charged your device and performed a force restart, the black screen should now go away. If this didn’t resolve the issue, then head to the next solution.

4. Try TinyFix to Repair iPhone 12 System Issue

A recovery program tool you can use to easily resolve any system issue is TinyFix. You can use this to fix all sorts of problems with your smartphone, including the black screen issue you’ve encountered without data loss.

Fortunately, TinyFix works for all iOS devices, including the iPhone 12. To use this tool, you’ll simply need to connect your iPhone to a computer and open TinyFix from there.

Using TinyFix on your iPhone 12:

  1. Download TinyFix, install and launch TinyFix once the download is finished.
  2. Then, connect your iPhone 12 to your computer.
  3. Once your iPhone has been detected, select iOS System Repair and then Standard Repair Mode. If it cannot be detected, make sure to follow the steps on getting your phone to Recovery Mode on the TinyFix program.
  4. Select Download to download a clean version of your iPhone’s firmware.
  5. Once the download is complete, select Fix Now.
  6. Wait until your iPhone reboots.

Standard Repair Mode

If your firmware is corrupted, then you’ll need to replace it with a working version. Once you do so, any corrupted code messing with your device should get wiped out along with the old firmware you’re replacing. With TinyFix, doing this firmware fix should not delete your local data.

5. Put Your iPhone in DFU Mode

A Device Firmware Update is the most thorough solution you can do to your iPhone 12. Consider Updating or Restoring your phone in Recovery Mode first before doing this.

You should only use the DFU method if you have a hard time entering Recovery Mode the normal way.

Note that the button sequence to enter DFU Mode is more complicated than a force restart, and you may have to perform this multiple times if you fail to do it correctly.

Also, it is highly recommended that you back up your iPhone 12 as this will completely wipe out all of your device’s data.

Performing a DFU on your iPhone 12:

  1. Connect your iPhone to a PC or a Mac that has either iTunes or Finder.
  2. Press then quickly release the volume up button.
  3. Next, immediately do the same for the volume down button.
  4. Once you’ve let go of the volume down button, hold down the side button for a few seconds.
  5. Now, press and hold the volume down button while still holding down the side button.
  6. After 5 seconds, release the side button only.
  7. Once iTunes or Finder detects your iPhone, let go of the volume down button.
  8. On either of the apps, select Restore.
  9. Make sure to keep your iPhone plugged in until the process finishes.

This should fix whatever software issue the device is experiencing. Your iPhone 12 will now seem brand new as all of its software has been reset and you’ll need to set up your device again.

If the black screen is still there, then the problem may have been caused by a hardware issue.

6. iPhone 12 Hardware Repair

If none of the methods above fixed your iPhone 12, then a hardware issue may have caused the black screen. You can visit Apple’s website to find professional support for your issue.
