Why is my phone screen black? Causes and quick fixes

Reaching for your phone only to find the screen won’t light up can be frustrating, especially when you know it’s on and should be working. Luckily, the black screen of death doesn’t always mean your phone’s life is over. 

Here’s what might be going on and what you can try to bring your screen back to life.

1. Software issues

When a phone goes dark, software-related problems are a common culprit. A recent iOS or Android update, a failed jailbreak attempt, or even conflicting apps can cause your screen to go black.

How to fix it:

• If you think your phone is broken from a jailbreak gone wrong, try a factory reset.

• Otherwise, a developer update can solve many software-related issues. To see if there’s an available update for your phone: 

  • Connect your phone to a PC, iMac, or MacBook with a USB/lightning cable.

  • Search for a downloadable update from your phone’s manufacturer.

  • Follow developer instructions to install the update.

2. Issues with the LED display

If your phone works (you can hear sounds or feel vibrations), but nothing shows up on the screen, the LED display might be busted. A hard drop or impact can easily knock things out of alignment internally.

How to fix it:

• First, try a force-restart to rule out a minor glitch.

• If resetting didn’t solve the issue, contact a phone screen repair service that can diagnose and potentially repair the broken component.

3. Overheating

Smartphones have sensitive internal components, which can sustain damage from high temperatures caused by sitting in a parked car on a sunny day, for example. Overheating can ultimately damage both the phone’s hardware and software, causing your screen to go black or glitch. 

How to fix it:

• Cool off the phone by:

  • Removing from hot area

  • Powering off

  • Taking the case off

• Avoid charging the phone until it has completely cooled since charging can generate additional heat. 

• When cooled, turn it on and update any outdated software.

• Monitor your phone’s health, especially its battery life. You may need to schedule professional services or replace parts if there’s lasting damage. 

4. Malware or viruses

Malicious apps, phishing schemes, unsecured Wi-Fi networks, and many other threats can leave your phone vulnerable to malware or viruses. Malware can cause your phone to act up, including black screen issues.

How to fix it:

• If you suspect malicious software and have tried other troubleshooting methods, don't plug your phone into other devices.

• Contact a professional repair service to safely diagnose and remove anything malicious.

5. Charging or power port problems

If your phone isn’t charging properly, it might not have enough power to light up the screen, even if it seems like it’s on.

How to fix it:

• Use a flashlight to inspect the charging port. Dust, lint, or debris could be blocking the connection.

• Gently clean it with a soft brush, compressed air, or a toothpick (be extra careful not to damage the port).

• Try a different charging cable or wall adapter.

6. Jammed or stuck buttons

A stuck power or volume button can freeze your phone or cause it to shut off or stay in recovery mode, which might look like the screen just went black.

How to fix it:

• Press each button to see if one feels “off” or sticky.

• Gently clean around the buttons with a microfiber cloth and isopropyl alcohol.

• If the issue persists, a technician may need to replace or realign the buttons.

7. In need of a factory reset

If your phone screen stays black after multiple rounds of troubleshooting, it may be time for a factory reset. Doing so will restore your phone to its factory settings, erasing everything on your device, so back up your files first.

How to fix it:

• Backup your data (options vary by model):

  • iPhones: Go to Settings > iCloud > iCloud Backup.

  • Android: Go to Settings > System > Backup.

• Factory reset:

  • iPhone: Press and hold the power + volume down buttons to trigger reset options.

  • Android: Go to Settings > System > Reset options and follow the instructions. (see full Android reset guide)

  • You do not need to remove or activate a new SIM.
