Causes of a Black Screen on Your S21
Before we dive into the solutions, it’s essential to understand the possible causes of a black screen on your S21. Here are some common reasons why your phone’s display might go dark:
Software Issues
- Buggy system software: A software glitch or bug can cause your phone’s screen to malfunction, resulting in a black screen.
- App conflicts: A faulty or malfunctioning app can crash your phone’s system, leading to a black screen.
- Firmware updates: Sometimes, firmware updates can cause compatibility issues, resulting in a black screen.
Hardware Issues
- Display panel damage: Physical damage to the display panel, such as cracks or scratches, can cause a black screen.
- Loose or faulty connections: Loose or faulty connections between the display panel and the phone’s motherboard can cause the screen to go black.
- Overheating: Overheating can cause the phone’s display to malfunction, resulting in a black screen.
- Battery issues: A faulty or dying battery can cause the phone to shut down unexpectedly, resulting in a black screen.
Basic Troubleshooting Steps
Before you start panicking, try these basic troubleshooting steps to see if you can resolve the issue:
Restart Your Phone
This might seem obvious, but sometimes, a simple restart can resolve the issue. Press and hold the Power button and the Volume down button simultaneously until your phone restarts. If your phone is unresponsive, try holding the Power button for at least 10 seconds to force a reboot.
Charge Your Phone
A dead battery can cause your phone to shut down, resulting in a black screen. Try charging your phone for at least 30 minutes to see if it will turn on.
Check for Physical Damage
Inspect your phone’s display panel for any signs of physical damage, such as cracks or scratches. If you find any damage, you may need to visit a repair center or contact Samsung’s customer support for assistance.
Advanced Troubleshooting Steps
If the basic troubleshooting steps don’t work, it’s time to try some more advanced methods to resolve the issue:
Boot Your Phone in Safe Mode
Boot your phone in Safe Mode to disable all third-party apps and see if the issue persists. To boot in Safe Mode, press and hold the Power button until your phone restarts. Release the Power button when the Samsung logo appears, and then immediately hold the Volume down button.
Perform a Factory Reset
If booting in Safe Mode doesn’t work, you can try performing a factory reset. This will erase all your data, so be sure to back up your phone before doing so. To perform a factory reset, go to Settings > General Management > Reset > Factory data reset.
Check for Firmware Updates
Outdated firmware can cause software issues, including a black screen. Check for firmware updates by going to Settings > Software update > Download and install.
Hardware-Related Troubleshooting Steps
If you suspect a hardware issue is causing the black screen, try these troubleshooting steps:
Check the Display Panel

Check the Connections
Check the connections between the display panel and the phone’s motherboard. Make sure they are secure and not loose.
Check the Battery
If you suspect a battery issue, try replacing the battery or visiting a repair center for assistance.

If none of the troubleshooting steps work, it’s likely that you need to visit a repair center to diagnose and fix the issue. Here are some signs that you need to visit a repair center:
- Your phone’s screen is physically damaged: If your phone’s screen is cracked or damaged, you’ll need to visit a repair center to get it replaced.

Why did my S21 screen suddenly go dark?
Your S21 screen may have suddenly gone dark due to a variety of reasons. It could be due to a software glitch, a faulty screen, or even a hardware issue. Sometimes, a simple reboot can resolve the issue, while other times, it may require more extensive troubleshooting.
In some cases, a dark screen can be caused by a faulty charging port or a damaged screen cable. If you’ve recently dropped your phone or exposed it to water, this could be the culprit. It’s essential to identify the root cause of the issue to take the appropriate steps to fix it.
Should I try to force restart my S21?
Yes, a force restart is usually the first step in troubleshooting a dark screen issue on your S21. To do this, press and hold the Volume down and Power buttons simultaneously for at least 10 seconds. This will force your phone to shut down, and it may resolve the issue if it’s a software-related problem.
If the force restart doesn’t work, you may need to try other troubleshooting steps, such as booting your phone in safe mode or performing a factory reset. However, before taking any drastic measures, it’s essential to back up your data to prevent any loss.
How do I boot my S21 in safe mode?
To boot your S21 in safe mode, press and hold the Power button until the Power menu appears. Then, long-press the Power off option until the Safe mode option appears. Tap OK to boot your phone in safe mode. In safe mode, your phone will disable all third-party apps, allowing you to diagnose whether the issue is caused by a faulty app.
If your phone boots successfully in safe mode, it’s likely that a third-party app is causing the issue. You can then uninstall recently installed apps one by one to identify the problematic app. However, if your phone still doesn’t turn on in safe mode, the issue may be more complex and require further troubleshooting.
Will a factory reset fix a dark screen issue?
A factory reset may resolve a dark screen issue on your S21 if it’s caused by a software problem. To perform a factory reset, go to Settings > General Management > Reset > Factory data reset. This will erase all your data, so make sure to back up your important files and data before proceeding.
However, if the issue is hardware-related, a factory reset won’t fix the problem. In such cases, you may need to visit a authorized Samsung service center or repair shop to diagnose and fix the issue.
Can I fix a dark screen issue without professional help?
In some cases, you can fix a dark screen issue on your S21 without professional help. If the issue is caused by a software glitch or a faulty app, you can try troubleshooting steps like restarting your phone, booting in safe mode, or performing a factory reset.
However, if the issue is hardware-related, such as a damaged screen or faulty charging port, it’s recommended to seek professional help. Attempting to fix the issue yourself can cause further damage to your phone and void your warranty.
How long will it take to repair my S21 screen?
The time it takes to repair your S21 screen depends on the severity of the issue and the repair method you choose. If you visit a authorized Samsung service center, the repair time may vary from a few hours to a few days.
In some cases, the repair may take longer if the service center needs to order replacement parts or if there’s a backlog of repairs. It’s essential to check with the service center beforehand to get an estimate of the repair time and cost.
Is it worth repairing my S21 screen?
If your S21 screen is still under warranty, it’s worth repairing it, especially if the issue is caused by a manufacturing defect. Samsung may repair or replace your phone free of charge.
However, if your warranty has expired, you’ll need to weigh the cost of repair against the cost of buying a new phone. If your phone is relatively new and the repair cost is reasonable, it may be worth fixing. But if your phone is old or the repair cost is high, it may be time to consider upgrading to a new phone.
