Experiencing a black screen on your Samsung S21 can be a frustrating dilemma. This issue can arise at unexpected moments, leaving you unable to access important information or use your phone altogether. Fortunately, there are several methods to troubleshoot and potentially resolve the problem. In this article, we will delve into a variety of techniques that can help you restore functionality to your device.
Understanding the Black Screen Issue
When faced with a black screen on your Samsung S21, it’s essential to identify whether the device is truly off or if software/hardware issues are at play. There are a few key scenarios that could lead to a black screen on your phone:
Common Causes of Black Screen
- Software Glitches: Occasionally, software bugs can cause your device to freeze or fail to respond, resulting in a black screen.
- Battery Issues: A drained or faulty battery can also lead to a situation where the screen remains black.
- Physical Damage: Any form of physical damage, including water damage, can compromise the screen’s functionality.
- External Factors: Sometimes, improperly connected accessories or apps running in the background can interfere with your device.
Understanding the potential causes can help you implement the right solution for your problem.
Initial Steps to Troubleshoot
Before diving into intricate troubleshooting methods, it’s wise to start with basic checks that might resolve the black screen issue:
Force Restart Your Device
A force restart can often resolve minor glitches that may be causing the black screen. Here’s how to do it on your Samsung S21:
- Press and hold the Volume Down button and the Power button simultaneously.
- Continue holding the buttons until you see the Samsung logo, which may take about 10 to 15 seconds.
- Release the buttons, and your phone should restart.
This method is simple but can be effective in fixing temporary software issues.
Check for Battery Status
A low or expired battery can also lead to a black screen. Connect your phone to a charger and wait for a few minutes. If the battery was drained, you might see the charging icon on-screen. If there is no response after being connected to a charger, consider testing with another charger or cable to rule out any issues with your charging accessories.
Advanced Troubleshooting Techniques
If the initial steps did not yield results, you may need to explore more advanced troubleshooting techniques to fix the black screen issue with your Samsung S21.
Booting into Safe Mode
Booting your device into Safe Mode can help determine if a third-party app is causing the black screen. When in Safe Mode, only pre-installed apps will run, allowing you to diagnose the issue.
How to Enter Safe Mode
- Press and hold the Power button until the Power Off icon appears.
- Tap and hold the Power Off icon until you see the Safe Mode prompt.
- Tap Safe Mode to confirm.
Your phone will reboot in Safe Mode. If the screen works properly, it is likely that a third-party app is the culprit. To resolve this, you can uninstall recently downloaded apps one by one until you identify which one is causing the issue.
Clearing Cache Partition
Sometimes, a corrupted cache can lead to performance issues, including a black screen. Cleansing the cache partition can refresh your device without deleting any personal data.
Steps to Clear Cache Partition
- Turn off your Samsung S21.
- Press and hold the Volume Up and Power buttons simultaneously until the Android logo appears.
- Navigate to the Wipe Cache Partition using the volume buttons and confirm with the Power button.
- Select Yes to clear the cache.
After this process completes, select Reboot system now to restart your device. This could potentially clear issues associated with the cache and restore functionality.
Hardware Troubleshooting
If the software fixes have not resolved the issue, you may be dealing with a hardware problem. Below are the hardware checks you should consider.
Inspect for Physical Damage
Check your device for any visible signs of damage, including cracks on the screen or signs of water damage. If physical damage is evident, it might be necessary to consult a repair professional or visit a Samsung service center.
Replace the Screen or Battery
In some cases, a faulty screen or battery may be the cause of the black screen. If you are familiar with smartphone repairs, you might consider replacing these components yourself. However, it’s highly recommended to seek professional help if you are unsure.
When to Seek Professional Help
If all else fails, it might be time to consider seeking professional assistance. Samsung-certified technicians have the experience and tools necessary to diagnose and fix hardware issues effectively.
Contact Samsung Customer Support
If your device is under warranty or if you have Samsung Care, contacting Samsung Customer Support can be a viable option. They can guide you through troubleshooting steps or arrange for repairs if necessary.

What causes the black screen issue on the Samsung S21?
The black screen issue on the Samsung S21 can stem from various factors, including hardware malfunctions, software glitches, or battery issues. A common cause is a drained battery or a faulty charger, which prevents the device from turning on properly. Additionally, critical software updates or installation errors can lead to a malfunction, rendering the screen unresponsive.
Sometimes, physical impacts like drops or exposure to water can also damage the internal hardware, leading to the black screen problem. It’s vital to rule out these issues before delving into software-related fixes or seeking professional assistance.
How do I perform a soft reset on my Samsung S21?
A soft reset is a simple method that can resolve many minor issues, including the black screen. To perform a soft reset on your Samsung S21, press and hold the Volume Down and Power buttons simultaneously for about 10 to 15 seconds. You should see the Samsung logo appear, indicating that the device is rebooting.
This process does not erase any data on your device, making it a safe first step to try. After the reset is complete, check if the screen turns on and functions properly. If the issue persists, further troubleshooting may be necessary.
What is Safe Mode, and how do I activate it?
Safe Mode is a diagnostic setting on your Samsung S21 that allows you to run the device without any third-party apps. This can help determine if the black screen issue is being caused by an incompatible app or a software conflict. Activating Safe Mode is straightforward; simply press and hold the Power button until the Power off menu appears, then press and hold the “Power off” option until you see “Reboot to Safe Mode.” Tap “Safe Mode” to confirm.
Once in Safe Mode, check if your screen is functional. If it works properly, this indicates that a third-party app may be causing the problem. You can then exit Safe Mode and proceed to uninstall recently installed or suspicious applications to resolve the issue.
How can I check if my battery is the issue?
If you suspect that the battery is causing the black screen issue, there are a few steps you can take to investigate. Start by connecting your Samsung S21 to a charger and wait for a few minutes to see if it responds. Look for the charging icon or any signs of life on the screen. If there’s nothing but a black screen, it might indicate a dead or malfunctioning battery.
You can also try different chargers and cables to rule out issues with the charging accessories. If the device still won’t turn on, it may be best to contact a professional technician for a battery check or replacement, as handling batteries can be delicate and requires proper tools and expertise.
What should I do if the screen remains black after a software update?
If the screen remains black following a software update, it’s possible that the update did not install correctly. In this case, a soft reset or force restart might help to resolve the issue. To do this, press and hold the Volume Down and Power buttons for about 10 to 15 seconds until the Samsung logo appears. This can help refresh the system and restore functionality.
If a reset doesn’t work, you may need to consider entering recovery mode. This allows you to wipe the cache partition or perform a factory reset if necessary. Remember that a factory reset will erase all data on your device, so it’s recommended to have a backup if you choose this option.
What steps should I take if my Samsung S21 is still under warranty?
If your Samsung S21 is still under warranty, the best course of action is to contact Samsung’s customer support or visit an authorized service center. They can assess the device for any hardware or software issues that may be causing the black screen problem. Since it is under warranty, repairs or replacements may be covered at no cost, depending on the terms of the warranty.
Always ensure you have your purchase receipt and any relevant documentation ready when contacting customer support. This will help expedite the process and determine your eligibility for warranty service. Avoid attempting any repairs yourself, as this may void the warranty.
Can a factory reset help fix the black screen issue?
A factory reset can be a solution for fixing a black screen issue if other troubleshooting methods fail. This process will erase all data, settings, and apps on your Samsung S21, effectively restoring it to its original factory state. Before performing a factory reset, it’s crucial to back up your data if possible, as this process will lead to permanent data loss.
To perform a factory reset, you can access the recovery mode by turning off the device, then pressing and holding the Volume Up and Power buttons simultaneously until you see the Android recovery screen. From there, navigate to the “Wipe data/factory reset” option using the volume buttons and confirm with the Power button. After the reset completes, check if the black screen issue is resolved.
What should I do if none of these solutions work?
If you have tried all the suggested solutions and the black screen issue persists, it may indicate a more serious hardware problem, such as a damaged display or internal components. In such cases, it’s best to seek professional help from a certified technician. They have the expertise required to diagnose and repair hardware issues accurately.
Avoid attempting to fix hardware problems on your own, as this can potentially make the situation worse. Visiting a professional will ensure that your device gets the appropriate care and restoration it needs.
