In this comprehensive guide, we’ll walk you through the steps to diagnose and fix the black screen issue on your Samsung S21, along with insights into preventing future occurrences.
Understanding the Samsung S21 Black Screen Issue
Before diving into the solutions, it’s essential to understand what might cause the dreaded black screen on your Samsung S21. The black screen issue can arise from several factors, including:
- Software Glitches: Updates or apps that fail to function properly can lead to temporary software issues.
- Hardware Problems: Faulty components, such as a damaged display or an exhausted battery, can also be significant culprits.
Understanding the root of the problem is crucial to effectively addressing it. Let’s explore various solutions you can try to fix your Samsung S21’s black screen.
Initial Troubleshooting Steps
When faced with a black screen, the first step is to perform some basic troubleshooting techniques that don’t require advanced technical skills. These methods are quick, often effective, and can save you from lengthy repair processes.
Force Restart Your Galaxy S21
A simple force restart can resolve many software-related issues. It’s an essential first step in troubleshooting a black screen.
How to Force Restart
- Press and hold the Volume Down and Power buttons simultaneously.
- Continue holding both buttons for about 10 seconds until the Samsung logo appears.
- Release the buttons; your device should reboot.
A force restart clears temporary glitches that may be causing the black screen.
Charge Your Device
Sometimes, the issue stems from a depleted battery. If your phone isn’t charged, it might appear to be stuck on a black screen.
Charging Steps
- Connect your Galaxy S21 to a charger using the original charging cable.
- Allow it to charge for at least 15-30 minutes.

Samsung experts can accurately diagnose your device and provide repair options for both hardware and software problems.
Preventing Future Black Screen Issues
Once you resolve the black screen issue, consider implementing preventive measures to reduce the likelihood of it occurring again.
Software Updates
Regularly check for software updates to ensure your device runs smoothly. Updates often contain essential bug fixes and performance improvements that can minimize issues, including the black screen.
How to Check for Software Updates

What causes the black screen issue on my Samsung S21?
The black screen issue on your Samsung S21 can be caused by a variety of factors. Common culprits include software glitches, outdated firmware, or a problematic app. It’s also possible that physical damage, such as a cracked screen or water exposure, may be affecting your device’s display. Understanding the root cause is essential in determining the right troubleshooting methods to employ.
In most cases, the issue arises from software-related problems that can be resolved with a simple restart or system update. However, if these quick fixes do not work, further diagnostic checks may be required to rule out hardware issues. Always ensure that your device’s software is up to date to minimize the chances of encountering such problems.
How can I perform a soft reset on my Samsung S21?
Performing a soft reset on your Samsung S21 is a straightforward process that can often resolve minor issues like a black screen. To initiate a soft reset, press and hold both the Volume Down and the Power buttons together for about 10 to 15 seconds. This action forces the device to restart, and it may help restore the display functionality.
After the phone restarts, check to see if the black screen issue persists. In many cases, a soft reset can resolve temporary software glitches. If the screen remains black, you may need to consider other troubleshooting methods or further diagnostics to identify the problem.
What should I do if my screen remains black after a restart?
If your Samsung S21’s screen remains black even after performing a soft reset, there are several additional steps you can take. First, try charging your device for at least 30 minutes to ensure that it is not simply a battery issue. A depleted battery can sometimes cause the screen to turn black and may not respond immediately after charging.
If charging does not resolve the issue, consider booting your S21 into Safe Mode. This mode disables third-party applications that may be causing conflicts. To enter Safe Mode, hold down the Power button, then tap and hold the “Power off” option until you see the prompt for Safe Mode. If the screen works in Safe Mode, an app is likely the cause of the problem, and you may need to uninstall recently added apps.
Is there a way to reset my Samsung S21 without a display?
Yes, you can reset your Samsung S21 without a display by using hardware buttons. This process is known as a factory reset, which can help if the black screen issue is due to persistent software problems. First, make sure your device is powered off. Then, press and hold the Volume Up and Bixby buttons, along with the Power button simultaneously. Once you feel the device vibrate, release the buttons, and you should enter recovery mode.
In recovery mode, use the Volume buttons to navigate and highlight the “Wipe data/factory reset” option. Confirm your selection with the Power button. Please note that this process will erase all data on your device, so it’s advisable to back up any important information beforehand. If the screen remains unresponsive even during this process, hardware issues may need to be explored.
Can a screen protector cause the black screen problem?
While it’s uncommon, a poorly fitted or damaged screen protector can contribute to display issues on your Samsung S21. If the screen protector is affecting the touch sensitivity or lifting off at the edges, it might cause the device to exhibit erratic behavior, including a black screen. If you suspect that your screen protector might be the culprit, it’s worth removing it and testing the phone without it.
If the removal of the screen protector does not resolve the issue, then the problem likely lies elsewhere—such as in the software or hardware of the device itself. Always screen your device for signs of damage, as a compromised screen may require professional repair or replacement to restore functionality.
What should I do if my Samsung S21 is still under warranty?
If your Samsung S21 is still under warranty and you’re experiencing a persistent black screen issue, it’s recommended to contact Samsung support or visit an authorized service center. Warranty services typically cover hardware defects, which may include display problems that cannot be resolved through basic troubleshooting. Make sure to provide any relevant information regarding the issue, including steps you have already taken to try and solve it.
When visiting a service center, bring your proof of purchase and the warranty documentation if required. Technicians will perform a thorough diagnosis and repair or replace your device as necessary, ensuring that you’re not left dealing with a malfunctioning phone for long.
Are there any third-party solutions to fix the black screen issue?
There are several third-party applications and services that claim to fix software-related issues, including black screen problems on smartphones. However, exercising caution is essential when using these solutions, as they can sometimes lead to additional complications or void your warranty. Always research the reliability and credibility of any third-party software before downloading or using it; it’s wise to stick to well-reviewed and well-known services.
In many cases, the most effective solutions for black screen issues are those provided by the manufacturer or authorized technicians. If you prefer not to use a third-party option, consider leveraging the troubleshooting methods outlined previously, or get in touch with Samsung support for guidance.
