Understanding the Black Screen Issue
When your Samsung S21 Plus displays a black screen, it might seem like the device is dead. This issue can arise due to various reasons, including software glitches, hardware failures, or even battery problems. Identifying the root cause is essential for effectively addressing the issue.
Common Causes of Black Screen on Samsung S21 Plus

- Dead Battery: If your battery is completely drained, the screen will not turn on.
- Physical Damage: Drops or spills can lead to hardware damage, resulting in a black screen.
- Overheating: Extended usage or running multiple applications can cause your phone to overheat, leading to a screen blackout.
- Faulty Software Updates: Sometimes, new software updates may not install correctly, leading to black screen issues.
Basic Troubleshooting Steps
Before delving into more complex solutions, it’s crucial to perform some basic troubleshooting steps. These can often resolve minor issues quickly.
Check the Battery
Before assuming the worst, ensure that your Samsung S21 Plus has enough power.
- Plug the device into a charger for at least 30 minutes.
- Look for any charging indicators, such as vibration or a charging icon.
If the device shows signs of charging, let it charge fully before attempting to turn it on again.
Force Restart Your Device
A simple force restart can solve many software-related issues. Follow these steps:
- Press and hold the Volume Down button and the Power button simultaneously.
- Keep pressing both buttons until the device vibrates and the Samsung logo appears (approximately 10 seconds).
This action can often reset temporary software bugs that may be causing the black screen.
Advanced Solutions to Fix Black Screen

Booting into Safe Mode can help determine whether third-party applications are causing the problem.
- Press and hold the Power button until the power menu appears.
- Tap and hold the Power Off option until you see the Safe Mode prompt.

Clearing the cache can address software-related issues and improve overall performance.
Factory Reset as a Last Resort
If all else fails, a factory reset may be necessary. This will erase all data, so ensure you back up anything important before proceeding.
How to Perform a Factory Reset

Conclusion
Experiencing a black screen on your Samsung S21 Plus can be frustrating; however, with the right steps, you can often fix the issue on your own. By following the troubleshooting steps outlined in this article, you can effectively diagnose and potentially resolve the problem.

With proper care, you can enjoy your Samsung S21 Plus without the fear of unexpected black screens.
1. What causes the black screen issue on the Samsung S21 Plus?
The black screen issue on the Samsung S21 Plus can be caused by a variety of factors. One common reason is a software glitch, which may occur after a system update or an app installation. Another possibility is hardware-related issues, such as a malfunctioning display, a damaged screen, or problems with internal components.
In some cases, the black screen may be a result of the device going into sleep mode or an accidental drop. It’s also important to consider external factors like battery drain, as a low battery can prevent the phone from turning on or display any visual output. Understanding the underlying cause can help you apply the right fix.
2. How can I perform a soft reset on my Samsung S21 Plus?
Performing a soft reset on your Samsung S21 Plus is a straightforward process that can resolve temporary glitches. To do this, press and hold both the Volume Down and Power buttons simultaneously for about 10 to 15 seconds. This action will force the phone to restart, which can help restore functionality if the black screen is due to a minor software issue.
After the reset, wait for the device to restart fully. If the screen remains black post-reset, you may need to explore other troubleshooting options or check for hardware issues, as a soft reset may not fix more serious problems.
3. What is Safe Mode, and how can I access it on my Samsung S21 Plus?
Safe Mode is a diagnostic mode on Android devices that allows you to run the system without third-party applications. Accessing Safe Mode can help determine if a recently installed app is causing the black screen issue. To enter Safe Mode on your Samsung S21 Plus, press and hold the Power button until the Power off option appears. Then, tap and hold the Power off option until you see the Safe Mode prompt, and confirm to enter.
Once in Safe Mode, observe if the black screen problem persists. If the issue does not occur in Safe Mode, it’s likely that a third-party app is causing the conflict. You can then exit Safe Mode and start uninstalling recently added apps one by one until you identify the culprit.
4. What should I do if the screen stays black after charging my Samsung S21 Plus?
If your Samsung S21 Plus screen remains black even after connecting it to a charger, the first thing to do is to check the charging equipment. Ensure that your charger and cable are functioning properly and that there is no lint or debris in the charging port. If possible, try using a different charger or cable to see if it makes a difference.
If the screen still does not respond after confirming that the charger is working, a deeper issue might be at play. You may need to perform a soft reset or seek professional repair services if you suspect hardware damage or a severe software malfunction.
5. Can I fix the black screen issue myself, or should I seek professional help?
Many users can resolve the black screen issue on their Samsung S21 Plus through basic troubleshooting methods such as soft resets, safe mode, or battery pulls. These methods can effectively address software-related problems without the need for professional assistance. If you feel comfortable, you can start with these approaches before escalating to more complicated fixes.
However, if you have gone through these steps and still experience the black screen, it may be time to consult with a professional. Hardware issues, in particular, may require expert evaluation and repair to avoid further damage to the device. Seeking help sooner rather than later can save you potential repair costs down the line.
6. How can I recover my data if the screen is black and I cannot access my phone?
Recovering data from a Samsung S21 Plus with a black screen can be challenging, but it’s possible under certain circumstances. If your device is still operational but the screen is non-functional, you can use Samsung’s Smart Switch application to back up your data to a computer. Connect your device using a USB cable and follow the on-screen prompts to back up your files.
If the phone is completely unresponsive and Smart Switch doesn’t recognize it, recovery options may be limited. In such cases, you could consider reaching out to data recovery specialists who can access the internal storage more effectively. There are risks involved, and it can be costly, so always weigh the importance of the data against the potential expenses.
7. Can software updates help solve the black screen problem?
Yes, installing software updates can often resolve issues like the black screen on the Samsung S21 Plus. Software updates typically include bug fixes, performance enhancements, and security patches that can address glitches causing display problems. If your phone is accessible, go to Settings, select Software Update, and check for available updates to install.
However, if you’re unable to access the device due to the black screen, this option may not be feasible. In such cases, consider accessing recovery mode, where you can perform a factory reset or apply the latest software update via a computer using Samsung’s Smart Switch or Odin software. Keep in mind that a factory reset will erase all data on the device, so it should be a last resort.
8. Is there a warranty for fixing my Samsung S21 Plus with a black screen?
If your Samsung S21 Plus is still under warranty and the black screen issue is not due to user-induced damage, you should be covered for repairs. It’s advisable to check your warranty status through Samsung’s website or by contacting their customer support. If the device has a manufacturer defect, submitting a claim can potentially save you repair costs.
However, if the damage is due to accidental drops or liquid exposure, the warranty may not cover repairs. In such cases, Samsung offers various repair services, often at a charge, which could be less expensive than third-party repair shops. Ensure you weigh your options and review your warranty details before proceeding with repairs.
