Power-related problems are among the most commonly reported issues with the Samsung phone like the Galaxy S8 with the Black Screen of Death (BSoD) being at the top spot.

This issues may occur due to minor firmware glitch or crash, some apps may have crashed and affected the phone’s performance and resulted to a system crash, a recent update may have corrupted some of the system caches and files and resulted to inconsistencies, and lastly, it might be due to physical and / or liquid damage. 

Unlike the real power issue wherein the phone is totally turned off and won’t respond when you press the Power key or connect to its charger, the BSoD may leave the phone powered on with all other hardware components working properly except the screen or the display.

One sign to immediately know if it’s BSoD or not is when the phone sounds off when messages or calls are received or the LED notification light may flash every now and then. If you’re one of the owners of this phone and are currently bugged by a similar issue, a simple soft reset may not work in fixing the problem.

What Causes an Android Black Screen?

Unfortunately, there’s no one single thing that can cause your Android to have a black screen. Here are a few causes, but there could be others, too:

• The screen’s LCD connectors may be loose.
• There is a critical system error.
• You may have installed incompatible apps.
• The phone may have been overcharging for a long period of time.
• There are app caches that need to be cleared.
• The phone has been exposed to extreme heat (such as leaving it in a hot car).

Complicated as it may seem, this problem is actually very easy to fix provided that the black screen is not due to physical or liquid damage. To fix this, this is what you have to reset your Samsung phone by:

• Press and hold Volume Down and Power keys together for 10 seconds.

This procedure is what we call Forced Restart. It simulates battery disconnect which the same effect as when you pull the battery out of the phone with removable power source. The device’s memory will be refreshed and that should be enough to bring the dead phone back to life provided the cause of the problem is just a system crash. However, if this fails to fix the problem, try doing this…

1. Step 1. Press and hold the Volume Down button and don’t let go of it.
2. Step 2. Press and hold the Power key while holding down the Volume Down button.
3. Step 3. Keep both keys held down for 10 seconds.

It basically has the same effect as the first procedure only that you press and hold the Volume Down button first before triggering the phone to power up by pressing the Power button. Bear in mind that if the Power key is pressed first, the phone would immediately react to it because it’s hard-wired to do so.

When that happens, the Volume Down and Power combo will never be done correctly so the phone may not turn on since pressing and holding the Power key couldn’t do something about a firmware crash.

If this fails as well, then it’s possible the battery has been totally drained. So try doing this…

Step 1. Plug the charger to a working wall outlet.

Step 2. Connect the phone to its charger using the original cable.

Step 3. Allow the phone to charge for a few minutes regardless whether the charging symbol shows or not.

Step 4. After which, press and hold the Volume Down button and the Power key together for 10 seconds.

After doing all these procedures and your Galaxy smartphone is still not turning on, then the problem isn’t just one case of system glitch or crash. You have to do some troubleshooting procedures to see if you can fix this issue without going to the service center.

Why Did my Samsung S21 Screen go Black?

The black screen of death issue may occur every now and then even on premium phones like the Galaxy S21, but it does not necessarily mean it’s serious. Most of the time, it’s just due to a pretty minor firmware-related problem that you can fix on your own. With that being said, here’s what you should do about it:

Force restart your phone

If your Galaxy S21 shut down and would no longer respond for no apparent reason, then it’s probably just due to a firmware crash. There are times when Android just stops working and may leave an impression that your phone has a hardware problem because it would no longer power on. But don’t worry, such an issue can be fixed. What you need to do is the forced restart. Here’s how it’s done:

1. Press and hold the Volume Down button and the Power key for 10 seconds. This often forces an Android device to boot up. 
2. If the logo shows, release both keys and allow your device to continue the boot process. 

If you can make the logo show, then the problem is fixed. However, if your Galaxy S21 remains to be unresponsive, then you have to do the next solution. 

How can I Fix my Samsung A10 Black Screen?

With that said, here’s what you should do to try and fix this problem…

Perform the Forced Restart to fix the black screen issue

If this is just a problem caused by a system crash, then this procedure will definitely make your phone respond again. The Forced Restart is a simulated battery removal that will force the phone to turn off and turn back on again. Here’s how it’s done on your Galaxy A10: 

1. Press and hold the Volume Down button and don’t release it yet. 
2. While holding down the volume button, press and hold the Power key as well. 
3. Keep both keys held down together for 15 seconds or until the Galaxy A10 logo shows on the screen.

If you were able to make your Galaxy A10 show the logo, that’s a sign that the phone is actually responding.

However, if the device still won’t respond to this procedure or if it responded but turn back off again, then move on to the next solution. 

Second solution: Charge your phone and do the forced restart

At this point, it’s possible that the battery of your phone has been completely depleted and while it’s not really a big issue, there are times when it would lead to a system crash. When that happens, you will be dealing with a couple of pretty minor issues that both result in an unresponsive phone or the black screen of death issue. But don’t worry, there’s always something you can do about it. Here’s how: 

1. Plug the charger to a working wall outlet. 
2. Using the original cable, connect the phone to its charger.

5. While holding down the volume button, press and hold the Power key as well. 
6. Keep both keys held down together for 15 seconds or until the Galaxy A10 logo shows on the screen.

If you were able to make your phone respond again after doing any of the procedures I cited, then the problem was all with the firmware. However, if the occurs every now and then, then you would need to reset your phone to ultimately fix the problem. 

Before you do the reset, create a copy of your important files and data and then remove your Google account so that you won’t be locked out. When ready, follow these steps to reset your phone: 

1. Turn off the device.
2. Press and hold the Volume Up and Power keys.

In the event that your phone’s screen will not shut off, or it shuts off all the time, you may be correct to blame the proximity sensor. Before disabling your proximity sensor, however, the best troubleshooting step is to first clean your phone.

Clean Your Phone

Step 1

Turn off your phone and blow into the speaker with compressed air.

Step 2

Ensure there is no debris or dust in the speaker of your phone. If necessary, use a toothpick or other implement to carefully remove debris.

Step 3

Restart your phone and test the proximity sensor functionality of your phone. It has been noted that dust and debris in this area of your phone is the common culprit for a malfunctioning proximity sensor. The proximity sensor is located at the top of your phone and if you hold the screen at a slight angle, you can see the sensors. They look like small holes covered by the screen glass and are close to the speaker.

Disable the Sensor

Step 1

Tap the “Phone” icon on your phone to open the Phone app. Then tap the “menu” button and select “Settings” or “Call Settings.”

Step 2

Disable the proximity sensor setting in this menu. The procedure and tools may vary depending on the model of phone you own and which version of Android you have. Older versions of Android may not allow the same access to hardware functions as newer firmware versions.

Step 3

Retest your phone during a call. If you have disabled the proximity sensor, the screen should not turn off when you hold it close to your face or if you place your hand close to the screen during a call.
