What to do when your Samsung Galaxy S8 shows the Black Screen of Death [Troubleshooting Guide]

The Black Screen of Death (BSoD) is one of the most dreaded problems that plagued many smartphone owners and you may encounter it with your new Samsung Galaxy S8. We find it necessary to publish this post that basically addresses the black screen issue to, at least, give you a better idea what to do when the problem happens.

Just because the screen is black and unresponsive doesn’t mean the phone is dead already. It might have just crashed for some unknown reason and waiting for you to do something to spring back to life. The black screen issue may occur any time regardless of the condition of your phone. Usually, the device won’t respond no matter how many times you press the power key. It may not even respond when charged.

The BSoD is different from the issue wherein the phone refuses to turn on for the first time because the latter may be a sign of a manufacturing defect. The former, however, could be a sign of a hardware failure caused by other factors after you’ve used your phone for a few days. Among the most common factors are liquid and physical damages.

In this post, I will walk you through in troubleshooting your new Samsung Galaxy S8 that’s plagued with the black screen of death problem. So, continue reading below to know about about this issue.

But before anything else, if you’re currently experiencing different issues with your phone, then I suggest you visit our Samsung Galaxy S8 troubleshooting page for we’ve already started providing support to our readers who own this device.

Troubleshooting Galaxy S8 with Black Screen of Death (BSoD)

I understand your phone is still new and it should work properly without any issues but here we are trying to find out what’s the reason behind this problem. Basically, the purpose of this troubleshooting is for us to know if the problem is minor and can be fixed easily or if you really have to go back to the store and have the device replaced.

While the BSoD is a serious problem, we’ve already encountered a lot of issues before that posed as this kind of issue but in the we were able to bring the devices back to life. That’s what we have to try here and said, here’s what you should do:

Step 1: Force reboot your Galaxy S8 to rule out possibility of a system crash

The first thing we have to assume is that the phone’s firmware crashed for some unknown reason. This thing happens all the time and we’ve seen hundreds of issues like this in the past only to find out that many of there were a result of a glitch. Before, we usually remove the battery and press the power key for a minute so that phone’s memory would be replaced but since your Galaxy S8 has a non-removable battery, we cannot do that anymore. However, there’s one combo that will do the simulated battery disconnect and that would be enough to fix this problem provided it’s just as simple as a system crash or a glitch.

Press and hold the Volume Down button and the Power key together for 7 seconds and the phone may reboot normally. If it does, then the problem is fixed, otherwise, you must move on to the next step to probe further.

Step 2: Try to charge your phone to see if it responds

We surely want to know if your phone would still respond if it detects electric current flow through its circuits. If it displays the usual charging icon as well as light up the LED indicator at the top of the screen, then we can, at least, say the hardware might be fine because if not, then it shouldn’t charge at. However, if the phone doesn’t show those signs, then do the forced reboot procedure while the device is plugged in; its battery may have just been drained completely that there’s not enough battery to power up its hardware and load the operating system. If it still won’t power up with it, then it’s time to seek assistance from a tech.

On the other hand, if the phone charges fine or shows those signs, then leave it plugged in for ten minutes. That should be enough to reach around 5% of battery or even more. After which, attempt to turn the phone on to see if it does respond. If not, then do the forced reboot procedure once again and if it still won’t respond, move on to the next step.

Step 3: Try booting your phone up in safe mode to rule out possibility that third-party apps cause the problem

Third party apps can also cause the system or the firmware to crash especially ones that use too much resources like heavy games. The problem is we don’t know for sure which app is causing the problem. Therefore, we need to do something to isolate third-party from built-in apps and booting in safe mode is the best you can do:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.

By following the steps above, you are temporarily disabling all downloaded apps and third-party services. Therefore, if one or some of them is causing the problem, the phone should boot up in safe mode successfully. If it fails, however, then move on to the next step.

Step 4: Attempt to boot your phone up in Recovery mode

The phone got a black screen and won’t respond to whatever it is you do. You’ve just tried to boot it up in safe mode and it failed, so now, it’s time to try to boot it up in another mode, the Android system recovery. We just have to know if it’s still capable of starting up in that mode to find out if the hardware is fine or not. Follow these steps to attempt to start it up in recovery mode:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).

If successful, then we’re already halfway there; at least the phone is capable of powering up its hardware components and loading up its firmware. You can then proceed to wiping the cache partition so that system caches will be replaced or you may opt to doing the master reset. However, if the phone still failed to boot up in recovery mode, then you have no other option but to bring the phone back to the store and have it replaced as it is clear enough there’s something wrong with it.
