A quick fix to the black screen of death issue on Galaxy S7 Edge

Here’s one of the problems we received from our reader that best describes what the black screen of death is and how it occurs…

Problem: I have a Samsung Galaxy S7 Edge. It has been freezing a lot lately then this evening it froze then the screen went black but the touch screen buttons at the bottom have remained lit the whole time. I have tried your reboot instructions and nothing has happened, it has been like this most of the day. Please help!

The most common reason that your phone screen went black is due to system crashing. The fact that the hardware buttons are lit up means the hardware components are all fine and this might be just a minor software-related issue. The good thing is you can resolve this problem on your own without bringing your phone to the tech and spend money for repair. Here’s the solution that we know works for this problem, I hope it works for you, too.

Solution: Do the Forced Restart procedure to refresh your phone’s memory. It’s basically has the same effect to the battery pull procedure we often do to phones with removable batteries. To do this press and hold the Volume Down button and the Power key simultaneously for 10 seconds.

Provided the hardware is fine and there’s enough battery left, your phone should boot up normally after doing this. If it doesn’t, try pressing and holding the Volume Down button first and without letting go of it, press and hold the Power key as well. Keep both keys held for 10 seconds or until the phone turns on. After this and the phone is still unresponsive, then we have to do some troubleshooting procedures.

Troubleshooting Galaxy S7 Edge with black screen of death

The following are the most basic troubleshooting procedures. They’re effective in dealing with minor issues but when it comes to hardware problems, only the tech who can perform tests on your phone have a shot at fixing them. If you’re not comfortable doing the following procedures, then bring your phone to the tech already. However, if you’re one of the owners who want to tinker their phones, then read on…

Make sure that it’s not just a drained battery

Through charging, we make sure that there’s enough power stored in the battery so that the device can power on when you press the Power ke. If the battery is drained, that could be the reason why your phone won’t boot up no matter what you do.

Try to connect your phone to its charger and let it charge for 10 minutes and observe if it is responding. If not, there is a possibility that the battery is defective and you don’t have a choice but to replace it for a new one. But the thing is you really can’t do something about that since your phone has a non-removable battery. So the best thing you can do is bring the phone to the tech to have it checked. Before you do that, I suggest you do following procedures first to see if the phone won’t respond to them.

Restart your phone in Safe mode

We usually suggest to our readers to boot their phones in safe mode to determine if the problem is due to a third-party app that has gone rogue or started malfunctioning. This time though we just want  you to boot your phone in this mode to know if it’s capable of doing so. The moment the phone boots up in this environment, you can consider the problem fixed and the next thing you need to do is find the app that’s causing the problem and uninstall it.

Here’s how you boot your phone in safe mode…

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 EDGE’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

And this is how you uninstall an app…

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap the desired application in the default list or tap Menu icon > Show system apps to display pre-installed apps.
  5. Tap Uninstall.
  6. Tap Uninstall again to confirm.

If the phone still refuses to boot up in this mode, then try the next method.

Attempt to boot in Recovery mode

The Android system recovery is the fail-safe of all Android devices. Provided there’s no serious problem with the hardware and that the battery has a charge left, your phone would be able to turn into this mode regardless whether it’s suffering from a serious firmware issue or not. Once the phone boots into this mode, wipe the cache partition and wait for the phone to boot up. But the moment the phone enters this mode, the problem is already fixed because the phone already turned on. So the issue will be downgraded to a booting problem, which is easier to fix than the former. This is how you run your phone in recovery mode and wipe the cache partition.

  1. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  2. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  3. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  4. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  5. Once highlighted, you may press the Power key to select it.
  6. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  7. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  8. The phone will now reboot longer than usual.

Assuming you’ve successfully started the phone up in this mode and wiped off contents of the cache partition but the phone failed to boot up successfully, then you will have to do the Master Reset and this is how you do it:

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key. NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds. NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

I hope that this troubleshooting guide can help you but if the phone is still unresponsive or can’t boot up in recovery mode, then it’s the perfect time to seek assistance from the tech. Bring your phone to the service center as it’s probably an issue with the hardware.
