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

This is an issue that may seem serious but actually a minor one especially if the black screen is accompanied by a flashing notification light at the top of the screen. We’ve encountered this problem countless times already and even now we still have readers asking for assistance as their phones stopped responding. This time though, we already know what works and what not so we can help them better than before.

So, if you’re one of the S7 Edge owners who are bugged by the black screen of death issue, this is what you’re going to do to fix this problem…

  • Press and hold the Volume Down button and the Power key simultaneously for 10 seconds.

This procedure is what we call Forced Restart and as the name suggests, it will force the phone to power on and boot up successfully. Assuming the problem is just a result of a system crash, as it usually is, then this procedure is very effective and you may continue using your phone in no time. However, if the phone won’t respond, then try this…

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

If your phone still won’t respond to this, it’s possible the battery is completely drained and the system crashed just before the it ran out. So, try this…

  1. Plug the charger to a working wall outlet.
  2. Connect your phone to it using the original USB / data cable.
  3. Allow the phone to charge for 10 minutes regardless whether it shows the charging signs or not for as long as it’s not heating up.
  4. Do the Forced Restart procedure again but this time while the phone is connected to its charger.

After exhausting all these options and your phone remains unresponsive, then you will have to troubleshoot it because the problem might have been caused by a serious issue in the firmware. Continue reading as I will walk you through on how to troubleshoot your Galaxy S7 Edge that won’t turn on.


How to troubleshoot Galaxy S7 Edge with a Black Screen of Death issue

You will only have to troubleshoot your phone if the solution I provided above didn’t fix the problem. However, if you are not comfortable doing some troubleshooting procedures on your phone, I suggest you bring it to the service center instead. But for those who are willing to do some troubleshooting procedures to try to fix the problem, then continue reading as one of the methods may help bring the phone back to life.

Check for possible physical and liquid damage

Had your phone been dropped on a hard surface or in water, then that could be the reason why it won’t turn on anymore. It doesn’t necessarily mean the entire phone is damaged, it could only be the display that has issues.

For physical damage, any force that will leave the phone useless should leave a mark on the outside. So, look for scratches, dents and cracks especially if you personally know the phone hit a hard surface. If the phone still looks flawless with minor scratches only, then it may be free from physical damage.

The S7 Edge is water-resistant so it won’t be easy for any sort of liquid to get into it but that doesn’t mean it’s not possible to have water damage. To check whether there’s liquid damage or not, try doing the following…

  1. Look into the USB or charger port to see if there’s a trace of water or any liquid.
  2. Use a cotton swab to clean around the area or you may insert a small piece of tissue into it to absorb the moisture if any.
  3. Check the Liquid Damage Indicator (LDI) to see if it’s tripped. It’s located in the SIM slot so you will have to remove the SIM card tray.
  4. If the LDI is white, there’s no liquid damage; if it turned red or purple, then the problem may be due to liquid damage.

After making sure there’s no physical and / or liquid damage, try doing the next step.

Try running the phone in Safe mode

By running the phone in this mode, you’re temporarily disabling all third-party apps which may have also caused the system to crash. Try rebooting your device into this mode just to see if it’s capable because if so, then you can consider this problem fixed.

  1. Press and hold the Power key past the Samsung Galaxy S7 edge screen.
  2. When “SAMSUNG” appears on the screen, release the Power key.
  3. Immediately after releasing the Power key, press and hold the Volume down key.
  4. Continue to hold the Volume down key until the device finishes restarting.
  5. Safe mode will display in the bottom left corner of the screen.
  6. Release the Volume down key when you see Safe Mode.

Assuming your phone actually turned back on in this mode, the next thing you should do is find the app that’s causing the problem and uninstall it.

  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 your S7 Edge however, doesn’t boot up in safe mode, then you have to try the next method in a bid to fix this problem.

Try starting the phone in Recovery mode

This is your last resort and if your phone cannot boot up in this mode, then you would really have to bring it to the service center so that the technician can check it up for you. It’s important that you try this procedure because if successful, you can try wiping the cache partition to replace all system caches. Or you may proceed with the Master Reset which will bring the phone back to its factory default settings.

How to boot S7 Edge in Recovery mode and wipe cache partition

  1. Turn off the device.
  2. Press and hold the Volume Up key, Home key, and Power key at the same time.
  3. When the phone powers on, the Android System Recovery screen appears approx. 30 seconds later.
  4. Release all of the keys.
  5. Press the Volume down key to highlight “wipe cache partition.”
  6. Press the Power key to select.
  7. Press the Volume down key to highlight “yes” and press the Power key to select.
  8. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  9. Press the Power key to restart the device.

Bear in mind that you would lose all your files and data that are stored in the phone’s internal storage.

  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).
  4. Press the Volume down key several times to highlight “wipe data / factory reset”.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, “Reboot system now” is highlighted.
  9. Press the Power key to restart the device.

If all else fails, then bring the phone to tech.
