The #Samsung Galaxy S6 Edge (#S6Edge) black screen of death is one of the most dreaded power-related issues with this device. It has been bugging a lot of users since the phone was released last year up until today. It’s called the “black screen of death” because usually the device’s display turns black or blank and won’t respond to touches. The phone itself also becomes dead when it occurs and it may not even charge when plugged in.
There are a couple of problems I addressed in this post that may seem similar. Read on to understand more about them and to learn how to fix each one of them. You may encounter similar issue in the future so it’s better to be ready and know what to do when the problem actually happens. Click on the links below to jump to their respective sections.

Problem: Hello. I have a Galaxy S6 Edge. I have left the phone overnight to charge. The phone is non-responsive this morning but the green light is flashing. I have tried the centre button with the volume up key and with the volume down key and all three power centre and volume key but no response from the phone … any ideas?
Troubleshooting: Hi! After the release of Samsung Galaxy S6 Edge, despite the device’s advertised features and great performance, it is still prone to some issues from software to hardware. Among the problems you may encounter are the power issues, like what you are experiencing right now. Since the phone has a non-removable battery, we can’t immediately rule out if it’s a battery failure since you said that the green led light is flashing it is the indication that the battery is full charge.
There are several reasons why this issue occurs but identifying the culprit is somehow complicated especially if you don’t know what caused it or when the issue started. But don’t worry we will recommend some methods that we shared to several owners that encountered similar issues.
Step 1: Force Reboot your phone to see if you can bring it back to life
The Galaxy S6 Edge doesn’t have a user-removable battery so you cannot just do the battery pull procedure to refresh its memory like we used to do with our old device. There is, however, another way to do this and that’s the Forced Reboot procedure. You just have to press and hold the Volume Down and Power keys together for 10 seconds. There is a higher probability this method will work, so it’s worth trying. Besides, it’s the most logical procedure you can do at this point.
If the procedure fails, however, then follow the next few steps.
Step 2: Run the Device in Safe Mode
If this issue is caused by a third party application that was installed on the device, then booting in safe mode will disable everything third party and it’s the best way to identify which of them is causing the problem. Once you’ve determined the culprit, uninstall it. Here’s the step-by-step instructions on what you should do…
- Make sure the device is off
- Press and hold the ‘Power key’ + ‘Volume down key’ together, wait until the Samsung logo appears.
- Quickly release the ‘Power key’ if the Samsung logo appears but continue pressing ‘Volume down key’.
- Wait until the device finish the process, it will take a few minutes.
- When you see the ‘Safe mode’ at the lower-side side of the screen, this means that safe mode is activated.
- Uninstall the problem-causing app and do not install it again to avoid the problem from happening again.
It would be easier to fix the problem if you’ve already have some suspects. So, begin your search from your latest or most recent app installations. There are of course apps that you couldn’t just uninstall as you will lose some of your data. In this case, you just have to disable them to prevent them from running when the phone boots up. After you’ve uninstalled or disabled them, reboot your device normally to see if the problem got fixed. If so, then one of those apps you’ve disabled or uninstalled is the culprit. For those you’ve disabled, try enabling them one by one and if the problem occurs while you’re doing that, then it’s now easier to determine the culprit. You may also re-install apps you’ve uninstalled but just be mindful of each installation.
Step 3: Run the Device in Recovery Mode and wipe cache partition
Recovery mode is similar to safe mode but, in this mode there are options for you to run some diagnostic test or reset the device. In this mode also we can go back to the default setting of your phone before the issue occur. Below are the steps on how perform this mode.
- Turn off the phone completely
- Press and hold the ‘Power key’ + ‘Home key’ + ‘Volume up key’ together
- Release the ‘Power key’ when the device vibrates but continue pressing ‘Home key’ and ‘Volume key’
- Wait until the Android mascot appears, then release both keys
- Navigate using ‘Volume Up and Down key’ through the options
- Select ‘wipe cache partition, press Power key to confirm.
- Wait until your device finish the process, it will take several minutes.
Wiping the cache partition will delete the system cache as well as temporary files created by pre-installed apps and native services. While the term is “delete” it doesn’t mean you’ll lose your data and important files. Only the system caches will be deleted and it may even result to a better performance as the system will create new files to replace deleted caches. If this procedure fails, however, then you have to reset the device to bring it back to its default settings or a configuration that works.
Step 3: Factory Reset the Device
This method is, sometimes, the last resort to resolve any software issues or power problems like what you have right now. But performing this procedure will delete all the data saved in the device and restore it back to the default setting the first time you got it. So, you better backup your files and data first and then follow these steps:
- Turn off the device
- Press and hold ‘Power key + ‘Volume up key’ + ‘Home key’ simultaneously
- Wait until the Android mascot appears then quickly release ‘Power key’ and continue holding ‘Volume up’ and ‘Home key’
- Once the boot menu displays, release both keys
- Navigate using Volume up and down key through options
- Find and select ‘Wipe Data/Factory Reset’ option, press Power key to confirm
- Next, select ‘Yes–delete all user data’ option, press Power key to confirm
- Wait until the device finish the process, it will display ‘Data Wipe Complete’
- Select ‘Reboot system now’, press Power key to confirm
- Restart will take longer than the normal restart, please be patient
Now, if these methods are not working for you, we recommend finding the nearest Samsung service center and have the device checked by a technician.
Problem: I just can’t understand why phone won’t respond anymore. I’ve taken care of this device since I bought it in December. It never fell and never been in contact with water. The screen is black and no matter what I do, it just won’t turn on or respond. What do you guys suggest I do to make my phone work again? Thanks.
Troubleshooting: It’s always possible that this problem is the same as the previous one and if it is then you can just follow the troubleshooting procedure. So, the first thing we have to do is verify if your problem is the same as the one I addressed above.
Step 1: Call your own number to see if the phone rings
In the first problem, the phone still lights up the LED indicator so there is a greater probability only the screen is turned off but the phone is still up and running. In your case, if the phone rings when you call your own number, then it means the phone is still powered on and only the display has an issue. So, you can follow what I suggested–forced reboot. You may be able to fix the problem as early as now provided it’s the same as the first one. However, if it’s a different case, then continue with your troubleshooting:
Step 2: Plug the phone to charge
The battery may have been drained that’s why the phone won’t respond nor turn on. With this, the device will be able to replenish the battery even for just a couple of minutes. That would be enough to power the phone up and all its components. Aside from that, you’re also trying to find out how the phone reacts if it detects current flowing through its circuits. If it won’t charge nor respond, then it might be a problem with the hardware itself but continue troubleshooting.
Step 3: Force reboot the phone while plugged in
You already did the forced reboot procedure in step 1 but the firmware may have crashed and the battery drained. So, let’s rule out those possibilities out in this step; while the phone is plugged in, press and hold both the Volume Down and Power keys together to see if the phone boots up. If not, try the next step.
Step 4: Attempt to boot the phone in safe mode
Third party apps may have caused the problem so try to boot the device in safe mode. If it does boot up, then problem solved. You just have to find the app that’s causing the problem and either disable or uninstall it. Here’s how you boot your phone in safe mode:
- Press and hold the Volume Down and Power keys for 20 to 30 seconds.
- Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
- Your phone should continue booting up and you will be prompted to unlock your phone as usual.
- You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.
Step 5: Try booting it in Recovery Mode
This procedure will sort of disable the Android interface so if the problem is with the frontend, then the S6 Edge should reboot without any problem at all and in this case continue with the wiping of the cache partition. If it doesn’t, you have no other choice but to have it checked by the technician. Here’s how you boot the phone in Recovery Mode.
- Turn off the device.
- Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
- When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
- When the Android System Recovery screen appears, release the Volume Up and Home keys.
- Press the Volume Down key to highlight ‘wipe cache partition.’
- Press the Power key to select.
- When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
I hope this helps.
