If you own a Galaxy S7 device, and you start the device with a black screen on it and there is no response from the device even when you press the device’s power button, then you are having a problem with the start-up from the device.
Several days after the release of the Galaxy S7, few owners started to complain about the device saying that the device won’t turn on. Well, if you are the one who is having the similar issue, you’ve come to the right place where you can get the information about why your device has such error and how to troubleshoot it.
First, let’s begin with the problem itself and why is it happening. Many of the users say that in several days after they bought their Galaxy S7, they face an issue where their screen is pitch black and it looks like the device is turned off. The device also is not giving any response after you click up the power up button, or even trying with charging. So, what could be the symptoms and what could cause such issue of the device.
Galaxy S7 Black Screen – What are the problems and symptoms
The symptoms could be next:
If the LED indicator is turned on, but the screen is still black and unresponsive
Screen is pitch black, the LED indicator is not turned on and the phone is not turning on if the power button is pressed
You hear notification sounds, but the screen still remains black
The device is turning off by its own and refusing to turn on back again
Even though these symptoms are common to all smartphones, there are some who encountered their issue by doing the following:
The battery is completely drained off, that may take some time for the device to respond to the charger when it is plugged in
There might be a system crash of the Android software that leaves the device unresponsive when you do whatever action on the device
Some of the apps that you downloaded might block the device and making it crash, even taking damage on the system itself
The power button might have suffered heavy damage if you ever dropped your device on a hard surface
By knowing this kind of issues, you can try to troubleshoot your device by yourself, and check which solution will help you with your issue.
Galaxy S7 Not Turning On – Solutions
So, let us begin with a step-by-step troubleshooting:
Fix 1: Force Restart Galaxy S7
The First Step that you can do, is to force restart your Galaxy S7. You can do this by pressing and holding down the Volume down and Power key button at the same time for 10 seconds. That will force your device to simulate a battery disconnection.
This procedure will be only working if you are doing it correctly. With this procedure also, you can refresh the phone’s memory, and with that, you can reset whatever hardware firmware or hardware glitch that occurred.
Fix 2: Plugin Galaxy S7 to Charger
Now, in the Second Step, if you failed the first one, you can try to plug in your device to charge. Seriously though, your device might be facing the issue of not turning on for a while, because of the reason that the battery had a complete drain off. So, if you put it on the charge, and leave it for a while, it might fix the issue.
Or just, you can wait up for 5 minutes after you put the device on charging, and then to try to turn on. After that, you can try the first step again.
Fix 3: Start Galaxy S7 in Recovery Mode
The Third Step that you can do, and of course if the first one and the second doesn’t work for you, you can see if your device can boot in Recovery Mode. By entering the recovery mode and following that procedure, we can see whether the device has a firmware issue or some serious hardware problem.
If the phone boots up in Recovery Mode, that means that the problem is within the firmware probably. Otherwise, it means that it is a hardware problem.
You can enter the Recovery Mode on your device by following the steps below:
Press and hold down the Home and the Volume Up button, and right after that press the Power button
After you see the Samsung Galaxy S7 logo, release the Power button, but continue to hold the Home and Volume Up buttons.
Finally, after you see the Android logo, you can release both keys and leave the phone for some 30 or 60 seconds.
If the device lets you go in Recovery Mode, and you finally enter it, you can continue to wipe out the cache partition by using the Volume Keys and Power button to navigate in the menu.
If this doesn’t work as well, you can proceed to the LastStep.
Fix 4: Boot Galaxy S7 in Safe Mode
In the Fourth Step, you can try to boot your device the Galaxy S8 in safe mode. Your device might have the issue of not turning on because it was caused by a third-party app that caused crash on your Android Operative System. In this case, you need to boot your device in Safe Mode to see if it can actually enter it, and see if there is truly a hardware problem.
You can enter the Safe Mode on your device by following these steps:
Press and hold down the Power button
After you see the Samsung Galaxy S7 logo on the screen, release the Power button and immediately hold the Volume Down button
Continue to hold down the Volume Down button until your device reboots itself
You can release the Volume Down button when you see the Safe Mode in the bottom left corner of your screen
If you successfully enter the Safe Mode on your device, you can continue and uninstall any suspicious apps. There is also another option where you can do Factory Reset by heading to the Settings, or, you can make Master Reset by booting the device in Recovery Mode again.
By doing either Factory Reset or Master Reset, any of these procedures will help you fix your issue. If these resets don’t work though, you can finally head up to the Last Step.
Fix 5: Take Phone to Samsung Custome Care
The Last Step is to give your device to a technician to troubleshoot the problem or just replace your device if the problem is not fixable. After you try all of the Four Steps from above, and still you don’t see your issue fixed, all that is left from you is to just simply head it over to a technician.
You should also be aware of the warranty of your device, because if it still has warranty, the technician will be able to replace your device even if he cannot fix your problem.
