We’ve already addressed issues in the past wherein the Samsung Galaxy S7 Edge reportedly shut itself down and refused to turn back on. Depending on how this problem started, it could be just a minor issue or a very serious hardware problem. The key to fixing the problem is to determine what caused it but what if the phone shut down on its own without any apparent reason or cause? In such case, you would need to troubleshoot your phone to know more about the issue.
In this post, I will walk you through in doing the solution that has been very effective in fixing this problem, at least, based on the report from our readers who have encountered this problem. As long as the phone hasn’t been dropped on a hard surface or got submerged in water for more than 10 minutes, then this problem is just one of those issues that can easily be fixed. So continue reading below to see if you can make your phone to turn on.
But before anything else, if you have another issue with your phone, drop by our S7 Edge troubleshooting page as we have already addressed hundreds of issues reported by the owners.

Solution to your Galaxy S7 Edge that won’t turn on
More often than not, when you find your phone powered off and would not turn on, it’s due to a system crash or a minor glitch in the system. If this is really the case, then you don’t have to worry so much about your phone because the problem can easily be fixed. How would you know if it’s just a system crash? If the phone turned off on its own or if it won’t turn on without apparent reason.
The most common situation is when owners discover their devices powered down with a black screen and won’t respond after being charged overnight. In this case, what you can do is this:
- Press and hold the Volume Down and Power keys simultaneously for 10 seconds or more.
When done correctly, it will bring the phone to boot up into the home screen successfully and this could be the end of the problem. The procedure is often called Forced Restart as it simulates battery disconnect which turns the phone off by cutting off the power source. It’s effective, easy to do and safe for your data and phone. However, if this doesn’t bring your phone to life, then try this…
- Press and hold the Volume Down button first and don’t let it go.
- Press and hold the Power key while holding down the Volume Down button.
- Keep both buttons held down for 10 seconds or until the screen turns on.
It’s the same as the first procedure only that we’re making sure you’re doing the procedure right by pressing and holding down the Volume Down button before triggering the phone to power on. If this won’t help either, then you should try this…
- Plug the charger to a working AC outlet.
- Connect your phone to the charger using the original cable.
- Allow the phone to charge for at least 10 minutes regardless whether the charging symbol shows or not.
- Attempt to turn the phone on or do the Forced Restart procedure again but this time while the phone is connected to its charger.
If the phone still refuses to turn on, then try the following troubleshooting procedures.
Troubleshooting Galaxy S7 Edge that shuts off and refuses to turn on
The following procedures will try to bring thep phone to boot up. You may not need to do complicated procedures to know if the problem is with the hardware or not. If your S7 Edge turns on or boots up in either of the modes, then that confirms that the problem is not with the hardware. So, try to see if you can make your phone to start with those…
Try to run the phone in Safe mode
This will temporarily disable all third-party apps so if the problem is due to an app or two that you downloaded from the Play Store, then your phone should boot up into this mode without much of a problem. Here’s how you do it:
- Turn the device off.
- Press and hold the Power key past the Samsung Galaxy S7 edge screen.
- When “SAMSUNG” appears on the screen, release the Power key.
- Immediately after releasing the Power key, press and hold the Volume down key.
- Continue to hold the Volume down key until the device finishes restarting.
- Safe mode will display in the bottom left corner of the screen.
- Release the Volume down key when you see Safe Mode.
- Uninstall apps that are causing a problem.
You may consider the problem fixed if the phone boots up, but if not, then move on to the next procedure.
Attempt to boot the phone Recovery mode
Here’s the thing, even if your phone has a serious firmware issue for as long as the hardware is fine, it should boot up in Recovery mode successfully and if it does, then problem fixed! The next thing you should do is try to reboot the phone normally to see if it powers up and boots up. If there’s still an issue while trying to boot it up, then boot it back into the recovery mode and wipe cache partition. After this and some issues are still occurring, then perform the Master reset.
How to boot Galaxy S7 Edge in recovery mode and wipe cache partition
- Turn off the device.
- Press and hold the Volume Up key, Home key, and Power key at the same time.
- When the phone powers on, the Android System Recovery screen appears approx. 30 seconds later.
- Release all of the keys.
- Press the Volume down key to highlight “wipe cache partition.”
- Press the Power key to select.
- Press the Volume down key to highlight “yes” and 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.

- Turn off the device.
- Press and hold the Volume Up key and the Home key, then press and hold the Power key.
- 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).
- Press the Volume down key several times to highlight “wipe data / factory reset”.
- Press Power button to select.
- Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
- Press Power button to select and start the master reset.
