Among the most common issues with the Samsung Galaxy S7 Edge users reported after an update are about the units that won’t turn on and boot up. Before we jump into our troubleshooting, I just want to point out the difference between not turning on and not booting up so that it would be clearer to our readers what’s really happening with their phones.

When you say that your phone won’t turn on, it means that it doesn’t respond when you press the Power key; the screen remains black and won’t even flicker and the LED indicators won’t light up. You can spend hours and hours press the power key but your device will stay dead.

On the other hand, if you say that your device doesn’t boot up, it means that it powers on but gets stuck during boot up or restarts on its own.

Now that I’ve differentiated these two issues, let’s go to our troubleshooting but before anything else, if you have other issues with your phone, make sure you visit our S7 Edge troubleshooting page where we list down all solutions and troubleshooting guides we published on our website.

If you need more assistance, you can also contact us by completing our Android issues questionnaire. Don’t worry, it’s free but we ask you to provide us with all the information about the problem so that we can help you better.

Troubleshooting Galaxy S7 Edge that won’t turn on

There are various reasons why your device refuses to come back on and that there’s no apparent cause or you haven’t done anything unusual. Below is one of the complaints we receive from our readers. Read on to learn more about this issue…

Problem: Hello. I am hoping you can get back to me and help me with my problem as soon as possible because I use my phone for my job and now it won’t turn on. I own a Galaxy S7 Edge. I bought this a few months ago and got my provider set it up so I can send and receive texts and calls and do some light browsing. For some reason, it turned off on its and when I tried to turn it on, it just won’t respond. I’m not really sure what the issue is…hell, I don’t know what the issue is. So, if you know how to fix this problem, please walk me through. Thank you.

Troubleshooting: There are possibilities that we need to look into so that we’ll know what really is the problem with your device. Let’s try to eliminate one possibility after another until we discover the issue. Please follow the troubleshooting steps below…

Step 1: Forced reboot your Galaxy S7 Edge

The first thing that we need to rule out is the possibility that you phone’s system just crashed leaving it unresponsive. There have been a lot of cases wherein the devices refuses to power up but when the owners did the forced reboot procedure, they powered up. Therefore, you need to try this procedure before diving into other troubleshooting steps:

  • Press and hold the Volume Down and Power keys together for 15 seconds. If there’s enough battery left and assuming it’s just a system crash, the phone should reboot.

Step 2: Attempt to boot the phone in safe mode

Sometimes third-party apps may cause problems like this and since we don’t know yet if it’s a firmware or app-related issue, let’s rule out the latter by booting the device 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.

There is no guarantee that you can boot your device in safe mode, so if this procedure failed, let’s try to make sure that your phone has enough battery.

Step 3: Plug the phone and leave it charging for 10 minutes

Perhaps the reason why your device isn’t turning on is because there isn’t enough battery to power up its components. It happens all the time; the user saw the device turned off but didn’t notice the battery icon has turned red. When the power key is hit, the phone wouldn’t respond because there’s not enough power to bring it back to life. So, plug the device in and leave it for 10 minutes.

But aside from the obvious reason, this procedure will also tell you if there’s an issue with the hardware or not. If the phone displays the usual charging icon and lights up its LED, then there’s no problem with its components.

Step 4: Try to do the forced reboot procedure again

But this time do it while the phone is plugged. If your device didn’t show the charging indicators when you plugged it in, there’s still a chance it’s just a system crash combined with drained battery. To rule this possibility out, press and hold the Volume Down button and power keys together for 15 seconds or until the phone reboots.

Step 5: Attempt to boot your device in recovery mode

The Android system recovery, otherwise known as Recovery Mode, requires all hardware components to be powered up but it doesn’t load the usual Android user interface. Meaning, the phone is running in its barebones. If your device has hardware issues, it may not be able to boot in this state, otherwise, you should see the black screen with blue texts.

Here’s how you boot your Galaxy S7 Edge in recovery mode:

  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.

Step 6: Send it in for checkup / repair

After doing all the steps above and your phone is still not responding or won’t boot up, it’s time you sent it in for checkup and/or repair. There’s not much you can do about it at this point.

Troubleshooting Galaxy S7 Edge that won’t boot up

In simplest terms, booting up is the process of loading the firmware, apps and services and this is the basic process the phone will have to undergo to be ready for usage. Some Galaxy S7 Edge owners however, complained their devices just won’t continue to boot up to the Home screen. Many suggested that it could be the update that caused it since the problem started shortly after the firmware was bumped to a higher version. So, we’ll look into it…

Step 1: Try booting your phone in safe mode

Apparently, your device is powering up, it just cannot continue loading its firmware and apps. Sometimes, third-party apps crash due to the new firmware that was installed. This reaction may affect the new firmware as a whole and this problem occurs. Therefore, it’s logical to boot the phone first in safe mode as all third-party apps are disabled when you do so.

Step 2: Boot your device in recovery mode and delete system cache

This procedure may work if the phone’s firmware isn’t modified. If the problem started after the regular update, then there’s a chance the problem is caused by some corrupt caches. In this case, you need to delete caches created by previous firmware by booting in recovery mode and choose ‘wipe cache partition’ option.

Turn off your Samsung Galaxy S7 Edge.

  1. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  2. When the Samsung Galaxy S7 Edge 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.

This might be the only thing you’ll have to do to make your device boot normally again but if it fails, the next step will take care of the problem.

Step 3: Perform the master reset

This is your last resort and sad to say that you may lose every bit of data and files saved in your phone. There’s nothing you can do about them because the device won’t even boot in safe mode so there’s no time to make a backup.

  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 guides can help you.
