Samsung Galaxy S7 Edge got stuck on boot screen after updating to Nougat [Troubleshooting Guide]

Getting stuck on boot screen is one of the common issues with smartphones that are experiencing firmware related issues. High-end devices like the Samsung Galaxy S7 Edge are not exempted from this kind of problem as its specs have nothing to do with it. There are, however, cases wherein a hardware issue may lead to the corruption of some of the files that may also result to this kind of problem. We need to troubleshoot to know exactly what the problem is and what needs to be done to fix it.

In this post, I will walk you through in troubleshooting your Galaxy S7 Edge that got stuck on the boot screen shortly after the Nougat update. It might just be a coincidence that this problem occurs after the phone got updated but we also have to look into it. The good news is, this problem may not be as complex as it may seem so there’s a big chance we can fix it especially that it occurred just after an update. So, read 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. Odds are that there are already existing solutions on our website or at least, there are similar problems we already fixed. So, try to find ones that are similar or related to your problem.

How to troubleshoot Galaxy S7 Edge that got stuck on boot screen

The purpose of our troubleshooting guide is to help owners determine what the real problem is all about, why it keeps on happening and what needs to be done to fix it. While we don’t suggest procedures that can potentially damage your device, things might still happen while you’re troubleshooting so proceed at your own risk. Now, before we jump to our troubleshooting, here’s one of the messages we received from our readers:

Problem: Hi! I own the Samsung Galaxy S7 Edge for many months now. Ever since I got it last year, I’ve encountered a lot of issues with it but I was able to fix them as majority have something to do with the apps and other functions. The most recent issue, however, seems too difficult to fix because the phone won’t boot up successfully so I cannot do some troubleshooting. When I turn the phone on, it stops on the logo or on the black screen and it may stay on it until I turn the phone off but the same thing happens when I turn it back on. This is the reason why I’m contacting you guys, I don’t know what to do about it. The problem started after I updated the phone. I hope you can help me. Thanks.

Troubleshooting: There’s a possibility that the problem is caused by one or some of the apps and it’s also possible it’s a firmware issue considering the fact that it occurred shortly after the Nougat update. With that said, here’s what I suggest you do about it:

Step 1: Perform the soft reset procedure on your Galaxy S7 Edge

A reboot is something we often do when the phone starts to act a little crazy. It’s effective in some problems but when it comes to some firmware-related glitches and issues, it’s not. There’s another thing we call “soft reset” which is just like a reboot only that it refreshes the phone’s memory better. It’s equivalent to the “battery pull” procedure we often did with phones that have removable batteries. Since your Galaxy S7 Edge has a non-removable battery, you just need press and hold buttons to simulate it and here’s how…

  • Press and hold the Volume Down and Power keys together for 10 seconds.

Assuming your phone still has enough battery to power up its components and that the problem is indeed caused by a firmware glitch, then device should reboot normally. There’s no guarantee that this procedure can fix the problem but at this point, it’s the most logical thing to do. If the phone, however, is still stuck on the boot screen, then move on.

Step 2: Charge the phone to reach 50% battery

We just need to make sure that there’s enough battery to power up all hardware components as well as load the firmware and services. So, plug the phone in and leave it charging for 30 minutes. Aside from replenishing the battery, we’re also trying to find out if the phone can still successfully charge its battery. The usual charging symbol should appear on the screen and the LED indicator should be lit up above the display. If none of these signs show, then your phone isn’t charging. Try to read our posts that may help you make the phone charge:

Step 3: Attempt to boot your phone in Safe mode

Assuming your phone charges fine but still won’t turn on after leaving it plugged in for 30 minutes, then you should try to load the firmware and core services without interference from third-party apps. Which means,  you need to try to boot your phone in safe mode. Doing so will temporarily disable all third-party apps that might be causing the problem, here’s how  you do it on your S7 Edge:

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

Assuming the phone has successfully booted up in this mode, it confirms our suspicion that the problem is caused by one or some of the third-party apps. You have to find the culprits and uninstall them one by one until the phone can successfully boot up in normal mode. This is how you’re going to uninstall apps from your Galaxy S7 Edge:

  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.

You may have to try to reboot it in normal mode every time you uninstall an app to confirm if the problem is fixed.

Step 4: Attempt to boot your phone in Recovery mode

If booting in Safe mode was unsuccessful, then there’s another mode you have to try to boot your phone into–Android system recovery or Recovery mode. Doing so will power up all the hardware components of your phone but the Android interface and apps won’t be loaded. If the phone is suffering even from a serious firmware problem, it should still be able to boot in this mode. What makes it very important is that fact that you could do a couple of very effective troubleshooting procedures while in this mode like wiping the cache partition and doing the master reset. That said, here’s how you boot your S7 Edge in recovery mode and wipe the 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.

You don’t have to worry about doing this because none of your files and data will be deleted and it has a reset-like effect. If successful, your phone should be able to boot up successfully but it may take a little longer to do so since the phone will take time rebuilding the caches.

If, however, your phone cannot boot up successfully after wiping the cache partition, then you should already reset your phone. This will delete all your files and data saved in the phone’s internal storage and there’s no way you can make a backup without booting in normal mode or safe mode. So, it’s a compromise…

  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 the problem is still not resolved after this, then bring the phone to the shop and have the tech fix it for you. The firmware may need to be reinstalled.
