  • Read and understand why a powerful smartphone like your Samsung Galaxy S7 Edge may sometimes experience being stuck during boot up or enter a boot loop and learn how to troubleshoot it when it happens.

When it comes to powering on, it’s mostly the hardware and the battery that handle that but when it comes to booting up, it’s often the firmware, although we’ve already seen a lot of cases wherein the phone refuses to turn on due to firmware issues. But when the phone is stuck while booting up, we cannot blame the hardware because, apparently, the phone turns on it just couldn’t boot up.

In this article, I will tackle this issue with the Samsung Galaxy S7 Edge being the subject of our troubleshooting. When the phone is stuck in boot loop, it means that when it starts, it may only reach the logo or somewhere before or after that, then it powers down and starts back up again and reaches the same point. It could go on and on until the battery is all drained. Another case we have to tackle here is the issue wherein the phone is stuck during boot up; it won’t reboot but it also won’t bring your phone to the home screen. If you own this phone, have recently updated it and currently experiencing similar issue, read on to know what to do.

Samsung Galaxy S7 Edge got stuck in boot loop

Problem: Hi, last night my Samsung S7 Edge went off itself and was unresponsive. I plugged it in and after a few minutes it restarted. When it got to the home page it showed that the battery wasn’t low at all. Trying to access apps it said there were errors with whatsapp, messenger and samsung cloud. It was late so l decided to leave it until the morning. Over night it rebooted to the ‘Samsung Galaxy S7 Edge page’ with the screen lit up. I cannot get it off this. I have tried to restart it holding the power and vol down button. It goes off but turns back to this page seconds later. Holding the home button and vol up seem to do nothing. Should l let the battery drain and then see if it’s different when l try to charge it again? Is there anything else l can do or does it need to get sent away for repair. I can’t think of any damage that has been done to it. When it happened it was just on my bedside table. Thanks for your help, Fiona.

Solution: Based on your description, there are two possibilities  we should consider why the issue occurs out of the blue. It could be hardware or software-related problem. In fact, a lot of Samsung users were also have this type of issue especially if an update has been made in their device. But since you haven’t mentioned that you upgraded the firmware, then most likely some of the caches were outdated and failed the device to boot up completely. In this instance, the best thing that we want you to do is to isolate the problem by performing the basic troubleshooting procedures on your phone. Here are the procedures that you should do:

Step 1: Boot your phone in Safe mode

This method is an android environment in which, all your downloaded applications will be deactivated temporarily and only the built-in apps will run in the system of the phone. The purpose of booting it in safe mode is to determine if there were apps creates conflict in the system and triggered the problem to occur. But while in this state and it boots up completely, then there is a culprit on one of your apps and you should find that to fix the issue. Here’s how to boot 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.

While in this state and the device is still unresponsive and unable to boot up, then you can move on to the next step.

Step 2: Wipe the Cache Partition

Since the safe mode procedure didn’t help in fixing the problem, it’s time for you to move to the next method by deleting the system caches. Through this procedure, the files that the device had been using in the cache directory will be deleted so that your phone will create newer and fresher caches that are completely compatible with the new system. After doing so, try to see if your phone is able to boot up completely. If so, then the caches were outdated at that time and that’s the reason that the firmware crash and cannot boot up. You can follow these steps to delete the system cache:

  1. Turn off the phone.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  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.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

If, however, the issue is still happening, you can proceed to the next method for it may be a major firmware issue.

Step 3: Perform Master Reset

As far as troubleshooting is concern you all already performed all the necessary procedures to fix the issue. But since the problem still not fix, then you don’t have a choice but to perform the last method by bringing it back your phone to the default settings. But remember, in resetting the device all files and data will be erased. So, before doing it make sure to create a backup by transferring all of it to your computer or SD card.

Then, disable anti-theft by following the steps below. This will make sure you won’t get locked out of your device after the reset:

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Accounts.
  5. Tap Google.
  6. Tap your Google ID email address. If you have multiple accounts setup, you will need to repeat these steps for each account.
  7. Tap Menu.
  8. Tap Remove account.
  9. Tap REMOVE ACCOUNT.

After this, feel free to reset your phone through the 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.
  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.

If the problem is still not fixed after the reset, then obviously it is a hardware problem and you can bring it to the nearest accredited shop in your area to be checked by the technician.

Galaxy S7 Edge stuck during boot up, can’t go to home screen

Problem: For some reason, my Galaxy S7 Edge gets stuck on the logo or black screen when I try to turn it on. It won’t continue booting up to the home screen which is very alarming since it was working fine prior to the Nougat update. I haven’t really noticed any significant events that may have led to this problem except the update. So, if I’m right, the new operating system messed up my phone completely. It’s been like this for 4 days now and I badly need your help to make it work again. Thanks.

Troubleshooting: Based on your description, it’s pretty much a firmware issue since it started shortly after the update. And for this, the best thing that you should do or the most effective procedure you may be able to use is wiping the cache partition. It deletes and replaces all possibly corrupted system caches. You may also be right about the update messing up your phone but please note it might not be a serious issue.

However, if the wiping of the cache partition didn’t fix the problem, then you have to do the master reset before you seek assistance from a technician. Simply follow the same troubleshooting as the one above as these issues are basically the same and might have been caused by the same factor–update.

There are cases wherein this issue hinders the phone from getting inside Android system recovery menu (recovery mode), so you just have to press and hold both the Volume Down button and the Power keys together for 10 seconds until the phone reboots. The procedure is called Forced Reboot or soft reset, which is effective in dealing with minor firmware issues and crashes.
