How to troubleshoot your Galaxy S7 Edge that keeps on restarting

Problem: Hi. it’s been a week that my phone is acting weird, I really don’t have time figure out what causes it because I got some errand to run. I have to leave my phone when I go to work because it keeps on restarting and it really annoys me. I can’t imagine how many times I restarted my device but it’s not working. Hopefully you can give some suggestions to fix it or I need to replace it with a new one?

Solution: Hello! There are a lot of factors to consider why your phone restarts itself without apparent reason. This issue often occurs if the system has been updated or perhaps, one of your downloaded applications is the culprit that’s preventing the device to work normally. Also, you need to make sure that the battery is not defective because once the battery could not supply the required power, it’s possible that the device restarts on it’s own. Let’s try to see if we can do something for it by performing the troubleshooting procedures below…

Step 1: Try to Connect  your phone to the charger and let it charge for 10 to 20 minutes

Since we are not sure what really caused the device to restart, we need to figure it out if the battery is defective or not. You can connect the device to it’s charger and observe if the LED indicator shows it’s charging and then leave it for 10 to 20 minutes. If the indicator shows it’s charging fine, then obviously the battery is good and you can proceed to the next procedure for further troubleshooting. But once it is connected to the charger and your phone is not responding or the charging icon is not showing on the screen, it is evident that the battery is defective, you can bring it to the nearest shop in your area to be replaced by a new battery by the tech.

Step 2: There might be third-party applications that caused the issue

Assuming that the battery is fine, you can boot your phone in Safe mode to determine if there were third-party applications that triggered the issue to occur. Take note that while in this state all downloaded applications will be temporarily disabled. So, if the device is not restarting while in this mode, then one of your apps triggered it. Try to find the culprit and uninstall it to fix the issue. This is how you boot your device in safe mode…

  1. Press and hold the Power key.
  2. If Samsung Galaxy logo appears, release the Power key and simply hold the Volume Down key.
  3. Continue holding the Volume Down key until the device finishes rebooting.
  4. If you can see “Safe Mode” in the bottom left corner of the screen then, you may release the Volume Down key.

However, if the issue is still happening while in this mode, jump to the next procedure.

Step 3: Delete the System Cache in your phone

After booting in Safe mode and the issue is still happening, you can try deleting the system caches of the device. If system caches got corrupted or outdated, that could be one of the reasons why the problem occurs. You can delete those old caches so that the device will create newer caches to replace those corrupt and obsolete ones. Here’s how…

  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 deleting the system caches won’t fix the problem you can proceed to the next procedure.

Step 4: Perform Master reset on your Galaxy S7 Edge

If all those procedures provided won’t worked on your phone it’s time for you to do the master reset. This time you will bring back your phone to its default settings wherein all your files, settings and preferences will be deleted. So, before resetting the device try to backup everything or transfer all of your data to your computer or SD card:

  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.
  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 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.

Galaxy S7 Edge gets stuck on the logo and won’t continue to start

Problem: Hi guys. I am hoping you can help me with my phone because recently it started to have serious issues. First, the phone seemed to have slowed down that it would take a long time to open apps, then there were freezes, lags and all that and then it just started getting stuck on the logo and won’t move on to the home screen. I don’t have a clue what the issue is let alone how to fix it. So if you guys can help me out, I would surely appreciate it. Thanks a lot.

Troubleshooting: It seems like your phone gradually suffered performance issues prior to getting stuck during boot up. We cannot quite extract more information from your description however, it’s possible that it’s caused by a minor app problem or a more serious firmware issue. You have to do some troubleshooting procedures to be able to know what the problem really is. Here’s what you have to do…

  1. Do the forced reboot procedure. Press and hold the Volume down and Power keys together for 10 seconds to reboot the device. While it may reboot normally, what you just did is the forced reboot procedure which is effective in dealing with minor firmware issues. It’s imperative that you do this procedure first of all.
  2. Try to boot your phone in safe mode. As I said, it’s possible that the problem is caused by an app and we don’t know for sure if it’s a third-party or pre-installed. So, try to run your device in this mode as it disables all third-parties and leave pre-installed ones running. If successful, then you just have to find the apps that cause the problem and uninstall them.
  3. Delete the system cache. System caches can easily get corrupted especially during firmware updates. So, to rule out the possibility that the problem is caused by some corrupt caches, boot your phone up in recovery mode and if successful, wipe the cache partition.
  4. Master reset your phone. I understand you may lose your important files and data that are saved in your phone’s internal storage but you really don’t have a choice. After all, if you brought your device to a technician, the first thing he would do is reset it so it’s better that you do this by yourself before seeking assistance from someone. You do this if the phone can successfully boot up in recovery mode and that wiping the cache partition didn’t work.
  5. Bring your phone to a tech or shop. As far as troubleshooting is concerned, you’ve done what you should do to try to bring your phone back to life to no avail. Therefore, it’s time you brought it to a tech and have it checked.

Galaxy S7 Edge powers up but won’t continue booting up after reaching the logo

Problem: I’ve been using my chrome browser when my phone shuts off by itself and turn back on. But, when it reach to Samsung logo it stops there and restarts again it keeps repeating until the devices run out of battery. I decided to charge it until it’s full, but when I turned it on it keeps repeating the same cycle again and it’s really annoying. Now, I tried to google for a fix all over the internet and I can’t find any useful suggestions. I’ve some of your post and hopefully I can get some help from you guys. Please help me fix my phone badly need it and I have lots of stuff save in there. Thnx much!

Solution: Did you update your firmware before the issue occurred? If so, then that could be one of the possibilities why the device reboots on its own. But since you did not mentioned you did an update, then I will assume that you still downloaded the new firmware. In this case, what we would like you to do is to isolate the issue first by booting the device in Safe mode. In this diagnostic state, all third-party apps i will be temporarily disabled. If the issue is not happening anymore, probably, one of your downloaded applications is the culprit. You can uninstall suspected apps and observe if the problem will still occur.

However, if there’s no progress after booting it in Safe mode it is possible that the system caches of your phone are outdated or corrupt. So, wiping the cache partition is necessary to delete all of them so that they will be replaced by new caches that is compatible to the system. After the procedure observe closely if the problem is still happening. If so, you can perform the next procedure by resetting your device.

Since you already did all necessary procedures but  the issue still happening, then most likely it is an issue with the firmware. You can perform the master reset procedure to bring back your phone to its default settings and to fix the issue as well. But take note that in resetting the device all your files stored will be deleted. So, before you proceed to the steps we provided make sure to backup all of them.
