Solution: Well, it seems like this is only a minor firmware issue, in which, the caches that the device are using might have been ruined or outdated. As you stated that it restarts without apparent reason, then this is an indicator that there’s something wrong with the firmware triggered your phone to crash. But since we are not certain what the issue is, all you need to do is to figure it out through performing the basic troubleshooting procedures on your phone. But nothing to worry about these methods because these are all safe and won’t harm your phone. Here are the things that you should do:

Step 1: Restart your phone in Safe mode

Sometimes, due to incompatible apps that conflict the system inconsistencies on phone’s performance will occur without apparent reason. In this instance, we have to boot your device in safe mode to check if one of the downloaded applications is the culprit and prevent it from booting up successfully. So, while in this state all third-party apps will be disabled temporarily and the pre-installed will be running in the system. So, if the problem won’t persists, then there’s an app that you should uninstall from the system. This is how you 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.

But if the problems still happening there might be a serious issue that you to need to figure it out. You can proceed to the next method.

Step 2: Try to delete the Cache Partition for it may be corrupted

Before you can do the reset we recommend that you should perform first the wiping the cache partition on your phone. In this procedure, all temporary files stored in the partition will be erased so that newer caches will be replaced to the directory of your device. As a matter of fact, deleting the system caches from time to time is highly recommended to all android devices to make sure that the firmware would run smoothly and all files are updated always. Here are the steps to delete the cache partition:

  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.

After you do the wiping the cache partition and it does not resolve the problem, proceed to the last method.

Step 3: Do the Master Reset on your phone

If all the methods you performed does not resolve the issue, then your last resort is to do the reset. Meaning, we have to bring back your phone to its factory default and will erase everything you installed on your phone like: contacts, videos, music, settings and downloaded applications. Before you do so, try to create a backup to all your files by moving it to your SD card or computer prior following the steps.

  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.

I hope after resetting your phone the issue will be resolved, because if not, then all you need to do is bring your phone to the store where you bought it to be checked by the technician.
