How to troubleshoot your Galaxy S7 Edge that started freezing and rebooting

Problem: Hi, recently my Samsung S7 Edge has become somewhat unreliable. It seemed to start with a faint lag after the software was updated most recently. However, in the last couple of weeks, this lag has led to a number of issues that seem related. It seems particularly related to Wi-fi settings, when I try to connect to Wi-Fi, not consistently but seems to happen only when I try connecting, the device reboots, showing only the Samsung logo. The device then seems to go in a loop and reboot about every 30 to 60 seconds, along with the device overheating dramatically. Another minor issue that seems to be connected to this is the absence of the keyboard once it has rebooted, it fails to show at any point. Any help is greatly appreciated, thank you in advance!

Solution: As you stated that these issues happen after the update, it’s not far that the software data was ruined on the process and caused the device to freeze and reboots without apparent reason. But since we are not sure what triggered the problem,so, this time we will figure it out what makes your phone to function abnormally through performing the basic troubleshooting procedures. Here are the methods that you need to do:

Step 1: Boot in Safe mode for there might be an app caused it

In booting in safe mode, we have to figure it out if one of your downloaded applications is the culprit and caused the issue to occur. While in this state, all third-party apps will be eliminated from the system for a while to see if your device will still freeze and reboots. Because if it will, there’s an app you need to uninstall. To do so, you can start uninstalling every app you have starting from the recent one you had downloaded. This is 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.

After you restarted in safe mode and your phone still reboots and lags, then there might be a software issue and you can proceed to the next method.

Step 2: Delete the system caches so they’ll be replaced

Usually, if the system had been updated there is a chance that the caches in the directory will get corrupted, and if that happens, that would be the reason that several performance-related issues occurs. So, in this method, we will erase all old temporary files in the partition so that newer and fresher caches will be created. But don’t you worry about it all your saved files will be intact after the procedure. Follow these steps:

  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 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 your phone doesn’t have a problem after deleting the cache partition, then it is the corrupted caches triggered the problem. However, if the issue persists you phone might have a serious firmware issue and you can proceed to the next method.

Step 3: Reset your phone

Since you already performed all  procedures but the issue still happening, so, this time you don’t have a choice but to do the reset on your phone to make sure that all bugs that might caused the issue will be eliminated. However, before you do the reset make sure to backup everything because all saved files and downloaded apps will be deleted from the system. You can transfer all of it to your SD card or personal computer before you begin 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. 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 after the reset will fix the issue but if not, then it’s time to have somebody to check it out as the firmware may need to be reinstalled.
