Troubleshooting Galaxy S7 with disabled Wi-Fi switch after Nougat update

Problem: Hi! I have a samsung galaxy S7, i get a notification that I need to update my phone to a new version 7.0 and so I did. It’s been doing well so far after it finished the process, sadly after I tried to open my Wifi menu to connect to the internet it won’t allow me to continue. It freezes and it stays there for 15 minutes after I realize it’s getting nowhere I restarted my phone and open the wifi again but just like before it’s stuck. Is there a possible fix to this or should I go back to the older version? Thanks a lot

Solution: Hello! This kind of issue is common to Samsung Galaxy S7 and other android devices as well. And mostly, it happens after a software update or it could be triggered by other factors such as corrupted files and third party apps. We are confident that this issue will be resolve as long as it is a software related problem because if it’s a hardware related then troubleshooting procedures are useless. Below are the easy steps on how to perform troubleshooting:

Step 1: Run Your Galaxy S7 in Safe mode

In most cases, an issue like this is triggered by third party apps especially the out of date one. Before updating your system, make sure that all your apps are updated to the latest version to minimize the incompatibility issues. There are cases that some apps are not compatible to the next system update that is why it is important to have the latest update to make sure.

Now, to determine the culprit, follow the steps below on how to run in safe mode:

  1. Press and hold the Power key.
  2. When Samsung Galaxy S7 logo appears, release the Power key and immediately hold the volume down key.
  3. Continue holding the Volume Down key until it finishes its rebooting.
  4. When “Safe mode” appears on the screen immediately release the Volume Down key.

While in this mode, try going to the Wifi menu if you are able or turn on the wifi. If so, then you can remove the suspected app. In case you are not sure which app to remove, just try to remember which app you installed before having this issue or you can remove all the apps and reinstall only the important.

Step 2: Clear System cache partition

If booting to safe mode did not resolve the issue or still freezes when opening the Wifi menu, then we recommend to proceed on clearing the system cache partition. This procedure is easy and very safe for your device. We will be deleting the old temporary files that was supposed to be cleared during the update process and let your device create a new one. The reason that your device freezes, it may still contain the old temporary files and gives confusion to the system. Follow the steps below on how to clear the system 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 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.

Step 3: Perform Hard Reset

This would be the last procedure that you should do if all fails and the issue still occurs. We recommend this only if no other procedures available to perform or you’ve already done making backups to all important files. The hard reset will clear all files and apps in your device and restore it back to default factory settings. We recommend to make backups to all important files and save it in a separate storage device, in your computer or to you SD card. Follow the steps below to perform the procedures:

  1. Turn off your Samsung Galaxy S7.
  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 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.

Step 4: Visit a tech

In case it didn’t resolve  the issue and still freezes when opening the Wifi menu, then bring it to the nearest service center to let the tech handle the issue because it could be serious. But, we are confident that this issue will be resolve by a  reset.
