Troubleshooting Galaxy J7 with disabled Wi-Fi switch

As I said earlier, this problem has also been happening with the S3 before and based on the reports of our readers, the problem is actually easy to fix. It may fall as a minor glitch either on the system or the hardware and there’s always something you can do about it but before we jump to our solution or troubleshooting guide, here’s one problem that best describes this issue…

Problem: Hi guys. My name is Mark and I own a new Galaxy J7 I bought a couple of months ago. It’s not as fancy as the S7 Edge but definitely does a good when it comes to my needs such as emails, facebook, twitter, browsing, texting and calling. The thing is that recently, I noticed that I could no longer connect to my home Wi-Fi. I have subscribed for mobile data but when I’m at home, I have to be able to connect to my Wi-fi since the data signal in my area isn’t that good. But I noticed that the switch is kind of disabled like I cannot turn it on or off, it’s greyed out. As a result, I am forced to use mobile data when I’m at home since Wi-Fi isn’t working. Is there something I can do about this? Thanks a lot!

Now let’s go back to our troubleshooting…

Step 1: Boot your Galaxy J7 in Safe mode to know if the switch is still disabled

This will tell us immediately if the problem is caused by by one or some of your third-party apps. So, try to follow the steps below to reboot your phone in safe mode:

  1. Power off your Galaxy J7. Press and hold the Power key, tap Power off and then touch POWER OFF to confirm.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

If the Wi-fi switch gets enabled in safe mode, toggle it on and off and then try to connect to your home Wi-Fi. After a successful connection, test your phone to see if it can browse the web and if so, leave the switch turned on and then reboot your phone in normal mode and then try again. If the switch is still disabled, then there’s an app that’s causing the problem find that app and then uninstall it. You may need to uninstall more than one app to fix the problem. However, if the problem still persists after uninstalling suspected apps, move on to the next step.

Step 2: Delete the system caches as some of them may have already been corrupted

The system create caches for every service and operation in your device including radio reception. There’s a chance the cache for the Wi-fi got corrupted for some reason. Since you don’t have access to individual caches, you need to delete all system cache so that the firmware will create new ones that are completely compatible with it. Reboot your phone in recovery mode and then wipe cache partition. Here’s how…

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

After this and the switch is still disabled, the next step will fix it.

Step 3: Perform the Master Reset on your Galaxy J7

Unless the firmware got corrupted or some of the system files got deleted, this problem is actually a simple one and can be fixed by a reset. But the reason this procedure always comes at the end is because of the hassle the user will have to go through in backing up important files and data before the reset and restoring them after. Now, here’s how you reset your Galaxy J7:

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off your Galaxy J7.
  3. Press and hold the Volume Up button and the Home key, then press and hold the Power key.
  4. When the device logo screen displays, release only the Power key
  5. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  6. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  7. Press Power button to select.
  8. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  9. Press Power button to select and start the master reset.
  10. When the master reset is complete, ‘Reboot system now’ is highlighted.
  11. Press the Power key to restart the device.

I hope this helps. Thanks for reading.

Samsung Galaxy S7 Wi-Fi switch disabled after Android Nougat update [Troubleshooting Guide]

I cannot stress enough how important Wi-Fi is with your #Samsung Galaxy S7 (#GalaxyS7). Needless to say, if it doesn’t work, then you have to perform troubleshooting procedures to determine whether the problem can be fixed on your end or you will need a technician that may help you solve the issue.

In this post, I will tackle 3 issues that have something to do with Wi-Fi. The first one is about the Wi-Fi switch that’s reportedly been disabled shortly after an update. More often this problem is caused by some corrupt caches or perhaps some apps crashed and caused the system to crash as well. Read on to know how to troubleshoot this problem as well as the other issues tackled in this post.

But before we jump right into our troubleshooting, if you have other issues with your phone, make sure to drop by our troubleshooting page for we have already addressed hundreds of problems with this device since it was released.

Galaxy S7 Wi-Fi switch greyed out after the Nougat update

Problem: Hi guys. My phone is acting up after the most recent update. It’s a Galaxy S7 phone and I recently downloaded the Nougat update. It took almost an hour before the phone rebooted on its own as a sign that the update was successfully installed. That’s what I think it is but I’m not really sure about it. But anyway, after the update, my phone could no longer connect to the internet via Wi-Fi and when I investigated, I found out that the Wi-Fi switch is disabled or greyed out. Basically, the device can’t connect using such method, although I can browse the web and download apps using data. The thing is, I have to pay for the data and I already have Wi-Fi at home so I need my phone to work like before. Can you help me figure this out?

Troubleshooting: During firmware updates, there are services that may not function properly after the new firmware is installed. This is due to some caches or data that got corrupted. In this section, I will tackle about the greyed out Wi-Fi switch which seemed to have bugged many Galaxy S7 owners after Nougat.

We’ve already addressed a lot of issues like this in the past and there were cases wherein the problem persisted after basic troubleshooting but there were also ones that were easily fixed after doing a procedure or two. With that being said, this is what you should do…

Step 1: Reboot in safe mode and toggle Wi-Fi switch on/off

Doing this will immediately isolate the problem so you will know if one or some of your downloaded apps is causing the issue. This method is very effective with S3 and S5 that also encountered issues like this before so I want you to try it out and see if the problem gets fixed. This is how you start your phone up in safe mode…

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 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.

If the switch is still disabled in this mode, then you have to perform a couple of firmware-related troubleshooting procedures.

Step 2: Delete the system cache

Some caches may have been corrupted and one of them may have been the cache for Wi-Fi. The thing with caches is that you can delete them and still expect nothing will happen with your device, however, when they get corrupted and the new system uses those corrupt files, issues like this may occur. So, we need to delete them so the system will replace them with new ones and this is how you do it:

  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.

After this, try to check the Wi-Fi switch if it’s still disabled and if so, then you have no other choice but to do the next step.

Step 3: Perform the Master Reset

You are left with no choice but to reset your device if the previous steps didn’t work out. Doing this will surely fix the problem but it always comes last because of the hassle you have to undergo in backing up your data and files and restoring them after.

  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.

I hope this helps.

Galaxy S7 could not connect to Wifi After System Update

Problem: I updated the system of my phone with no luck, I don’t understand what happened. Yesterday, when I tried to connect to my Wifi I noticed that my phone wouldn’t connect even the switch is turned on. I rebooted it also for several times but still could not connect. Any help would be greatly appreciated.

Solution: The Samsung Galaxy S7 can be considered as one of the most advanced phones available in the market today but like other devices it’s not perfect and still prone to bugs and other issues. As you stated that the problem occurs after system update, then most probably it is a firmware related issue or a downloaded app triggered it. On the other hand, hardware problem might also be the caused that your device is unable to connect on your Wifi. To determine what the problem is, all you need to do is perform software troubleshooting procedures that we provided below.

Restart your device in Safe mode. If you installed third-party apps to speed up or boost Wifi connection, that may be the reason that the issue is happening. You can boot your device in Safe mode to prevent all downloaded applications from running in the system and observe closely if the issue occurs. While in this state and your device can connect to your Wifi, then you can uninstall suspected apps until the issue is fix. Follow the procedure above on how to boot in safe mode.

Wipe the System Cache partition via recovery mode. If running in Safe mode won’t resolve the problem, then wiping the system cache partition might fix it. Through this method the temporary files where the caches were stored will be deleted to force the device to create newer caches that can make your phone run smoothly and fix this problem.

Perform a hard reset on your phone. If all the steps didn’t work, your last chance to fix the problem is to do master reset on your phone. Unlike the previous procedures, this method will delete everything like contacts, messages, music, videos and etc. So, before you proceed, make sure to transfer all your files to your computer and SD card because all of it will be deleted once you will bring back the device to its default settings.

Galaxy S7 Wi-Fi not working after system update

Problem: Hello! I’m not sure what is happening on my Samsung Galaxy S7 since I updated the system just this week ( I can’t remember the exact day) wherein the Wifi will turn on and off. I rebooted my phone and configured my Wifi settings but nothing works. Please help!

Solution: The first thing that you should do is to verify if your other devices could connect to your Wifi. If not, then it might be your internet connection has an issue and not your device. If this is the case, you can contact your Internet service provider for help to fix the problem. However, if only your Galaxy S7 could not connect to your Wifi, then most likely the device has a firmware or hardware related issue.

To determine what caused the problem you need to spend time performing the troubleshooting procedures by booting your phone in Safe mode. The purpose of this method is to identify if one of your third-party applications installed is the culprit. While in this state observe closely if the issue is still happening. If not, uninstall every suspected third-party app on your phone until the issue is fix.

However, while in Safe mode and the issue still occurs then probably the system caches had been corrupted. Try to delete the system caches and observe if there’s progress after performing the method. If the problem is still the same, you can proceed to your last resort by resetting the device. By bringing back the device to its factory default there is a big chance that the issue will be fixed. All leftover corrupted caches on your phone will be deleted and take note that all stored files will be deleted so much better to backup everything before you go through to the procedure.

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.

Galaxy S6 has greyed out Wi-Fi switch

Problem: I updated my Samsung S7 a few days ago to version 7.0 nougat. The phone is fine and other apps except for the wifi icon, it is greyed out and I can’t connect to a network. I already go to all the settings and still not working. Please help.

Solution: This is pretty much similar to the first issue and can be fixed by following the steps provided. And again, the possible cause of the issue might be because some old temporary files are corrupted or can be a third party apps. Now, to determine the culprit you can start by restarting your device and see if the greyed out icon is now usable. Then proceed and follow the remaining steps to make sure that you didn’t miss any steps.
