Troubleshoot Most Common Samsung Galaxy J6+ Problems and Fixes

1. WiFi doesn’t connect to a specific network on Samsung Galaxy J6+

We’ve seen many Android users encountered this problem. And if you’re facing this problem on your Galaxy J6+, then you’re not the only one. This problem usually happens while the user try to connect this phone to a particular network but phone denies that.

It can throw different errors like ‘unable to connect’, ‘connection failed’, ‘network authentication failed’ and it goes on. If you’re sure that the problem is somewhere hooked within your phone, you just need to try the following recommendations. We are pretty sure that one of these should help you fix this WiFi connectivity problem on your Galaxy J6+.

  1. First of all, you must ensure that the WiFi network you’re trying to connect is working fine. Many times, users are failed to observe that problem is linked to that WiFi source. Therefore, you should thoroughly check that router.
  2. To be sure that only you’re the one facing this problem, just try to connect any other phone to that network. If that connects successfully, the upcoming solutions you need to apply on your phone.
  3. Restart your phone. Though this action doesn’t look that big, still just restarting helps to fix many problems on Android phones. Just restart your phone and try connecting your phone again to that WiFi network.
  4. Make sure that you have the correct (updated) password or login details of that WiFi Network. Sometimes it happens that WiFi Network password or login details are changed and the user remains unaware of that. Confirm if there’s any change made to this network.
  5. Next, open the WiFi Settings> Tap on the Network that you’re connected -> Tap on ‘Forget’. Now, reconnect to that WiFi network. This should help you connect that network successfully.
  6. Further, if none of the above doesn’t work, just tap on Settings-> Backup and reset-> Reset Network Settings-> Perform this action. This will reset the entire Network settings on this phone.

Thereafter, you should be able to connect your phone to the WiFi Network successfully. Apart from that, there are possibilities that the problem or bug is somewhat linked to the WiFi router. So, ensure to check the WiFi Network thoroughly.

2. Bluetooth headsets (or any other device) won’t pair on Galaxy J6+ troubleshooting steps

While connecting to our personal headsets or similar device, you might find yourself stuck. Such issues are more likely happen to those who frequently use or switch different Bluetooth devices. Personally, I face this problem many times connect my Dodocool headphones to my OnePlus 5 smartphone.

Still, I couldn’t find a specific reason behind that. To troubleshoot that, I usually restart both the devices and it works. Therefore, our first recommendation would be the same. The following solutions should help you tackle this problem on your Samsung Galaxy J6+ smartphone.

  1. Reboot both the device. If you’re connecting your headphones to your phone and it couldn’t happen so, just reboot both the devices and then try to connect them again. It works most of the time.
  2. If the above solution doesn’t work, open the Bluetooth Settings -> Tap on the headphones and then tap on Forget. Then, reform the connection and this time, it should work.
  3. For Android Oreo and above users, there’s a certain feature that appears over the Notification panel that allows users to switch between headphones and phone’s speakers. So, even if your phone is connected and you still couldn’t listen to the music, there are greater chances that phone’s speaker has been selected for the output. Check the notification panel.
  4. At last, we recommend you to reset the Network Settings. This will remove all the pre-formed connection and clutter causing connectivity problems. Just open Backup and reset -> Tap on Network Settings -> and tap on reset.

These solutions are sufficient enough to tackle such connectivity problems linked to Bluetooth devices. Also, it is recommended that you thoroughly check the Bluetooth headset. That might defective as well.

You’ve just opened the box and figure that the display screen of the phone goes black and nothing happens further. There are lot of chances that this problem is no ordinary one. Possibly there could be two reasons; either the one or more hardware parts have been malfunctioned or the Android OS itself has crashed for some reasons.

    5. If this mode boots up successfully, that means some applications are preventing your phone boot normally.
    6. Now, open the Settings -> Apps – Apps List and remove all the applications that you’ve installed recently
    7. Now, reboot your phone.
  2. In case your device doesn’t show up the Safe Mode, you should try to clear its cache memory. That will remove clutter and junk files that might be causing this problem. For that purpose, follow our tutorial: how to clear cache on Samsung Galaxy J6 smartphone.
  3. Lastly, you can try to format your phone completely. Remember, this will wipe your phone thoroughly, everything that is stored within the phone is deleted. Most importantly, this works most of the time. Just follow our tutorial: how to hard reset Samsung Galaxy J6 using the recovery mode.

This problem doesn’t limited on certain smartphones, it could happen to any Samsung phone. We find users stuck with multiple issues like boot stuck, boot loops, unstable interface, lags and similar ones.

During an update process, the old cache files or system files might get corrupted. Therefore one should get rid of that cache data. Just boot into the recovery mode and perform ‘wipe cache partition’ action.
  2. Further, you can factory reset your phone. After an update (official or manual), this is the most recommended step that users should take. This wipes all the old files and turns the device into a factory fresh piece. Again, use the recovery mode and perform ‘Wipe data/factory reset’ action.

Whether it’s a camera application or game, app crashes/freezes can happen to any application. There can be different reasons that a certain app/game is behaving abnormally. While we use our phone for a long time, it is normal to observe app crashes and freezes.

These issues occur most of the time because of the cached data. Each time we open application/game, it accumulates/fetches some temporary data/files. These files/data turn into trash over time and eventually affects the performance of an application/game. If you’re facing app crashes/freezes on your Samsung Galaxy J6+ smartphone, the following troubleshooting solutions should help:

  3. You can uninstall that application/game. Then, install the updated version directly from the Google Play store. This method works most of the time.
  4. If yet that doesn’t work, there are chances that some application (applications) are resisting this app work normally. To check that, just boot into the ‘Safe Mode’ and observe this application. If that works normally, that means a third-party app or service is causing that problem. Just try to uninstall third-party apps from your phone.

Therefore, before you troubleshoot the phone, you better check the same thing on other smartphones. You should check the signal health and strengths of the same network on other smartphones. If these things are same, that simply means that problem is Network not with your phone.
