Note 4 Cannot Connect To Any Wi-Fi

Problem: for a week now my phone cannot connect to any Wifi including my home. I tried taking out some of the apps and uploading pics and videos. My phone wont even do a software update because I dont have wifi. My Phone still have Insurance, in perfect condition as well.

Solution: Try checking first if the Wi-Fi of your phone can turn on. You will know that it is on if the slider switch of the Wi-Fi has turned green. If it is already green and you can’t connect to any Wi-Fi network then I suggest you proceed with wiping the cache partition of your phone from the recovery mode. This will delete the temporary data stored in your device which could be causing the problem. Once this is done restart your phone then check if the issue still occurs.

You should also check if a certain app you downloaded to your phone is causing this problem. To check if this is the case just start your phone in Safe Mode. In this mode only the pre-installed apps of your phone are allowed to run. Try to connect to any Wi-Fi network in this mode. If it can connect then the issue could be caused by an app. Find out what app this is and uninstall it.

One last troubleshooting that you can do is a factory reset. Make sure that you have backed up your phone data before doing this. Once the reset is done do not install anything in your phone yet. Check first if it is able to connect to a Wi-Fi network.

If after performing the steps listed above you still experience the same issue then I suggest you have your phone checked at a service center.

Note 4 Loses Ability To Connect To Internet

Problem: After BRIEF (but seemingly random) periods of time, my Galaxy Note 4 loses the ability to connect to some Internet places, with an error message saying it cannot connect to such-and-such a DNS location. Sometimes within a Facebook page even though FB was moving around fine just before then. I did the soft reset you mentioned. Helped about as long as a Power Restart,  e.g. minutes until it happens again. Sometimes hours. Doesn’t matter if Chrome or Firefox. I am at a loss. HELP!!!

Solution: Have you tried checking if the issue is caused by the particular connection that you are using? If you are using your home Wi-Fi network try using a different Wi-Fi network or try using your mobile data connection.

Once you have made sure that the network isn’t the problem then proceed with troubleshooting the phone. The first thing you should do is to wipe the cache partition of your device. This will erase the temporary data stored in your phone which if corrupt can cause this type of issue. Restart your phone then check if the issue still occurs.

Another factor that can cause this issue is a third party app installed in your phone. To check if this is the case simply start your phone in Safe Mode. In this mode only the pre-installed apps are allowed to run while apps you downloaded are disabled. If the issue does not occur in this mode then it is most likely caused by an app. Find out what app this is and uninstall it.

One last troubleshooting step that you should consider should the above steps fail is a factory reset. Take note that you should backup your phone data before doing this.

Note 4 Apps Not Working On LTE

Problem: The apps on my phone that connect to the Internet will not connect when my phone says I am on LTE, but when I am on 3G (restricting to CDMA 3G only) they work fine.  I can surf the Web on a browser on LTE,  but apps don’t work.  I have tried a soft reset, a hard reset and have spoken to my Carrier who “refreshed my device”.  None has any success. Please help! Oh I spoke to a guy in a Verdon store next to my work (he’s a friend) and he said he has no clue after trying a few things.

Solution: This is quite a strange problem. If the apps work on 3G then they should also work on LTE without any issues. Have you tried checking if a certain app installed in your phone is causing the problem? To do this just start your phone in Safe Mode. In this mode only the pre-installed apps are allowed to run. Check any of the pre-installed apps that are able to go online and see if they work on LTE. If they work then the problem could be caused by an app installed in your phone. Find out what app this is and uninstall it.

If the problem still occurs even in Safe Mode then you should try to contact your carrier and have them check your account. If your phone has a SIM then have them try another SIM in your device to check if the issue is account related.

Note 4 Wi-Fi Turns On After Software Update

Problem: Every since the software update whenever I am out of town my phone keeps turning on the Wi-Fi.  I have the connection optimizer turned off.  Went to Sprint and asked them about it and they told me there was glitch in the update that was being resolved,  that was over 3 weeks ago.  If you could tell what to do I would appreciate it.

Solution: If the connection optimizer is already turned off and this issue still occurs then try wiping the cache partition of your phone from the recovery mode. This will delete the temporary data of you phone that could be causing this problem.

If the problem still occurs then I recommend that you do a factory reset. Make sure to backup your phone data before doing the reset.

Note 4 LTE Not Working

Problem: my note 4 LTE is not working , i have selected LTE/WCDMA/GSM mode but in this mode i am not able to make and receive calls although sometimes it displays the 4g service above , but when i select GSM mode then the phone is working properly and i am getting the 2g speed.

Also i have done the hard reset then also the same problem is coming. Plz kindly help me to overcome this issue asap.

Solution: It’s possible that you could be in an area with a spotty LTE signal. I suggest you try moving to a different location where the LTE signal is strong  then check if the same issue occurs.

Note 4 Not Detecting Wi-Fi Network

Problem: My phone says my saved WiFi networks aren’t in range, even when I’m literally 3 feet from the router. It will connect to WiFi after I restart my phone.

Solution: If the phone needs to be restarted for it to be able to detect the Wi-Fi network then the issue could be caused by a glitch in the phone software. Wiping the cache partition of the phone from the recovery mode usually helps in this case. If the issue still occurs after this then I suggest you backup your phone data then do a factory reset.
