Problem #1: Galaxy Note 5 hotspot and tethering stop working

I have a problem, with my mobile hotspot and tethering. I can activate it but my other devices cannot detect it. This is the 2nd time that I experienced  this. The first time, i did a master reset and everthing went back to normal, now i am experiencing the problem again. I have tried using it at safe mode, and still my other devices cannot detect my hotspot. all setting are correct, the device is not hidden. It is also set to allow all device to connect.  I even tried using the open setting, no passwords and still undetected. Hope you can help me on this. Regards. — Irvin

Solution: Hi Irvin. If the functions mentioned are not working, you can probe first if the reason behind is software in nature. Based on your description, you have already tried the standard software troubleshooting. Doing a factory reset should have reverted the firmware to stock, which may be the reason why hotspot and tethering work afterwards. Consider doing another round of factory reset and test these functions again right after wards. Make sure not to install any third party apps after doing a factory reset to help you identify if any of them is to blame.

If your Note 5’s hotspot is configured correctly (to allow other devices to identify and connect to it) but is not getting the expected result after a factory reset, you probably have a defective hardware to begin with. The hotspot and tethering functions are using a dedicated set of hardware components to work.

Have the checked, or better still, replaced if the problem continues to bug you.

Problem #2: Galaxy Note 5 Wi-Fi keeps on disconnecting

My issue is that I turn the Wi-Fi on and it connects perfectly to my Wi-Fi, but like a minute later it’ll automatically turn off and then back on. It’ll do this very often, so I’m not able to use the Wi-Fi on the phone at all. May that be on the software or on the hardware? — Jesus

Solution: Hi Jesus. There’s no way of telling what the cause might be unless you do some troubleshooting yourself. Below are the things that you can try to help you isolate whether you have a software or hardware issue at hand.

Boot the Note 5 in safe mode

Loading safe mode should be the first step as it does not involve doing much. You simply have to observe how the phone functions afterwards to know.

Safe mode is a special environment the forces the phone to run only first party or pre-installed apps. This means that anything you’ve installed after opening the box won’t be allowed to run while in safe mode. If a third party app interferes with the phone’s Wi-Fi function when it is running, this shouldn’t happen while your Note 5 is in safe mode.

Keep in mind that you still need to manually uninstall the problem app. Safe mode won’t tell you what the name of the app is. You must uninstall your apps individually until you are convinced that the issue is gone.

Below are the steps on how to do safe mode:

  • Turn off the phone completely.
  • Press and hold the Power key.
  • Once ‘Samsung Galaxy Note5’ shows, release the Power key and immediately press and hold the Volume Down button.
  • The phone will restart but keep the Volume Down button pressed.
  • Once the phone has finished restarting, ‘Safe mode’ will be display in the lower-left corner of the screen.
  • You may now release the Volume Down button.

Wipe the Note 5 cache partition

Once your Note 5 powers on and load the operating system, it creates sets of files associated with all the installed apps called cache. This cache is stored in a special section in the phone’s internal storage and is updated from time to time. This allows the phone to load apps more quickly and efficiently.

Cache partition also keeps update files as well as an assortment of temporarily data that the system needs. Overtime, the cache gets full and even corrupted. This can result to all sorts of problems and may or may not affect the core functions of your phone.

It is recommended that cache is deleted regularly to prevent complications. If you haven’t done this before, simply follow these steps:

  • Turn off your Samsung Galaxy Note 5 completely.
  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  • Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  • The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Perform a factory reset

As the name suggests, a factory reset will restore the defaults of your phone’s operating system. This procedure is helpful if safe mode and clearing the cache won’t make any difference. Factory reset deletes everything off the phone’s internal memory so make sure to create a copy of your personal data before doing it.

  • Turn off your Samsung Galaxy Note 5 completely.
  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  • Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  • When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  • The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

It’s always a good practice to hold off re-installing any of your other apps after a factory reset for sometime so you can observe if the problem remains. If nothing changes even after a factory reset, you are certain that there’s a hardware issue behind your Wi-Fi problem.

Consider having it replaced or checked.

Problem #3: Note 5 suffers from multiple problems after updating

Hi. Ever since I updated my phone. I am facing many issues.

1) Wi-Fi connection, whenever I press the Wi-Fi sign in the pull down panel or in settings. It will take at least 2 minutes or even more to connect to Wi-Fi. It was not like this in the kitkat version.

2) now when I screenshot there is no notification for me to share or edit in the pull down menu. Previously in kitkat when I do a screenshot I will be able to share it from the pull down panel.

3) whenever I make a call there will be call drop then I have to make the call again for it to get through.

4) currently when I plug in my ear piece there is no notification or most used apps in the pull down panel. In kit kat when I plug in my ear piece there will be a notification and I will be able to chose my most used apps from the panel.

I have already wipe the cache partition. But it has not resolved any of the issues. Please do let me know if there is any thing that can be done to resolve this. E.g reinstalling the new updates or going back to kit kat.

Thank you for your time. — Palaniappan

Solution: Hi Palaniappan. If these problems started to surface after an update, doing the standard software troubleshooting should help. Please do a factory reset if wiping the cache partition doesn’t help.

Keep in mind that apps can also cause problems so make sure to check if any of them is the reason for any or all these issues.

For numbers 2 and 4, there’s really nothing much that you can do as Lollipop tons of changes especially on the notifications aspect. Lollipop is cosmetically different from KitKat as well so you can expect to lose some of the features that may be identified with KitKat.

We don’t think anybody has created a way to downgrade a Note 5 to KitKat. While reverting to KitKat may be possible for older devices, the newer Samsung phones and tablets like the Note 5 and the S6 series that released with Lollipop don’t enjoy that option at this time.

Problem #4: T-Mobile Galaxy Note 5 keeps getting disconnected from LTE network

I bought a Galaxy Note 5 through Amazon. It was working perfectly fine for the first few weeks and up until recently, I’ve had several problems with connectivity to the network. When I disconnect from the Wi-Fi at home, it often (but not always) won’t connect to the T-Mobile network (it is a T-Mobile branded phone). Not even restarting it several times works. I’ll put it in airplane mode and then turn airplane mode off and sometimes that works. Today, I left home and it was connected to the T-Mobile network, but my data won’t turn on. It flashes 4G LTE for a second and then turns off. I went to status and it says I’m connected to LTE, but I’m not getting any data coverage whatsoever. I can however text and call. — Nathan

Solution: Hi Nathan. If the problem comes and goes, start by doing a factory reset. This will ensure that the system cache will be fresh and apps restored to their default state.

You can also try to verify if the issue is with the SIM card by inserting it to another LTE-capable device. A faulty SIM card can manifest in many ways but the most common is a random drop in connectivity. Needless to say, it’s also a good way to check if the problem is carrier network related.

Mobile network connectivity issues are best addressed by your carrier as they have access to information that you don’t. Outages or intermittent network problems may not be made known to subscribers. Asking direct support from T-Mobile may also save you from doing other troubleshooting.
