Problem 1: Galaxy Note 5 from Canada can’t roam in the US

I am a snowbird in the US from Canada. I am using an unlocked Samsung Galaxy Note 5 from Canada with a Roam Mobility SIM card for the USA. I have used a different roam mobility card last year with no problems. However this year my data will not function even after changing my APN to the required Roam Mobility settings. My sister also is using a Roam mobility sim card (the same one she used last year) on her Samsung S6 and cannot access wifi anywhere. We are using the same condo as last year. Nothing has changed, password etc. We can get wifi on our computers but not on our cells? I can’t get even data on my phone and did a factory reset to try and get it working. It won’t even recognize my location. HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! — Darlene

Solution: Hi Darlene. We suggest that you talk to your carrier about this issue since it involves roaming, a feature that must be enabled first. Normally, you have to let your carrier do the required modifications to your account and in your device so roaming is activated. They have to do it while you’re still in their network. If you haven’t done this before leaving Canada, there’s a chance that this is not a phone issue at all. This may be the reason why nothing changed after you tried to factory reset your device.

We don’t know if your carrier can remotely do the necessary changes now that you’re already in the USA but we still highly recommend that you contact them.

Problem 2: Galaxy Note 5 wifi won’t switch back on

Hello man! My Galaxy Note 5 isn’t able to connect to any Wifi. The Wifi logo lights up only to a dim green and the Wifi switch can’t be switched on (in the Settings). The only thing I can see from the Wifi settings is the “Smart network switch.”I am able to connect to the Wifi about a few times only after some random resets by the phone (another problem haha)… But I hope you could help me solve the problem about the Wifi since I need to connect to the internet from time to time. Thanks! — Dan

Solution: Hi Dan. Wifi functionality can malfunction for a number of reasons, including a possible hardware issue. To troubleshoot the problem, follow our suggestions below:

Clear the cache partition

Cache partition is a part of the storage device that keeps an important set of cache called system cache. System cache is a collection of temporary files that Android uses to load apps quickly. If this cache gets corrupted or out-of-date, it can sometimes lead to some features or functions to work erratically. If you haven’t tried it yet, be sure to refresh it by doing the steps below:

  1. Turn off your Samsung Galaxy Note 5 completely.
  2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  4. Once the Android logo shows, release both the Volume Up and Home buttons.
  5. 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.
  6. Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
  7. 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.
  8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

See if a third party app is to blame

The next troubleshooting step that you must perform is to verify if a third party app is causing the problem. While in safe mode, your Note 5 will only allow pre-installed apps to run. Everything else that you’ve added won’t load so it’s a good way to know if our suspicion is right. In other words, if wifi functions normally when your device is in safe mode only, that’s a clear sign that an app is causing it.

To boot your phone to safe mode, follow these steps:

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

Do a factory reset

Another good troubleshooting step that you can do is to wipe the phone clean and restore all software settings back to their defaults. It’s the most that you can do given the situation you’re in. In its factory state, your phone’s wifi is supposed to work normally. To factory reset your device, kindly do these steps:

  1. Turn off your Samsung Galaxy Note 5 completely.
  2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  4. Once the Android logo shows, release both the Volume Up and Home buttons.
  5. 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.
  6. Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  7. 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.
  8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Send the phone in for repair

If all the troubleshooting steps above won’t work at all, that means your phone has a hardware issue. Its physical antenna may be broken, or one of its chips involved in network processes is malfunctioning. To fix the problem, you must have the phone repaired. Contact Samsung and let them take a look at it.

Problem 3: Galaxy Note 5 won’t connect to all wifi networks

I have a 2-year old Samsung Note 5 and started running into wireless network connectivity problems about 6 months ago. For all wireless networks that the phone already recognizes, it connects automatically. For nearly all (not 100%, but probably 75%) new wireless networks, the phone simply will not connect. At times, after placing the phone on airplane mode and attempting to connect to wireless networks, it will connect for a flash of a second and then immediately disconnect. This is where the Failed to Connect to Wireless network sign continues to appear. I’ve tried all the airplane mode tricks and App updates and hard phone re-sets that I can think of. Would love any other suggestions you might have. Thanks! — Rob

Solution: Hi Rob. Due to lack of history about your device, it’s not that obvious to us as well why your Note 5 behaves this way. Like any other issue in this post, it may be brought about by a poorly coded app, an operating system glitch, or even by a bad hardware. Be sure to follow our suggested troubleshooting steps for Dan above to fix it.
