Problem 1: AT&T Galaxy Note 5 mobile data won’t work with MOVICEL network

Good morning gents. Please help, because I’m getting frustrated with this Galaxy Note 5 I’ve just bought from someone that came from the US.

One can make phone calls and send SMS without a problem, using a local carrier’s SIM card.. The problem is data: I can only get data though WIFI, but NOT from the carrier’s  network. I’m using a local SIM card, and have a valid subscription for both voice and data; and the SIM will work perfectly well on any other local phone (That includes data). The phone in question has a lot of AT&T applications installed in it, although the phone is brand new. But I cannot get the phone to send or receive data from the MOVICEL carrier(one of my local carriers). In fact, one does not find the usual WCDMA/GSM/LTE menu in the the settings/more networks/Mobile networks, This MOVICEL does not have 4G/LTE. So is the phone carrier-branded? Is AT&T just operating phones in 4G/LTE? If so how can I get this phone to work on my WCDMA/GSM which just works on 2G/3G/+H protocols. Please help. — Jmaria.pvt

Solution: Hi Jmaria.pvt. If you can see AT&T apps, logos (both in the cover and when restarting), your phone is definitely a carrier-branded device. This means that you may or may not be able to use if for mobile data. Some carrier’s lock mobile data service to their network that there’s no way to use said function in other networks. At times, even rooting the device and doing the necessary follow up modifications are not enough. In other cases, simply changing the APN settings can work so make sure that you try that. If you don’t know the APN settings, contact your carrier to get the details. Without the correct APN settings, 2G, 3G and 4G data connection will not work.

If your phone already runs the correct APN settings at this time but it still is unable to use mobile data, there must be a deeper reason for it. One such reason is software incompatibility, which means that the phone’s operating system, which is an AT&T firmware, won’t work with your carrier’s network. Continue working with your carrier and see if there’s something that they can do to help. Otherwise, you’ll simply accept the fact that this phone is only good for SMS and voice calling.

Problem 2: Galaxy Note 5 wifi not working, wifi button is stuck

I have a Samsung Galaxy Note 5. My wifi stuck on turning on/dim green. I have tried to restart the phone but its not working, my bluetooth is working fine and all other things; it’s just the wifi.

Also, there are some instances that the wifi would turn on, but if you turn it back off it does the same thing. — Joseph

Solution: Hi Joseph. Did you do anything different prior to noticing the problem? If you did, undoing it may fix the issue. For example, if the problem occurred after you installed an app, it’s possible that said app may be buggy and causes the problem. Try to see if removing it from the system will help.

If you never did anything different and the issue happened all of a sudden,try doing the usual set of software troubleshooting to fix the issue.

The first one is to wipe the cache partition. Your phone uses a special set of cache called system cache to load apps quickly. This cache is kept in the cache partition. Sometimes, installation of new apps or Android updates can corrupt it, which in turn can lead to problems.  There’s no telling what the true state of the cache partition is at this time but it’s definitely worth checking. Making sure that the phone’s system cache is a good first step for this kind of issue. Here’s how to clear the cache partition:

  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.

If nothing changes after refreshing the cache partition, the next logical step for you is to see if the problem is being caused by a third party app. To do that, you need to observe the phone while it’s on safe mode. Here’s how:

  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.

Remember, safe mode is not a solution but a way for you to know if one of the apps is problematic. If your phone’s wifi works while it’s on safe mode, that’s a clear indication that our suspicion is right. To fix the issue, you must use the process of elimination in narrowing down the causes. Uninstall apps one by one by make sure that you observe how wifi works after every uninstallation.

If the problem continues even when the phone is in safe mode, you should consider doing a factory reset. This will accomplish the following:

  • erase any possible operating system bug
  • return all software settings back to their defaults
  • remove possible app causing the problem
  • eliminate possible modem firmware bug

If you haven’t tried doing a factory reset before, kindly do these steps:

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

Remember, factory reset as well as the other steps above only address possible software problems. If wifi continues to be problematic after a factory reset, that’s an indication that there’s a deeper reason for it, most probably a hardware malfunction. Contact Samsung or your carrier to have the phone repaired or replaced.

Problem 3: Galaxy Note 5 lost mobile data connection after installing update

After installing the newest software update, I am having mobile data network issues. To be more specific, I have no Internet/Mobile network. I have Tracfone running on the AT&T network. Device is Samsung Galaxy Note 5. I currently have over 2GB in my data bank. My mobile data is enabled. I have at least 3 bars of signal as I’ve tried opening internet browser or Facebook or some other mobile data dependent app, usually 4 to 5 bars. I’ve tried turning phone off, soft reset, tweaking APN settings (I reverted back to default after it didn’t fix the problem), made sure airplane mode is off, turned mobile data off then back on…. almost everything I can think of and a few tips from Web searches. I can make and receive texts and calls and WiFi works fine. What else can I do? The last resort seems to be factory reset but I’m not sure how and am afraid to lose data. — Andrea M

Solution: Hi Andrea. It’s hard to tell what really is going on with your device since we don’t know its full history. If you are positive that the problem occurred only after installing an update, you should really try a factory reset first so you’ll know if you can fix the problem on your level. If it won’t work, that’s the time that you contact your carrier for support. There may be a bug in the latest firmware from them that causes the problem so they may or may not have the a ready answer for you.

Problem 4: Galaxy Note 5 wifi won’t turn on after a factory reset

So, my son’s Samsung Galaxy Note 5 will not connect to wifi or any mobile hotspot. I have done all the different steps you’ve shown me how. to the point i did a factory reset because nothing worked. Now it’s wiped it all and it’s prompting me to start all over as if the phone was brand new and still will not connect to wifi. I try to turn on and it won’t at all. I think it may need a software update but can’t do it because there is no wifi/hotspot connection, what else can i do? — Cesarhugog12

Solution: Hi Cesarhugog12. As mentioned above, if wifi functionality continues to fail even after a factory reset, you should consider repair or replacement. Wifi function is handled by a certain hardware chip and if that part is malfunctioning, it can lead to the problem you have.
