How to fix your Galaxy Note5 if apps keep crashing [troubleshooting guide]

Another common issue that many #GalaxyNote5 owners have encountered is about apps crashing for no reason at all. If you are one of the unlucky users who happen to have this issue, this troubleshooting may help.

Problem #1: What to do if Galaxy Note5 phone number exists in two networks after porting

Warning brace yourself for this epic event. I first bought a phone and certain new service plan through Total Wireless. I had it out 2 months and then I went to upgrade so I chose the option to bring my own phone to Straight Talk and I bought the Sim kit with it. all I wanted to do was simply Port my cell phone number from Total Wireless to Straight Talk, even though Total Wireless is a sister company to Straight Talk, believe it or not. Then tell me why that this is day 10 going in today 11 that the number is ported over successfully apparently but I have the same telephone number for two different phones through two different providers? The phone’s pick out what numbers that they will accept and what numbers I can receive from one phone to the other. I can even call myself from one phone to another how is that possible. I’ve talked to numerous countless disrespectful customer service agents even managers been on the phone for hour and a half at the max and get hung up on. Sincerely one disgusted irritated don’t know what to do next Consumer.

Solution: Total Wireless and Straight Talk may be considered sister companies in some sense but their each of their systems are separate from one another. Total Wireless has its own set of network infrastructure, support and everything else. The same is true for Straight Talk. If you simply asked Straight Talk to port your Total Wireless number to their network without deactivating it with Total Wireless first, this is the reason for your situation right now. In other words, telling Straight Talk that you want to use a particular number does not automatically deactivate that number from Total Wireless’ system. Your Total Wireless account or number must still be active and since there was no reason for Total Wireless to deactivate it, it remains active. What you need to do is simple: talk to Total Wireless and let them deactivate your account. It may take effect immediately or a few days so be sure to ask them for information so you’ll know.

Problem #2: Galaxy Note5 won’t send SMS: how to change the Message center number

I just switched from Verizon to Consumer Cellular, and I can receive but not send text messages. On your May post, you told the person it is probably the message center number and to “go to the dialer and enter *#*#4636#*#*. If all goes well you should be brought to a hidden menu setting on your phone.”  All did _not_ go well; I get a number not in service message. Is there another route to try?

Solution: Access to hidden service menu is originally designed by Samsung for qualified technicians only. In order to avoid average users from messing the system, carriers may block them from accessing the service menu on carrier-branded Samsung phones. If typing *#*#4636#*#* on your phone’s dialer yields nothing, then your carrier must have disabled this service menu access. To change the Message Center Number (MCN), try these steps:

  1. Open Samsung Messages app.
  2. Tap More settings at the upper right (three-dot icon).
  3. Select Settings.
  4. Tap More settings.
  5. Tap Text messages.
  6. Select Message center to edit it.
  7. Tap Set to confirm the change.
  8. Restart the phone.

Problem #3: How to fix your Galaxy Note5 if apps keep crashing

All forms of apps on my device force close themselves after a certain period of time. All my social media apps stop pushing notifications. I have turned off the doze feature as well any other feature that would close an app to save battery. There’s no antivirus or ram cleaner installed either. The apps just close if I turn off the screen and even when the screen is on, if I switch between two apps, the previous one force closes either immediately or after some time.

Solution: There are  a number of possible reasons why apps on your Note5 may be doing this. Some of the common reasons include the following:

  • bad third party app
  • unknown software glitch
  • bad battery
  • Hardware malfunction

What to do if app on your Galaxy Note5 keep crashing

Based on the possible causes above, these are the things that you can do to fix the issue on your end:

Solution #1: Recalibrate the battery and Android

We recommend that you try to recalibrate the battery and operating system first. Android may sometimes lose track of actual battery levels after some time, which can then lead to premature reboots. To ensure that the operating system detects the correct battery readings, follow these steps to recalibrate it:

  1. Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
  2. Charge the phone until it reaches 100%. Be sure to use original charging equipment for your device and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
  3. After the elapsed time, unplug your device.
  4. Restart the device.
  5. Use your phone until it completely runs out of power again.
  6. Repeat steps 1-5.

Solution #2: Check for bad third party apps

If nothing works after you recalibrated the battery and the OS, the next troubleshooting to do is to check for the possibility that a bad third party app may be causing it. To do that, you need to restart your Note5 to safe mode. It is an independent software environment used by technicians to see if there’s a bad third party app that interferes with Android. Safe mode only blocks third party apps so apps that came with the operating system (preinstalled apps) are expected to work. Here’s how to do it:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Observe the phone while it’s on safe mode and check if apps continue to crash.

If pre-installed apps work, it’s possible that one of your downloaded apps is causing the problem. To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your Note5 is still problematic, repeat steps 1-4.

Solution #3: Factory reset

Have you tried doing a factory reset? This is a necessary troubleshooting step in this situation especially since you’re having trouble with all apps. We’re thinking of a possible Android issue so factory resetting the device may help.

To factory reset your Note5:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.
  10. Let the phone run for 24 hours without adding any apps.

Solution #4: Send in the phone

Should nothing work after doing all the steps above, there must be something wrong with the hardware. It can be due to a battery problem or a motherboard malfunction. To resolve your issue, you must let Samsung check the hardware.
