How To Fix Samsung Galaxy Note 9 Notifications Not Showing After Software Update

Problem: I got a real noodle twister.  With Wifi on a non-broadcast SSID the Note 9 will connect if you setup the connection.  After that it will not reconnect. Go out of range and come back – no connection, turn off wifi turn it back on – no connection, airplane mode off then back on – no connection.  Turn on a broadcast SSID poof connects every time no issue. I have a Note 4, no issues, Note 2014, no issues, Note 3, no issues, Note 8, no issues, only the Note 9 won’t freely connect to the non-broadcast SSID.

I have tried:

Reset network connection – no luck

Delete and re-input connection – no luck

Wipe system cache – no luck

Factory reset – no luck

Applied Patches – no luck

Rebooted switch – no luck

Change from N to AC, etc. – no luck

Reboot phone – no luck

Have any of you had any experience with this?  By the way this is a brand new phone as done this since it came out of the box.

Solution:  Before performing any troubleshooting steps on this phone it’s best to make sure that the phone is running on the latest software version. If an update is available then download and install it first.

We have had another reader who sent us this same issue last week however it is happening on an A9 which is also a new device. This makes us suspect that this might be caused by a software glitch and should be fixed by a future minor update. You can however perform the troubleshooting steps listed below which are recommended for this particular problem.

To connect to a hidden Wi-Fi network you will need to manually add this network to your phone.

  • From a Home screen, swipe up or down from the center of the display to access the apps screen.
  • Go to Settings – Connections – Wi-Fi.
  • Make sure the Wi-Fi switch (upper-right) is turned on.
  • Tap Add network
  • From the Network name field, enter the appropriate name.
  • From the Security field, tap the Dropdown menu icon then tap the appropriate security option: None, WEP, WPA/WPA2/FT PSK, 802.1x EAP
  • From the Password field, enter the appropriate password.
  • Ensure additional settings (e.g., EAP method, CA certificate, etc.) are configured appropriately (if applicable) then tap SAVE

If the phone does not connect automatically to this hidden network the next time it tries to then proceed with the troubleshooting steps listed below.

Reboot the router

Just like any other electronic device a restart will refresh the software of the router and will usually fix minor issues.

Update the router firmware version

You should make sure that the router is using the latest firmware version as this will usually have fewer bugs than the older firmware. You will have to refer to the router manual on how to update this device.

Make sure the router settings are correct

There are cases when the problem is caused by a setting in the router. Refer to the router manual on how to properly set the device. Things to check are the power output, firewall, and other security settings.

Factory reset the router

If you have administrative access to the router then try performing a factory reset on the device. Refer the router manual on how to perform this step.

Once you have eliminated the router as a possible cause to the problem it’s time to troubleshoot the phone.

Reset the network settings

By performing this step you are wiping  the network configuration including saved Wi-Fi networks of the phone.

  • From the Home screen, swipe up on an empty spot to open the Apps tray.
  • Tap Settings – General Management – Reset – Reset network settings.
  • Tap Reset settings.
  • If you have set up a PIN, enter it.
  • Tap Reset settings. Once complete a confirmation window will appear.

Once this is done check if the issue still occurs.

Check if the problem occurs in Safe Mode

A good way to check if a third party app is causing this problem is by starting the phone in Safe Mode. When the phone runs in this mode only the pre-installed apps are allowed to start making it easier to determine if an app you downloaded is the culprit.

  • With the phone turned on press the turned on start pressing the Power button.
  • If the menu pops up tap Power off and tap the option to open Safe mode.
  • Wait for a few moments.
  • The device is now booted in Safe Mode

In case the issue does not occur in this mode then you should find out what app is causing the problem then uninstall it.

Wipe the cache partition

The cached data stored in the dedicated partition of the phone can sometimes get corrupted. When this happens certain issues can occur. This issue that the phone is experiencing right now could be caused by a corrupted cached data. To check if this is the case you should wipe the cache partition of the phone from the recovery mode.

  • Turn off your device.
  • Now Press and hold the Bixby, Volume Up and Power buttons for few secs.
  • After you see the Android Logo is displayed, release the Power and Bixby button, but keep holding the Volume Up button until the Recovery Mode screen shows up
  • Now you can see the Android System Recovery Menu option.
  • Use volume keys to highlight wipe cache partition and use the power button to select it
  • Confirm by selecting yes option

Perform a factory reset

One last troubleshooting step to consider is a factory reset. This will revert your phone back to its original factory condition. Make sure to backup your phone data as it will be erased in the process.

  • Go to  settings of your phone.
  • Now Scroll down and select General management option
  • Tap on Reset option
  • Choose  Factory data reset
  • Select the option ‘Erase everything’ and then wait till your device gets rebooted with the factory settings.

Once the reset is complete do not install any apps in your phone just yet. Try to check first if the issue still occurs. In case it does then you should contact Samsung regarding this matter as it is most likely caused by a software bug.
