How To Fix Samsung Galaxy Note 9 Does Not Automatically Connect To Mobile Data Network

Problem: Hi, I am using a Samsung Note 9 connected to the Verizon network. Trying to be succinct, here is the issue. Phone works properly while connected to wifi at home. When away from wifi the phone will not connect to the mobile Version network until wifi is turned off and the phone is restarted. It then works on the mobile network fine. Once back home wifi just gets turned back on and connects and works as it should. Want to see if it can be configured to find wifi at home and mobile away without the turning off of wifi and restarting for mobile connect. Thanks and Merry Christmas

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

Do a soft reset

The first thing you will need to do in this case is a soft reset which should fix minor software related glitches such as this.

  • Press and hold the Power and Volume down key for up to 45 seconds.
  • Wait as the device restarts.

Once this is done try to check if the issue still occurs.

Try going to a different location

Sometimes you will be in an area that will not have a strong mobile data network coverage which is one reason why the phone will have difficulty connecting to the mobile data network. To check if this is what’s causing the problem try going to a different area that’s  known to have a good signal.

Reset network settings

This will reset all of the phone data connection settings to its out of the box defaults. You might need to setup the APN settings of the phone again once this is complete.  Take note that when you perform this step the following will occur:

  • Stored Wi-Fi networks will be deleted.
  • Paired Bluetooth devices will be deleted.
  • Background data sync settings will be turned on.
  • Data restrictive settings in applications that were manually turned on/off by the customer will be reset to the default setting.
  • Network selection mode will be set to automatic.

To perform this step do the following:

  • 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.

Check if the issue still occurs.

Check if the issue occurs in Safe Mode

There are cases when a third party app you downloaded will cause issues on the phone when they are installed. To check if an app you downloaded is causing the problem you will have to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

  • Turn the device off.
  • Press and hold the Power key past the model name screen appearing on the screen.
  • When SAMSUNG appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

In case the issue does not occur in this mode then it is most likely caused by an app you installed. Find out what app this is and uninstall it.

Wipe the cache partition of the phone

There are instances when the cached data stored in the dedicated partition of the phone can become corrupted. When this happens this this will usually cause certain issues to occur on the phone. To eliminate the possibility that this is what’s causing the problem you will have to wipe the cache partition of the phone from the recovery mode.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • When the Android logo displays, release all three keys.
  • An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  • Press the Volume down key several times to highlight wipe cache partition.
  • Press Power key to select.
  • Press the Volume down key to highlight yes, them and press the Power key to select.
  • When the wipe cache partition is complete, Reboot system now is highlighted.
  • Press the Power key to restart the device.
  • Check if the issue still occurs.

Perform a factory reset

In case the above steps fails to fix the problem then chances are this is caused by a software glitch. The best way to deal with this right now is to perform a factory reset. Make sure to backup your phone data before doing the reset.

  • Turn off the phone.
  • Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  • 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).
  • Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.
  • Check if the issue still occurs.
