Note 4 Not Registered To Network When Making A Call

Problem: Suddenly my phone started to restarting and then the fingerprint scanner disabled. So I did factory reset and after that when I try to make call it saying that I’m not registered to network. But when I turn the phone off and turn on then the carrier icon will appear then few seconds it disappear with saying no service. Before the issue the phone was working correctly

Solution: One of the reasons why you get a no registered to network error message when making a call is because the phone software is not updated. Try to check if this is the case by manually checking for a software update and installing it in your phone if available.

Another factor that can cause this problem is if your phone has a null or invalid IMEI number. Try checking the  phone’s IMEI number by opening the dialer then pressing *#06#. If you get a IMEI Null or 000000 then follow the troubleshooting steps listed below.

  • From the phone dialer type- *#197328640# or *#*#197328640#*#*
  • From the Command Mode Select on Common, normally option 6
  • Select (FTM) Option 1. This is the debugging or field test mode.
  • If (FTM) is on, then turn this OFF
  • As soon as you turned this off your NULL or altered IMEI number will be restored
  • From the  Command screen, press the Menu key, the button that’s found left of the Home button.
  • Select Key input and enter option 2 to turn off FTM.
  • Wait for a minute for the FTM to turn off then remove the battery and SIM and leave it out for two minutes.
  • Reinsert just the battery
  • Turn on your phone then enter the command mode again dial – *#197328640#
  • Select the Debug Screen, normally option 1
  • Choose phone control, option 8
  • Click on nas control, option 3
  • Click “RRC (HSDPA), option 5
  • Click RRC revision, option 2
  • Choose option 5 (HSDPA only)
  • Turn off your phone  and insert your Sim card
  • Turn on the phone

In case your phone has the correct IMEI information then follow the steps listed below.

  • Turn off the phone
  • Remove both the battery and the SIM
  • Press and hold the power and home button for at least a minute.
  • Reinsert the battery and SIM
  • Turn on your phone.

If the above troubleshooting steps fail to fix the issue then you should try using a different SIM card in your device.

Note 4 Can’t Place Or Receive Phone Calls

Problem: My Note 4 lost its ability  to place or receive  calls.  I performed All master reset options, changed the SIM card, replaced the motherboard,  and antenna.  Phone functions  normally  until  I attempt  to call, no network  connection  appears on the screen, and the signal  bar were gone until  recently? No error  codes but it behaved this  way with both motherboards?

Solution: This appears to be a hardware issue already. Since you have performed most of the troubleshooting steps already I suggest you have your phone checked at an authorized service center. The technician may be able to find out what exactly is wrong with your device.

Note 4 Reboots when Call Is Received

Problem: Since updated to marshmallow I will receive a call and the phone shuts off and reboots. Also, I will receive a text and a message briefly reads “unfortunately messages has stopped”  My carrier is US Cellular.

Solution: Try to check if the phone shuts down when receiving a call when it is connected to its wall charger. If it doesn’t then the problem could be caused by a faulty battery that’s straining to provide extra power to the phone whenever a call arrives. Try replacing the battery with a new one and see if this fixes the problem.

If the problem still occurs even when the phone is connected to its charger then you need to backup your phone data and do a factory reset. This is a highly recommended step that needs to be done whenever issues occur right after an update. What this does is it deletes the old software data from your phone that could still be present in the device and is causing a conflict with the new software version. This step will also resolve the message issue that you are experiencing with the device.

Note 4 Not Making Or Receiving Calls

Problem: Loss of network connection.  I first replaced the SIMPLE card, performed all forms of reset, then shipped to manufacturer. They returned it and the paper simply said no network connection. Now i’ve replaced  the motherboard  and antenna  but problem persist. Phone does everything  but place  or receive calls and when I enter the code on the keypad to turn on the cell radio nothing happens, please help?

Solution: Try using a different SIM card in your device then check if the issue still occurs. If it does then the problem could be with the phone itself. If you check one of the issues we addressed above then you will find out that this is quite similar. The troubleshooting step that you will need to follow is the checking of the IMEI. If your phone has a null or no IMEI number then this could be the reason why it is not connecting to the network. Try to perform the troubleshooting steps listed above to get back the IMEI number of your device.

If the issue remains unresolved then you will have to bring your device to an authorized service center and have it checked.

Note 4 Random Drop Calls

Problem: Device one year old, superb until recently, now getting voice drop out for 10 to 20 secs and sometimes call disconnects. Very random not every call but enough to be frustrating

Solution: The first thing you need to check in this case is the network. To do this verify if the issue occurs in one particular area or if it occurs in different locations. If you only experience the problem in let’s say your house then this could be a network or signal related problem. Contact your carrier regarding this matter.

If the problem occurs even in other locations then this is most likely a phone related issue. Follow the troubleshooting steps listed below to fix this problem. Move to the next step if the issue still occurs.

  • Start the phone in recovery mode then wipe its cache partition. Restart the phone then check if the issue still occurs.
  • Start your phone in Safe Mode. Check if the issue occurs in this mode. If it doesn’t then an app installed in your phone could be causing the problem. Find out what app this is and uninstall it.
  • Backup your phone data then do a factory reset.

Note 4 Can’t Hear Calls

Problem: I bought a used Galaxy 4 and sent it to my wife (she is out of town).  She is having difficulty hearing me on the earpiece.  She can hear me fine on the speaker.  Again, she is out of town so I cannot try to fix the problem myself. She has, however, looked at any adjustment options but still no improvement. What do you suggest?

Solution: If your wife has already set the volume to maximum and the earpiece volume is still low then this could be a problem with the earpiece. You should however try to check if the phone software is causing this issue by backing up the phone data then doing a factory reset. Once the reset is complete try to check the call volume again. If it is still low then you may need to have the earpiece replaced. Have this checked at an authorized service center.
