S9 Drops Calls After Connection Is Made

Problem: The problem with my s9 Samsung smartphone is that on a lot of different contacts on the phone when I try to make a call to them it drops the call about a second after the connection is made. This only happens to some of the contacts on my phone; others work fine. Is there anything I can do to change the setting on those ones that drop off or is this something I ‘m going to have to take it to the ATT store and let them look at it.

Solution: The first thing that you will need to do in this case is to eliminate any network related issues that could be causing the problem by following the troubleshooting steps listed below.

  • Try going to a different area where the phone gets a strong network signal and check if the issue still occurs. If it doesn’t then the problem might be caused by a low network signal.
  • Try inserting your SIM card in a different phone then check if the issue still occurs. If it does then the problem might be caused by a faulty SIM card.

In case the issue is not caused by the network or SIM card then it’s time to troubleshoot the phone by following the troubleshooting steps listed below.

  • Check if the issue occurs when the phone is started in Safe Mode. If it doesn’t then the problem could be caused by an app you downloaded. Find out what app this is and uninstall it.
  • Try wiping the cache partition of the phone from the recovery mode.
  • Backup your phone data then do a factory reset.

If the above steps fails to fix the problem then you should take the phone to the AT&T store and have it checked.

S9 Cannot Make Or Receive Calls

Problem: Hello, I just landed in South Korea and I put a new Korean sim card in my phone. The mobile data is working normally but I cannot receive or sent text or calls. Would you please help me ? We tried to restart the phone 10 times already. I checked the safe mode too. They told me it might be because my phone was bought outside of Korea. But it doesn’t make sense that the data is working and not calls or text. On the apn details, it seems that some information are missing. So it may be one of these reasons. Thank you

Solution: The network that the phone is connected to right now might be using a different network mode for calls and texts that is not supported by your phone.

The S9 is capable of supporting the following bands

  • GSM 850 / 900 / 1800 / 1900
  • CDMA 800 / 1900
  • HSDPA 850 / 900 / 1700(AWS) / 1900 / 2100
  • CDMA2000 1xEV-DO
  • LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 13(700), 17(700), 18(800), 19(800), 20(800), 25(1900), 26(850), 28(700), 32(1500), 38(2600), 39(1900), 40(2300), 41(2500), 66(1700/2100)
  • LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 13(700), 14(700), 17(700), 18(800), 19(800), 20(800), 25(1900), 26(850), 28(700), 29(700), 30(2300), 38(2600), 39(1900), 40(2300), 41(2500), 46, 66(1700/2100), 71(600)

Try to check which network mode is being used by the carrier and if it is not supported by the phone then I suggest you switch carriers.

You should also get the APN settings of your carrier and make sure to input this in your device.

S9 No Sound When Making Calls

Problem: I have an S9 phone and the issue that it has been giving me is primarily to do with audio i believe. Whilst i can play music through a bluetooth speaker i cannot use wired headphones or make calls or speakerphone on the device. I have tried factory resetting the phone and using it in safe mode. I have used the Sim card in other phones and had no issues with the sim. There have been times where the device will let me watch videos with sound (vary rarely) but once the device has run out of power or turned off it will stop the next time i use the phone. Often when i play videos it will crash or say that it cannot play the video but i can cast to a tv and it will play fine. The biggest issue is i cannot make calls because there is no sound and the receiving person cannot hear me either on speaker phone, Through a bluetooth device.or through the phone normally. When i make a call the phone almost freezes and takes up to a minute before displaying the call on screen. I have reset the phone app and removed most apps from my phone.

Solution: The best thing you can do right now is to backup your phone data then do a factory reset. Once the reset is complete do not install any apps in your phone yet. Try to check if the issue still occurs. If it does then this is most likely caused by a faulty hardware component. The best thing to do right now is to bring the phone to a service center and have it checked.
