How To Fix Galaxy S9 Call Issues

Some of the issues are due to network problems either with your carrier (ATT, Verizon, etc.) or with software/hardware on your phone. No matter the case here are the 11 easy ways to troubleshoot and fix the problem.


Sometimes all it takes is a simple restart to fix most software glitches. Go ahead and restart your Galaxy S9 and check to see if the problem still occurs.

Airplane Mode

Do you have Airplane Mode turned on? Airplane Mode prevents any and all network communications. Hence, your smartphone won’t be able to connect to your carrier’s network.

All you have to do is pull down the notification center and ensure that the Airplane icon is not highlighted.

Carrier Updates

Check to see if you missed any important updates from your carrier. To do so, go to Settings > Software update to see if there is an update. You can tap Download updates manually to check.

Phone App Data

  • Open Settings either through your notification bar (drop-down) or through the Settings app in your app drawer.
  • Tap Apps.
  • Tap More settings (three-dot icon) at the upper right.
  • Tap Show system apps.
  • Look for the Phone app and tap it.
  • A list of stuff of information about the app, including Storage, Permissions, Memory Use, and more appears. These are all clickable items. Click on Storage.
  • Check if your S9 makes calls without cutting out.

Please note that the above method erases your call logs. If you want to save the logs backup your information using your phone’s backup & restore feature.

SIM Card

Turn off your Galaxy S9 and remove the SIM card. After, reinsert the SIM into your Galaxy S9 (turn it on after) and check to see your phone calls go through successfully.

Reset Network Settings

  • Open the Settings app.
  • Tap General management.
  • Tap Reset.
  • Tap Reset network settings.
  • Tap RESET SETTINGS button.
  • Restart your S9 and check how it works during calls.

Please be aware that the above clear wifi, mobile data, and Bluetooth settings. You must reconfigure these after the reset.

Safe Mode

If you suspect that an app is causing issues with your Phone app then restart your Galaxy S9 in safe mode. Once you do this, only the apps that came with your phone remain.

Test to see if your phone makes calls successfully. If it does then you know that there’s an app installed that’s causing interference. Delete apps one by one and check to see if the S9 makes calls after each app uninstall.

Factory Reset

Your last resort is to factory reset your Galaxy S9. However, be aware that this deletes all the information on your phone and restores it to the default settings that came with the device.

You lose all photos, files, apps, and settings that you added to the phone after purchase. Take some time to back up contacts, photos, and other files as needed.

Final Thoughts

If after all that your Samsung Galaxy S9 still keeps dropping calls, its time to take your phone to your carrier and have them fix the issue or replace the phone. If it is a hardware issue and you’re out of warranty then you may need to pay to have your phone fixed at a Samsung repair center or other tech repair shop.
