How to troubleshoot Galaxy A7 2018 that can’t make / receive phone calls

Don’t forget to make a test call to know if the problem is fixed or not after performing each solution.

First solution: Force close Phone app then reboot your phone.

Random glitches affecting the Phone app are usually the underlying cause. The good thing is that this can easily be remedied by clearing the app and restarting the device. That said, this should be the first workaround to try. Here’s how it’s done:

  1. Launch the Recent apps menu/key. A list of running apps preview will then appear.
  2. Tap and hold on the Phone/Dialer app then swipe it to the right. Doing so will end the process or app from running and free up some space of your phone’s internal memory.
  3. Alternatively, you can navigate to Settings-> Application Manager-> All apps-> then scroll to the Phone/Dialer app.
  4. Tap on the app, then tap Force Stop option to end the process.

To dump cache files from the phone memory, perform a soft reset or turn your phone off for a few seconds and then back on again.

Second solution: Toggle Airplane mode on and off again.

Turning Airplane Mode or Flight Mode is another way of restarting network services on your device. When enabled, calling, messaging and data network features including Wi-Fi and Bluetooth are automatically turned off. This trick has been proven effective by many ever since the feature became available. Should you wish to give it a shot, follow these steps:

  1. Tap Apps from the Home screen.
  2. Tap Settings.
  3. Tap Flight Mode or Airplane Mode under Connections section.
  4. Tap the slider to turn Airplane Mode on for about 30 seconds.
  5. After the elapsed time, tap the slider again to turn Airplane Mode off.

Try and see if that does wonder to you as well. Otherwise, try other applicable solutions.

Third solution: Manage call settings and relevant features.

There are certain features that when enabled prevent incoming calls from going through. That said, try to check if call barring and call divert features are enabled on your phone. If necessary, disable or turn them off then see if you can receive calls with these features turned off.

To turn call barring off or on, follow these steps:

  1. Open the Phone app.
  2. Then tap the Menu icon or three vertical dots on the upper-right corner or the screen.
  3. Tap Settings from the given options.
  4. Scroll down to More settings then tap Call Forwarding from the given options.
  5. If necessary, disable it and then do a test call.

To turn call divert off or on, follow these steps:

  1. Open the Phone app.
  2. Then tap the Menu icon or three vertical dots on the upper-right corner or the screen.
  3. Tap Settings from the given options.
  4. Scroll down to More settings then tap Call Barring from the given options.
  5. Again, disable the feature if necessary then do a test call while it’s off.

If this doesn’t work, then try the next possible solution.

Fourth solution: Switch between network modes.

There are times when the problem is attributed to the selected network mode, which is likely invalid or incorrect. To make sure this isn’t what’s causing your trouble, try to change or switch to a different network mode. Here’s how:

  1. Slide your finger from the top edge of the Home screen.
  2. Tap the Settings icon (wheel-like figure) on the upper-rightmost corner.
  3. Tap Connections.
  4. Scroll to and tap Mobile networks.
  5. Tap Network mode.
  6. Tap to change and select other network mode to use like 4G, 3G, 2G (auto connect).
  7. Press the Home key to go back to the Home screen then do a test call to see if calling functions are already working properly with the current network mode.

Don’t forget to do a test call after switching to individual network mode so you will know if it’s working or not.

Fifth solution: Reset network settings on your Galaxy A7 2018.

If modifying the previous settings doesn’t help, then you may resort to a network settings reset. This will clear your current network settings including erratic configurations or invalid network option selections. Wi-Fi networks and Bluetooth connections will also be deleted in the process. Should you wish to proceed, refer to these steps:

  1. Go to Settings.
  2. Tap General management.
  3. Tap Reset.
  4. Select the option to Reset network settings.
  5. If prompted, enter the password/PIN to unlock your phone screen.
  6. Then tap Reset settings to confirm action.

After the reset, your phone should reboot automatically. If it doesn’t, then you will need to manually trigger your device to restart or soft reset. This is imperative to clear any software glitches and likewise to refresh system functions of your phone. Again, make a test call afterwards to see if the problem is fixed.

You may opt to troubleshoot further if the problem persists. And your next best option would be a factory data reset or master reset on your Galaxy A7 2018. This will wipe everything from your device including bugs and malware. Just be sure to back up all your important data and personal information beforehand because they are also cleared in the process.
