Problem: How to fix LG G7 ThinQ “Phone not working” bug

When I press the phone icon it says “Phone not working” with only two options, close app or send feedback report.

Solution: When it comes to problems with app errors, there’s often no way to know right away where the problem lies. Be sure to follow our suggestions below on how to deal with “Phone not working.”

Restart the app. Forcing a problem app to restart is often an effective solution. Make sure that the Phone app closes and restarts normally. This is to refresh the app and clear any temporary bug that may have developed. Here’s what you can do:

  1. From a Home screen, Open Settings.
  2. Tap Apps & notifications.
  3. Tap App info.
  4. Locate then select the Phone app.
  5. Note If system apps aren’t visible, tap the Menu icon Menu Icon (upper-right) then tap Show system.
  6. Tap Force stop.
  7. Tap OK.

Force reboot the phone. Temporary system bugs may develop if a device is kept running for a long time. If you haven’t tried restarting your LG G7 ThinQ yet, you can simulate the effects of a “battery pull” to refresh the system. This won’t delete any personal data so it can be done safely. Forced reboot is the equivalent of physically removing the battery. While you can’t disconnect the battery from your LG G7 ThinQ, you can simulate its effects by doing a forced reboot. To do that, simply press and hold the Power and Volume down key for 8 seconds. This will force the device to shut down as if the battery has been disconnected, and then turn back on, as if you’ve inserted the battery again.

Check Phone app Permissions. Some apps need extensive permissions in order to work properly. The same is true of all core apps like the stock Phone app. If it’s restricted in some way, it may crash and show the “Phone not working” bug.

To check if your LG G7 gives it the necessary permission, follow the steps below:

  1. Open Settings app.
  2. Tap the ‘General’ tab.
  3. Tap Apps & notifications.
  4. Select Phone app.
  5. Tap Permissions.

Clear Phone app cache. There may be an issue with the app’s cache. To ensure that Phone app is using a fresh cache, try to delete the current one. Here’s how:

  1. From the Home screen, tap Settings.
  2. Tap the ‘General’ tab > Apps & notifications.
  3. Tap App info.
  4. Tap the filter to select the following: All, Enabled, Disabled
  5. Tap the desired app, then Storage.
  6. Tap Clear cache.
  7. Hit YES to confirm.

Reset Phone app to defaults. Clearing of app’s data follows the clearing of the cache if nothing works. By doing this, the Phone app will be, in effect re-installed because it will reverted to its factory state. Be sure to back your contacts and other data ahead to time in order to avoid losing them. If you want, yo can use Google’s servers or cloud to save them.

Once you’ve taken the steps to safeguard your contacts, you can then go ahead and clear the data. Here’s how:

  1. From the Home screen, tap Settings.
  2. Tap the ‘General’ tab > Apps & notifications.
  3. Tap App info.
  4. Tap the filter to select the following: All, Enabled, Disabled
  5. Tap the desired app, then Storage.
  6. Tap Clear data.
  7. Hit YES to confirm.

Check for bad third party app. If the problem started after you installed an app, delete that app and see if it fixes the bug. If you have no idea whether there’s a possibility of a bad app trouble, then go ahead and restart your phone to safe mode.

Here’s how to do that:

  1. With the screen on, press and hold the Power key.
  2. In the options menu that displays, press and hold Power off.
  3. When prompted to restart in Safe Mode, tap OK.
  4. After your device restarts, it displays Safe mode at the bottom of the screen.
  5. Charge the phone.

Remember that no third party app should be able to run while your device is on safe mode. This means that all there’s definitely a problem app should the error stop. To identify the culprit, you must use the good old elimination process. Here’s what you need to do exactly:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your LG G7 ThinQ is still problematic, repeat steps 1-4.

Reset network settings. There may be a network setting or settings that has been modified before this problem started. Try to clear your device’s network settings to see if that will fix the  “Phone not working” error.

  1. Open Settings app.
  2. Tap Restart & reset.
  3. Tap Network settings reset.
  5. Tap Reset Settings.
  6. Check for the problem.

Reseat SIM. In some similar cases in the past, temporarily disconnecting the SIM card helps in fixing network and Phone app errors. Be sure to try it on your case and see if works.

To prevent corrupting data, be sure to power down your phone before removing the card. Do the same before inserting it.

Clear cache partition. Sometimes, a corrupted system cache can cause problems. Android uses a set of temporary files to load apps faster called system cache. If this cache becomes outdated or corrupted, the phone may encounter performance problem, app crashes, and other sorts of problems. To see if a corrupted system cache is to blame, follow the steps below to clear the cache partition.

  1. From the Home screen, tap Settings.
  2. Tap the ‘General’ tab.
  3. Tap Storage > Internal storage.
  4. Wait for menu options to finish calculating.
  5. Tap Free up space.
  6. Tap Temporary files & raw files.
  7. Select the following options:
  8. Cached data
  9. Clip tray temporary files
  10. Raw files from camera
  11. Tap Delete > DELETE.

Install updates. Making sure that the software on your device is up-to-date is one of the ways to lessen the chances of bugs from developing. While there’s no guarantee that it will fix the issue you’re having, it still is highly recommended whether or not you have an issue.

Factory reset. Factory reset is a drastic solution in this case but it may be the only effective way to fix the problem at this stage. Make sure to create a backup of your files or data before doing it.

  1. Back up all data on the internal memory before performing a master reset.
  2. Turn off the device.
  3. Press and hold the Power and Volume down buttons.
  4. When the LG logo appears, quickly release and then re-hold the Power button while continuing to hold the Volume down button.
  5. When the ‘Delete all user data (including LG and carrier apps) and reset all settings’ message appears, use the Volume down button to highlight Yes.
  6. Press the Power button to reset the device
