How to fix LG G7 ThinQ can’t hear caller issue

There are a number of possible factors that can cause your problem. Follow our suggestions below to fix this problem.

Verify speaker is working. The first thing that you want to do is to confirm whether or not it’s a phone speaker issue. Check if it’s a possible audio issue by recording your voice talking. If your phone no longer makes sound no matter what you do such as when listening to music or playing a game, that’s a clear case of a speaker problem. You must skip all the troubleshooting steps below and go straight to factory reset to know if it’s a software problem.

Check if it’s a contact issue. Does the problem only occur when talking to one contact? If that’s the case, the reason for that is most likely coming from the other end. Tell your contact to troubleshoot on his or her end to figure out the cause.

Forced reboot. Refreshing the system is one of the basic troubleshooting steps to do in this case. If the problem is being caused by a temporary bug, a restart will most probably help. Here’s what you need to do:

Press and hold the Power button and Volume Down button simultaneously for a few seconds and then release both buttons when the phone reboots.

Forced reboot is a good way to simulate the effects of physically disconnecting the battery. If it won’t make a difference, proceed to the rest of the troubleshooting steps below.

Toggle Airplane Mode. Turning Airplane Mode on and off is sometimes effective in fixing network troubles for this device. Make sure to do it if forced reboot has no effect. Here’s how to do it:

  1. Tap Settings from the Home screen.
  2. Tap Network & Internet.
  3. Navigate to the Airplane mode menu then tap the switch to turn the feature on. After about 30 seconds, tap the switch again to turn off Airplane Mode.
  4. Restart the device.
  5. Check for the problem.

Wipe cache partition. Android uses a special cache called system cache to load apps quickly and do certain tasks efficiently. Sometimes, the system cache gets corrupted, causing problems. To ensure that the phone has fresh system cache, you can clear the cache partition with these steps:

  1. Turn the device off.
  2. Press and hold the Power button and the Volume Down button.
  3. Release both buttons when the System Recovery screen appears.
  4. Use the volume buttons to navigate to Wipe Cache.
  5. Select the Power button to confirm Wipe Cache action.

Clear cache of Phone app. In case the problem lies on the cache of the Phone app, the first thing that you can do is delete the Phone app cache and see what happens.

How to clear an app cache:

  1. Open Settings app.
  2. Tap Apps & notifications.
  3. Tap App info.
  4. Tap the appropriate app.
  5. Tap Storage.
  6. Tap Clear cache. This option may not be available for some apps. If there’s no option for you to clear a browser cache, go ahead and clear its data instead.

Clear data of Phone app. If clearing Phone app’s cache won’t help, follow it up by clearing the data. The steps should be similar. Here’s how:

  1. Open Settings app.
  2. Tap Apps & notifications.
  3. Tap App info.
  4. Tap the appropriate app.
  5. Tap Storage.
  6. Tap Clear data. This option may not be available for some apps. If there’s no option for you to clear a browser cache, go ahead and clear its data instead.

Use another Phone app. To further check if the reason for the problem is app-related, you can try using another app when making calls. If you have social media apps like Facebook Messenger, you can use it to see if calling works.

Replicate the issue on Safe Mode. Sometimes, a poorly coded app may interfere with Android and results to problems. To check if one of your apps is to blame, run the phone on safe mode and try to make a call (you can ask someone to call you). If sound is present during this call, that means you have a bad app problem.

To restart to safe mode:

  1. Ensure the device is powered off.
  2. Press and hold the Volume Down button and the Power button until the System recovery screen displays then release both buttons.
  3. Select Safe mode. You can use the Volume buttons to highlight the option and the Power button to select.
  4. The device starts up with ‘Safe mode’ displayed in the lower-left.  This may take up to 1 minute to complete.
  5. Ask someone to call you.
  6. Check for the problem.

If the problem is not present on safe mode, you should use elimination method to identify which of your apps is to blame. Here’s how:

  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. Another important troubleshooting step that you can do in this case is to ensure that you reset all network settings on your device. Doing so will erase cellular and wifi network settings. Here’s how it’s done:

  1. Open Settings app.
  2. Tap System.
  3. Tap Restart & reset.
  4. Tap Network settings reset.
  5. Tap RESET SETTINGS.
  6. Tap Reset Settings.

Check SIM card. Some network problems are caused by SIM card fault. Try to insert another SIM card or use your SIM on another phone. Either way should help you tell if your current SIM is causing the problem or not.

Factory reset. Wiping your phone and returning its software settings to their defaults might look extreme but it’s the last troubleshooting step that you can do in this case.

To factory reset:

  1. Create a backup of your personal data.
  2. Turn off the phone.
  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.

Get help from your carrier. There’s only so much that you can do for this issue. If none of our suggested steps above help, call your carrier and let them troubleshoot the problem. At this stage, you already know that it’s not a device problem so there must another factor outside the phone causing it.
