How to fix LG G7 ThinQ texting issue (randomly shows failed message bug)

Today’s post will address another texting problem for the LG G7 ThinQ. The issue is about a device randomly showing a message suggesting that a text message failed to send. If you have a similar situation on your LG G7 ThinQ, find out the troubleshooting steps that you can try.

Problem: LG G7 ThinQ randomly shows failed message bug

I’m using Messages on my LG G7 ThinQ. I get the failed message symbol on a pic message that is a few weeks old. Like I’ve been texting my wife for those weeks, never an issue, and I know she got the pic cuz she posts them on facebook. All.of a sudden the notification shows next to her message thread. I hate it, so I scroll to see what message didn’t send to delete it or resend it, to remove the notification, and it is always a quite old pic. It happens at random and to my knowledge, unrelated to installing updates, as I definitely don’t update as frequently as it seems to happen.

Solution: This problem can be difficult to fix as there’s no direct way to know where the problem lies. You should do a set of troubleshooting steps in order to narrow down possible causes.

Forced reboot

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.

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 If this cache becomes outdated or corrupted, the phone may encounter performance problem, app crashes, and other sorts of problems.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.

Clear app cache

In case a bug has develop within the messaging app’s cache being used, you can try clear it by refreshing it. Here’s how to clear an app cache:

  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.

Delete old conversation

Text messaging problems are sometimes caused by old conversations. Try to delete the conversation thread that keeps showing the random failed message error and see what happens. If possible, try to also delete other threads to make space for more incoming and outgoing messages. If you are fond of sending MMS or messaging that have attachments, the messaging app’s storage can fill up easily.

Delete app data

Another way of directly dealing with the app in question is by clearing its data. This will return all its settings to its factory state and erase all messages. If you want to save your texts, be sure to back them up ahead of time.

To clear an app’s data:

  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.

Reset network settings

There may be a network setting or settings that has been modified before this problem started. To ensure that your LG G7 ThinQ has all the right network configuration, we suggest that you do the following:

  1. Open Settings app.
  2. Tap Restart & reset.
  3. Tap Network settings reset.
  5. Tap Reset Settings.

Reseat SIM

Some users were able to fix certain network issues by removing the SIM card temporarily. Make sure to turn the phone off before you remove the SIM. Do the same thing before you insert it back. Be sure to restart the phone once you’ve remove the card.

Use another messaging app

If the problem stays at this stage and does not appear to be going away soon, the next good thing to do is to use another messaging app. There may be a coding bug in the app that can’t be fixed by doing the steps you’ve tried so far. There are many free messaging apps that you can use in Google Play Store. We suggest that you stick with the reliable ones like Google’s own Android Messages app.

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

Contact your network operator

Text messaging problems are sometimes caused by issues outside a device. If nothing has worked so far, make sure to let your network operator know about the issue so they can help you troubleshoot it.
