How to troubleshoot LG G7 ThinQ with screen flickering issue

I would assume that the screen flickering hasn’t been happening out of the box because if your device is already like that since day 1, this isn’t the place where you should be. You should already go back to the store and have it replaced since it’s a hardware or a manufacturing defect. However, if the problem started out of nowhere with no apparent reason or cause, then here’s what you should do…

First solution: Reboot your phone

This method is for those who encountered the problem for the first time and haven’t rebooted their phones yet. It’s possible that the flickering is due to an app you’re using and a restart may be able to fix it. Better yet, try doing the forced restart by pressing and holding both the volume down and power keys at the same time for 8 seconds or until the device boots up. If the flicking continues after doing this, then you have to do the next procedure.

Second solution: Run your LG G7 ThinQ in safe mode

This method will make your device run with all downloaded apps temporarily disabled. It will tell us if the problem is caused by a third-party app or not. So, follow these steps to run your phone in safe mode:

  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.

Continue using your phone while in this mode to know if the flickering still happens. Assuming the issue is fixed, find out which app causes the problem and uninstall it. Here’s how you do that:

  1. From the Home screen, tap Settings.
  2. Tap theGeneral’ tab > Apps & notifications.
  3. Tap the filter to select the following:
    • All
    • Enabled
    • Disabled
  4. Tap the desired app.
  5. Tap Uninstall, then tap OK.

On the other hand, if the flickering continues even in safe mode, then we need to rule out the possibility that it’s just a firmware issue. Try the next methods.

Third solution: Wipe cache partition

This will rule out the possibility that this problem is caused by some corrupt system caches. Don’t worry, you won’t lose your files and data if you did this. All the system caches, however, will be deleted and replaced with ones that it all happens automatically. What you need to do on your end is initiate the process. Here’s how you do that:

  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:
    • Cached data
    • Clip tray temporary files
    • Raw files from camera
  8. Tap Delete > DELETE.

If the problem continues after this, then you have to do the last procedure.

Fourth solution: Master Reset

This is your last resort and if the problem continues after this, then it’s time you brought it back to the store and have it replaced. Before that, make sure you backup all your important files and data especially those that are stored in your phone’s internal storage as they will be deleted. After which, follow these steps to reset your phone:

  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.

After doing all the procedures above and the screen flickering continues, then have a technician take care of it.
