How to troubleshoot LG V35 ThinQ with screen flickering issue

The following are the procedures you have to take to know why this is happening to your new phone. Hopefully this problem is just a firmware issue so that it could be fixed by one of the procedures below…

First solution: Reboot your phone

If you haven’t done it and if this is the first time you’re having this problem, then you should restart your device first as it could be just a result of a minor glitch in the firmware. I’ve encountered similar issues in the past that were fixed by a mere reboot. If the problem continues after the reboot, then 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 reboots. If the it continues to bug you after this, then move on to the next solution.

Second solution: Run your V35 ThinQ in Safe Mode

You should know that running the device in safe mode doesn’t really fix the problem but it will give you an idea if this issue is caused by one or some of the apps you installed. When in this mode, all third party applications are temporarily disabled so if the problem doesn’t occur, then it’s clear that one or some of the apps you installed is causing the flickering. Find out which app it is and uninstall it.

Here’s how you run you LG V35 ThinQ 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.

And this is how you uninstall an app from it…

  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 still occurs even in safe mode, then try the next procedure.

Third solution: Wipe cache partition

You need to do this because there’s a possibility that the problem is caused by some corrupt system cache. Don’t worry, none of your files and settings will be deleted or changed if you did this but it’s very effective:

  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 flickering continues to occur after this, then you have no other choice but to do the next procedure.

Fourth solution: Perform the Master Reset

Now, this is your last resort and it will rule out the possibility that this problem is with the firmware. After doing this and the problem continues, then you have to bring the phone back to the store and have it replaced because it’s clear the problem is with the hardware. Before the reset, make sure you backup all your important files and data as they will be deleted.

  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.
