How To Fix LG V40 ThinQ Freezes When Phone Is Unlocked

Problem:  I am using LG V40 ThinQ. Recently, whenever I unlocked my phone through fingerprint scanning or knock code, my home page then seems to freeze. The only area that is working is the home touch buttons, hence it only start working again when I press the home touch buttons. Do note that the screen is working for me when I am unlocking it as I still can’t swipe open and use knock code. The problem starts (screen freeze) after the phone is unlocked. The video wallpaper in the background is working even though the screen does not sense anything when I touch.

Solution: Before performing any troubleshooting steps on this phone it’s best to make sure that it is running on the latest software version. If an update is available then I suggest that you download and install it first.


Perform a Soft Reset

The first thing you will need to do whenever your phone becomes unresponsive is to do a soft reset. This will refresh your phone software and will usually fix most minor software glitches. The soft reset is done by pressing and holding the Power button and Volume Down until the device powers off, approximately 8 seconds, then release.

Remove the micro SD Card

Does your phone have a micro SD card installed? If it does  then I suggest that you remove it as this can also be a factor that is causing the problem especially if it has some corrupted sectors. Once the card is corrupted the phone will have difficulty in accessing the data stored in it and will usually cause the device to reboot.

Check if the problem occurs in Safe Mode

Sometimes the problem can be caused by an app that you recently downloaded You can check if this is what’s causing the problem by starting the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.

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

If the phone does not freeze in this mode then the problem could be  caused by an app you downloaded. Find out what app this is and uninstall it.

Wipe the cache partition

Your phone will store temporary data in a dedicated partition in its storage space which helps the device run apps smoothly. If this data gets corrupted then issues can occur on the device. To make sure that this is not what’s causing the problem you will have to clear the cache partition of the phone.

  • From the Home screen, tap Settings.
  • Tap the ‘General’ tab.
  • Tap Storage > Internal storage.
  • Wait for menu options to finish calculating.
  • Tap Free up space.
  • Tap Temporary files & raw files.
  • Select the following options: Cached data, Clip tray temporary files, Raw files from camera
  • Tap Delete > DELETE.

Perform a factory reset

One last troubleshooting step you can perform if the above steps fails to fix the problem is a factory reset. Take note that this will erase your phone data so it’s best to backup the phone data before proceeding.

  • Back up data on the internal memory before performing a factory reset.
  • From the Home screen, Settings.
  • Tap the ‘General’ tab.
  • Tap Restart & reset.
  • Tap Factory data reset.
  • If desired, tap the Erase SD card checkbox.
  • Tap RESET PHONE – Delete all – RESET

You can also perform the factory reset using the hardware keys.

  • Backup all data on the internal memory before performing a master reset.
  • Turn off the device.
  • Press and hold the Power and Volume down buttons.
  • When the LG logo appears, quickly release and then re-hold the Power button while continuing to hold the Volume down button.
  • 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.
  • Press the Power button to reset the device

In case the issue still persists even after performing the steps listed above then this could already be caused by  faulty hardware component. The best thing to do right now is to bring the phone to a service center and have it checked.
