How To Fix LG V40 ThinQ Randomly Restarting

Problem: I have had  strange issue with my V40 ThinQ  lately that i can’t seem to find a solution or cause for. it works fine for either a hours however randomly in use it will shut down and restart, once this happens it doesn’t stop and will keep starting up and restarting never lasting more than a minute before rebooting meaning i have to go the day without a phone till i can get home and charge it. While this is happening the battery drains very fast and the only way i have had to get it to stop is to leave it on charge for hours, usually overnight  (it keeps rebooting while charging) sometimes after this it will be fine other times even after charging to full it will do it again, what i find strange though is when it works it works fine and can do so for a day before it happens again. when it starts the rebooting it does it in safe mode, clearing the cache does nothing and even a factory reset doesn’t work, i have also let the battery drain fully then recharged and it still occurs. i have of course tried different chargers plugs and even wireless and non fast charge as well. if the phone is turned off when this is happening it does turn itself back on only to continue rebooting. The hardest part of trying to find a solution has been a lack of any error messages and the device maintenance  say there are no problems and every time i think it’s sorted it will happen again.

Solution: One of the main reasons why a phone will randomly restart is due to a software glitch. To check if this is the cae you will have to proceed with the troubleshooting steps listed below.

Remove the microSD card of the phone

If you have a microSD card that has corrupted sectors then it could cause certain issues on the phone including and not limited to the restarting problem. Try removing this card then check if the issue still occurs.

Start the phone in Safe Mode

To check if an app you downloaded is causing the problem you should start the phone in Safe Mode. When the phone operates in this mode only the pre-installed apps are allowed to run.

  • Turn off the phone.
  • 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.

Wipe the cache partition of the phone from the recovery mode

Clearing the cache partition of the phone will erase the temporary system data which if corrupted can cause this problem.

  • 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.

Backup your phone data then do a factory reset

One last troubleshooting step to consider is a factory reset. Make sure to backup your phone data before proceeding with this step.

  • 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

In case the issue still persists even after performing the steps listed above then you should bring the phone to a service center and have it checked. You should also consider claiming the warranty on this phone and having it replaced with a new one.
