How To Fix LG V40 ThinQ Randomly Turns Off
Problem: My V40 ThinQ suddenly started having weird issues. It’s not been dropped, wet and doesn’t get hot. I haven’t added any new apps recently and have relatively few. Fb, mewe,ebay, amazon, square. Plus several shortcuts added to home screens. It shuts off suddenly. I have to do a soft reset battery to get it to restart. But I have to do this 3 or 4 times. I wait at least a minute before restarting the phone, it sticks on either “LG” or att logo. Finally it works. Other issues, if not shutting off, is screen locking up or unresponsive. I checked my voicemails today and pressing numbers to delete or save wouldn’t respond. Swiping home screen pgs it got stuck halfway in between and screen was slightly blurry. Had to do a restart. I’d hate to do a factory reset, my phone has all passwords, photo albums set up, tons of stuff I’d hate to lose or have to spend hrs reorganizing. The battery charges fairly quick and holds a pretty good charge unless I’m on it non stop. Haven’t noticed any battery issues. This is also an insurance phone, I’ve not had the best of luck with the refurb phones in the past. Thanks for any help. I also download a known virus detector and found no issues. Caches, history etc always cleared also. Any thoughts? Time to upgrade? I just like this phone and screen size for business and Internet searches. Also have no idea what operating system it is on. Thanks again.
Solution: Before performing any troubleshooting steps on this phone it’s best to make sure that it is running on the latest software version first. If an update is available then you should download and install it first.
The first thing we will be doing is to check if the problem is caused by a software glitch. Follow the troubleshooting steps listed below which are recommended for this particular issue.
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 phone turning off on its own. 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.
Try to check if the issue occurs in this mode. If it doesn’t then it could be caused by a downloaded app. Find out what app this is and uninstall it.
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.
Check if the issue still occurs.
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
Do not install any apps first after the reset. Try to check first if the phone will turn off.
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 as this could already be caused by a faulty hardware component.
