It has been reported that some of those that own the LG V20 have had the camera fail on their smartphones. It seems like this happens after several days of normal usage. The LG V20’s main camera delivers an unexpected message – “Warning: Camera Failed” – and the LG V20 camera stops working. The issue isn’t fixed after rebooting the device or returning it to factory settings.
There isn’t quite a guaranteed way to fix this error, short of replacing the entire phone. The error could be caused by any number of reasons, and you won’t be able to tell at a glance what the cause is. The following are some possible solutions for a camera failed problem on LG V20 that you can do on your own, without getting a retailer involved.
How to Fix LG V20 Camera Failed Problem:
- Restart the LG V20. It isn’t a guarantee, but this could fix the camera failed problem. Hold the “Power” button and the “Home” button at the same time for 7 seconds until the phone turns off and vibrates.
- Go to Settings, open the Application manager and then go to the Camera app. Select on Force Stop, clear data, and clear cache. Many apps don’t completely stop even after you exit out of them, and many have background services running at all times. A Force Stop fully exits out of an app, giving you a chance to fully reboot it without any adverse effects.
- The next attempt is to clear the cache partition.  Again, it’s not a guarantee, but this could fix the camera failed problem on LG V20. Power off the smartphone, then hold and press the Power, Home, and Volume Up buttons at the same time. Let go of all the buttons and wait for the Android system recovery screen to show up. Highlight Wipe Cache Partition using the Volume Down key and press the Power key to select the option.
If none of the methods above work to fix a failed camera on the LG V20, then it’s recommended to get in contact with the retailer or LG and ask for a replacement, as the camera is damaged and not working.
