Why does my phone randomly delete apps?

[Android Central Question]

I've had apps delete themselves, not sure why this is happening. Just happened witih an app called OfferUp which I don't use very often. Its hard to know when it was deleted but I definitely did not delete it myself. I was able to reinstall the app, but this has happened with numerous apps before, not sure if this an Android issue, an LG V20 issue, or what.

Did you move the app to SD Card? If so, maybe the card is failing or got removed at some point, which basically prompts the app to just disappear.
