[AC Question]

The "smart clean" is dumb! How do I turn it off? How do I get a list of my deleted apps?

Welcome to Android Central! Which phone do you have?

Getting a list of apps that are no longer on the phone is like telling you to turn left where the red barn used to be. If they're not on the phone, there's no way to get a list of them.

Most "smart cleaner" apps, though, just remove apps from RAM, not from storage. You can still run them again. (And removing them from RAM is wasteful - this is Android, not Windows. Windows wants free RAM, Android wants as much RAM in use as possible. Unused RAM is wasted RAM in Android.)

If you have an LG G3, and you are using this: LG G3: Release Dates, Specs & Latest News | LG USA
it will only get rid of the apps you downloaded. In which case, you can view them in your Play app. Click the menu at the upper left, go to my Apps, swipe over one pane will show your download history.

Never thought of the "subtractive method" (anything on the list and not in the phone was deleted).
