What it is

Verifies certain upgrade scenarios.

A shim is basically a compatibility layer for an API, that makes sure anything that uses the API does so correctly.

Careful: Disabling could mess with OTA updates.

Commands

adb shell pm uninstall --user 0 com.android.cts.priv.ctsshim

To put it back:

adb shell cmd package install-existing com.android.cts.priv.ctsshim

Every removal listed here is per-user only: the system image is untouched, and the restore command puts the app back from the copy already on the device. Nothing is downloaded.

This is not the directory. Here we say what a package is in general; what happens on your particular television is on your model's entry, and that one wins. The same package can be dead weight on one set and hold the home screen up on another.
