Risk: With care
Source: Manufacturer
What it is: System core

What it is

It's not only security but it has a lot of useful settings.

Better keep this.

Commands

adb shell pm uninstall --user 0 cn.nubia.security2

To put it back:

adb shell cmd package install-existing cn.nubia.security2

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.
