com.android.phone.injection

Risk: Safe
Source: Manufacturer
What it is: System core

What it is

Possibly safe, or useless as removal doesn't seem to change anything.

It's a very small APK, it's a single class which only assigns a constant numeric value to a variable called 'telephony_injection'

Commands

adb shell pm uninstall --user 0 com.android.phone.injection

To put it back:

adb shell cmd package install-existing com.android.phone.injection

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.
