What it is

Wifi Hotspot service

REMINDER : Hotspot enable you to share the phone’s 4G data connection with any Wi-Fi capable devices.

It is not the Hotspot feature. Only the widget !

Dual SIM status widget

Probably only present in dual sim LG phone variants. Does not remove the persistent notification or dual SIM functionality.

Service menus. I believe if you remove the last one the secret code you can dial doesn't work anymore (who needs it anyway..?)

LG support App remote access

You probably don't want that to happen

LAOP test [MORE INFO NEEDED]

I don't know what LAOP is. I could not find information about it. It's a test so it's probably fine. I have removed it.

Commands

adb shell pm uninstall --user 0 com.lge.lgfmservice

To put it back:

adb shell cmd package install-existing com.lge.lgfmservice

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.
