Media and devices

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

What it is

Kind of a hub for managing the media played on smart devices (e.g play music to 2 Bluetooth devices simultaneously with Dual audio).

Has a lot of permissions and asks for ACCESS_COARSE_LOCATION, QUERY_ALL_PACKAGES.

Careful: Removing this package does not prevent you to connect your phones to smart devices, but oddly enough causes the brightness slider in the notification panel to not be displayed in landscape orientation (it's still shown in portrait) on some devices.

Commands

adb shell pm uninstall --user 0 com.samsung.android.mdx.quickboard

To put it back:

adb shell cmd package install-existing com.samsung.android.mdx.quickboard

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.
