What it is

Face service detection

Analyzes all the photos in the Samsung Gallery to detect human faces using Samsung’s built-in face detection technology. Once FaceService identifies that the photo contains a face, it shows a button that allows users to add name tags to the photo and create a People Album of similar photos by selecting the name tag.

Same shared user id as com.samsung.ipservice, com.samsung.mlp, com.samsung.cmh

Needed for face recognition in the Gallery

NOTE : Removing this package does not break face unlock

Commands

adb shell pm uninstall --user 0 com.samsung.faceservice

To put it back:

adb shell cmd package install-existing com.samsung.faceservice

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.
