What it is

UCE shim service

UCE = User Capability Exchange. A shim is basically a compatibility layer for an API, that makes sure anything that uses the API does so correctly.

Used for RCS. Provides a discovery service for users to see the capabilities of other users.

UCE is based on SIP PUBLISH and SIP SUBSCRIBE/NOTIFY.

Devices PUBLISH their capabilities to a presence server, when another device wants to find out what the other party supports, the device sends a SUBSCRIBE to the presence server which then returns a NOTIFY of what the other party supports.

Commands

adb shell pm uninstall --user 0 com.qualcomm.qti.uceshimservice

To put it back:

adb shell cmd package install-existing com.qualcomm.qti.uceshimservice

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.
