What it is

Finds and auto-connects to available hotspots to minimize cellular data consumption.

Auto-connects is not a good idea. You are ok if you go on HTTPS websites. Use a VPN if you want to hide the domain names you visit, avoid usage restriction (no P2P, blacklisted websites...) and encrypt HTTP traffic.

Commands

adb shell pm uninstall --user 0 com.att.android.attsmartwifi

To put it back:

adb shell cmd package install-existing com.att.android.attsmartwifi

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.
