Connectivity Engine that runs in the background as part of the System.
Enables seamless hand-off between mobile data and Wi-Fi networks. Can also dynamically measure network performance to prioritize using the best one (I think that’s part of “Intelligently select the best Wi-Fi” in settings).
Probably worth keeping on; I noticed connection reliability getting worse when I disabled it.
