I've been using NetGuard for a little while now, and I've really liked it so far. I hate the forced system updates which seem to come more and more frequently. For a handful of reasons, I'd like to prevent this from happening via NetGuard, if possible. I have to imagine there's a service or two which compares my Android version with the latest available version, and perhaps another which actually downloads the latest version. The problem is that the list of apps and services to restrict are vast, and I have no idea what most of them do. What on this list needs to be restricted in order to prevent all future forced updates?
