What if I want privacy on a non-home network? Huge part of my traffic is over 5G/LTE.
Nextdns have their own app for this as well.
For android 9 or higher there should be an option in network settings.
Though you need a trusted host to act as the other end, or you are just swapping one monitored link with another, and finding that could be a task in its own right depending on your threat model / paranoia level.
