System-wide Android ad blockers
Apparently, in Android there are a number of systems to block ads inside Android apps; see e.g. https://forum.xda-developers.com/android/general/guide-ad-blocking-t3218167 . Some of them require root, some don't; from what I understand, they mostly work with by altering the DNS.
Has anyone tried blocking Android ads inside Jolla phones? I suppose these methods won't work inside Aliendalvik, since they play heavily with the Anroid network stack?
