I saw there was a thread about ad blocking on android but I was wondering the best methods for ad blocking that cover the entire phone if possible like in app ads and such as well.
It’s DNS based ad blocking, isn’t it? If so, it doesn’t help with all kinds of ads.
Yes, because their ads are served on the same server (googlevideo.com iirc) as the actual videos. Blocking that domain would block the videos too.
You can’t do better than that on iOS. But the PiHole still goes a long way. It made web browsing from my phone tolerable when combined with the content blockers from Firefox Focus.
Safari content blockers don’t cover the entire phone like the OP was asking about.
