All the people suggesting firefox...

Pihole for network wide ad blocking (no ads on all apps on all devices within the LAN) then self-host a vpn to keep your phone within that lan.

Tis what I do at least.

Blocks pretty much everything except Youtube, and Twitchs video ads as they serve their own ads from their own domain's as well as things like sponsored posts on reddit/twitter/facebook.

Don't watch much Twitch, Youtube (re)Vanced is a thing, and Twitter/FB/Reddit can all die in a fire. So none of those are issues for me either.

i dont mean be that guy, but opera is chinese spyware, and firefox is worth the switch. trust me, i used to love opera, but now using firefox (librewolf/mull), i could never go back

Wait since when is firefox considered slow ? For me the speed is decent i dont have a 1000$ phone so i dont expect it to be as fast as on my pc

Why not change your system DNS to the public AdGuard address? Then you don't need to use the app. DNS filtering is still more limited than uBlock, of course, but if you refuse to use browsers where that's available, I think that's the next best option.

Firefox + unlock Origin. Use alternative opens-source apps. DNS: Adguard, NextDNS, etc.

Firefox with uBlock Origin is by far the best option, the only other browser that comes close is Brave, their content blocking and such is pretty good, so I'd recommend trying them if you're hellbent on not using FF. I'd also recommend looking into NextDNS for system-wide ad/tracker blocking in conjuction with the browser.

Easiest solution I found was manually setting a Private DNS on Android. Adguard public DNS address filters pretty much all of them.

https://controld.com/free-dns has free DNS resolvers that do the same thing as a pihole. you just go to your phones "Private DNS" setting and at it there. this will work for non-browser apps as well!

Firefox on Android allows a few extensions. A few of those are privacy badger, ublock origin, and decentraleyes. Should meet your need at a base level.

EDIT: Spelling

Firefox + uBlock origin, and reVanced for YouTube ad-blocking/other features.

NextDNS

Firefox and Kiwi browsers both support full Ublock Origin

You can try out nextDNS. It has a list of blockers and you can track and block what request are being made by your phone.

Additionally, DNS-crypt proxy can be a good alternative too.

In your case I'd sacrifice a bit of speed and went with Firefox. Another option is AdGuard + AdGuard VPN, the apps can work together.

1. Create a free Nextdns account.
2. Add some blocklists
3. Use the private dns settings on your android to set the dns. (i think this feature is present in Android versions which are 9 and above)

Voila ! you have blocked ads without wasting your VPN slot.

As an added bonus you can also configure nextdns to block your specific phone vendor tracking as well.

If you are interested in trying different web browsers you can check out Fennec from F-droid or Brave browser. These are my go-to browsers on android.

You wouldn't be able to use AdGuard properly with Opera anyway because Opera don't accept user certificates (issued by AdGuard or AdAway) so it wouldn't filter https traffic.

Try Vivaldi, amazing browser, built-in adblocker. Hopefully will be better than Opera's. Personally haven't tested it as I'm using said AdGuard which Vivaldi has no problem with - one of the reason I moved from Opera to Vivaldi.

Or simply change DNS to AdGuard.

Kiwi Browser is Chromium based and supports desktop add-ons like uBlock Origin.

Have you heard about pihole for DNS blocking ? You m might have success when at home on wifi as this would greatly cut down on ads and trackers.

Otherwise, if you think Firefox is too slow to pirate (not sure I understand that, but ok) you can try another browser .. maybe try Brave? Ya, maybe some negative publicity lately, but I'm not sure it bothers me, or perhaps I don't understand what exactly they might be selling of my info..

Mullvad vpn has an ad blocking feature Although ive never tried it

Blokada.

If I were you I'd just root my phone and use it along with AdAway.

If that isn't an option for you you already got some neat answers like using a public DNS or your own self hosted.

If you don't mind paying, Blokada has a "cloud" subscription. You set your DNS settings on the phone to what they give you, turn it on in the app once, then it runs without using the VPN method.

I use it because, even though it's another God damn subscription, it seems to work better for me and now I don't have to think about it.

RethinkDNS and Firefox+Ublock-Origin

I'm in a restricted country and my phone is not rooted, so if I use ad block apps like AdAway or Adgaurd they need to create a VPN connection in order to function unless the phone is rooted, and that VPN connection doesn't let me to enable another VPN in order to visit filtered websites or apps.

Ultimately, I think rooting is the way to go, but only if you have a device with a decent XDA thread guide and support. If you choose not to root, Adguard has their own VPN service integrated if you wanted to pay for that (haven't tried), or else you can add your own proxy servers through the app – so you can add individual server IPs for (say) Nord and connect to them while still using Adguard in VPN mode.

I find configuring an ad blocking private dns over https DOH in Firefox much faster and efficient compared to other methods. Firefox Extensions and VPN add unnecessary over head.

If interested, the steps are documented in my notes - https://abskmj.github.io/notes/posts/android/firefox-dns-https/

I used to be a big fan of Opera back when it was good but I wouldn't recommend using anything made by them since they got bought out by a shady Chinese company that makes their money off of predatory payday loan apps with exploitative interest rates in a few developing nations. Firefox (and Mull and the like) are the best Android web browsers but if you really want a Chromium-based one then I'd recommend looking into using one that's open source and not owned by an unethical corporation.
