I have tested Adhell, AdLock, Blokada, Adaway, DNS66 plus a couple of others. But, Adguard works flawlessly irrespective "Free or Pro."
Yes, adguard works absolutely fine, even in "free" version, no ads anywhere, in my days with the note 8, some ads showed, very few, but now, with my note10+, I cant even recall seeing a single one

How can you have adhell working?

For the record, adhell (adhell3, source for 3.2.314 still available on GitHub) never quit working! What happened is that Samsung finally patched a "hole" in previous Knox implementations. Currently, you need a legitimate partner-issued key for adhell to work. No, there are no workarounds, no you can't pretend to be a Samsung partner, and no partner will share his/her valid keys with you... ;) As previously discussed in the old adhell threads, there are quite a few simple and free alternatives, most a lot simpler than what I see discussed in this thread.

It does not.

It uses the firewall provided by Knox to block outbound connections.

Or works more like a host file adblocker, like adaway, but without DNS requests made since the blocking is done by your phone.

What still had a to be figured out, is to know if it doesn't take more battery instead, since apps may not be aware the requests are blocked so they may try hard and continuously try to connect blocked addresses.

You can use Android's Private DNS for system wide ads and browser extension for placeholders ; only Firefox mobile supports them as far as I know.

Your best bet is to set up PiHole at home on a Raspberry Pi (or on a server in Ubuntu on a VM, etc), and install OpenVPN on that server too. Install OpenVPN on your phone and when you are not home on your own WiFi network, enable the VPN on your phone and all ads, placeholders, etc are blocked and gone. Been using this for over a year.

PiHole is easy to set up. I have all my devices running through it.

    block ad without any software

    I'm a developer myself and a tech enthusiast, and I don't mind spending $$$s on things I like.

    My reviews are based on four factors.
    1. Strength of adblocking,
    2. Security
    3. Price
    4. Ease of disabling adblocking.

    The reason why I need to disable adblocking from time to time is because of some redirection links don't play well with adblocking. And some other situations where I need to click on an ad.

    1. Adguard Pro: In my opinion, the paid version of adguard does the best adblocking via the VPN it creates. It also works with socks5 proxy if you want to use a secondary vpn like PIA. This is exactly my preferred setup, I paid for a lifetime subscription for this for $12 for 2 mobile and 2 computer license. Yes, I did get a good deal at that point. It is also very easy on battery and I highly recommend this if $$$s are not a problem.

    1. Strength of adblocking: Perfect (can add custom lists if more blocking is needed)
    2. Security: adblocking is done locally on your phone so highly secure. Your request URLs and data isn't going out to a remote dns server.
    3. Price: expensive
    4. Ease of disabling adblocking: easy, just from a dropdown in notifications.

    Now let's come to adguard DNS or pihole as a DNS server option. Adguard DNS blocks all ads for me. You can use it either directly by entering it in the settings (I dont like this option though because if you temporarily want to disable adblocking, its pain in the butt.) I like using the DNS servers using a simulated VPN app for DNS changers. There are quite a few available on play store. My favorite one is :

    Adguard DNS via DNS changer:

    1. Strength of adblocking: high, but not customizable, whatever they offer as blocking you gotta live with it. However, note that they are pretty good with blocking ads. I never felt any problem.
    2. Security: all requests go out to a remote DNS server, which either allows the request or blocks it. So not secure at all.
    3. Price: free
    4. Ease of disabling adblocking: easy with a DNS changer software.

    PiHole via DNS changer:

    1. Strength of adblocking: High, you get super high control over ad blocking.
    2. Security: The DNS server is at your home so its secure. Your data won't go out to any other company.
    3. Price: Needs an always on server running at home. People usually get a raspberry pi for this. If you need adblocking outside of your home, you'll also need a dynamic DNS service or a static IP address, which can be expensive. But you get what you pay for. You can do a lot more with this setup if you are a tech enthusiast like me.
    4. Ease of setting it up and disabling adblocking: You need to be technically fairly comfortable with linux to set it up. There are some simple scripts and guides online though. Disabling is easy though.
    I use Private DNS (Settings -> More connection settings -> Private DNS) and does a pretty good job.
    You tube Vanced is also helpful to get rid of youtube ads.
    I wish adhell would come back!

    If you don't mind a little de-compiling of another app that has a working KNOX key and hacking that together with the Adhell still can :highfive:
    I got app from Note 8 days called Disconnect Pro from Samsung Store and it works with KNOX so its system level ad blocking and it works fine with Note 10+
