thanks for your work, the permission tab has no longer support after API level 30, (as Knox docs sad). Maybe adb debug permission can be used instead of this deprecated API, although this permission needs to be reactivated after every reboot, like rikka.appops.

Hello, it is working fine in my galaxy 22 ultra. Thank you for sharing. How can I increase the domain rules to a higher number? I know that it sounds unnecessary but I would like to test a higher number. Thanks again.

Decompile and modify the “.line 42”，in the .apk/class.dex/com/fusionjack/adhell3/tasks/DomainRxTaskFactory/，the hexadecimal number “0xc350” limited to 50 000，modify the next line code “if-le v1, :cond_4b” to “if-gez v1, :cond_4b”， After modification, there is no limit.

I got mine to work. With NotifyRDS after I had a grey screen with EMM with leaving take media out checked.
Here are my complete steps that I did which finally worked.

1. Install NotifyRDS app.
2. Launch Notify and enable admin as requested and get Knox key (all three green).
3. from resents clear it
4. enable secure folder from settings, you need some security, I did pattern.
5. add NotifyRDS to secure folder and launch from and fully enable and get Knox key as before.
6. clear it from resents again
7. Remove admin app and uninstall NotifyRDS from normal system
8. open secure folder and try to remove NotifyRDS (fails, blocked by security policy even with admin removed)
9. in secure folder hit three dots, settings/more/uninstall, UNCHECK the default "take media out of secure folder". (I think this was the key for me.)
10. Install adhell from #686 above.
11. without opening it, enable it in device admin apps
12. Loaded without issue.

My favorite use of Adhell is the ability to disable services and receivers without disabling an app. So Google Play Services and Samsung apps can be limited without the issues disabling might cause. Such as not start at boot.

Does anybody have safe services , receivers, activities list that you can share with the rest of us?

Thank you. I'm going to stick with the default list and block chrome and edge. So far it has been working well.

Could anyone tell me what is different between adhell3 vs other adblock solution (like DoH, DoT, or adblock VPN app), in term of blocking ad.
Thank you.

AdHell uses Android's firewall to block outgoing requests to ad servers without using a VPN.

To be able to block ads without AdHell, you have to use a VPN apps that is made to let you customize network rules. Using a VPN uses différent network rules than Android's without it, as all network requests go through there to be secured before being set on the Internet.

DoH, Dot and such are a different things. It's only about encrypting DNS requests. You can now do that with a recent Android with its Private DNS setting.

Still, a VPN app can you let you customize rules more thoroughly, like not only filtering DNS request.

(I'm not an expert so feel free to correct me if I'm wrong)

Still not clear enough for me.

So adhell3 just modifies Android firewall, and blocking ads is Android firewall's responsibility.
Ads block VPN is different since it blocks ads by itself.

Am I right?

The VPN has its own network configuration and all traffic is routed there so it also may have its own "firewall" rules. I don't know how much it is limited in comparison of Android's one.
Routing all traffic through VPN is said to be more battery intensive but I wonder if it's still the case now.

AdHell got an advantage over VPN back in the day because you can use both at the same time, where you can use only one VPN at a time. I don't have any use but it may be useful for others.
I may have lose it because I don't know if the Android's firewall works if a VPN is set up nowadays

It could be better to use AdHell for anything but the adblocking feature, since it can't do cosmetic blocking like AdGuard.

Recently adhell3 is not blocking on chrome. Didn't change any rules, still have port 53 blocked.

Not working at all anymore. I will try the install process again.

    I activated the license in some of my own combined ways, I guess that is the method that currently works, but no one from here sent me a tutorial because none available on the internet works on android 13. I managed to combine some things and activate adhell

    Sorry , somehow your pm was overlooked, it was too short and incomprehensible so I forgot about that somehow. Good news is you find your own method.

    Very unfortunate about samsungs policy changes indeed, tried getting a partner account but was rejected... Might give it another try with some extended information (now as the bare basics, hoped it would be a semi-automatic thing but seems they actually properly check).

    Using Adguard premium in the meantime, but adhell would be my preferred choice. Unfortunately no valid license anymore so too bad...

    Let's try a quick reality check about basic blocking of ads and tracking servers on unlocked Samsung phones. A lot depends on your actual needs and mostly paranoia level, but it's a lot easier than often assumed.

    - If you have a functional adhell, do nothing and keep using it. Nobody can predict the future, but when your key expires, you'll have other options. Just relax and have a pleasant day.

    - No adhell but you're on Pie? Set your Private DNS to "dns.adguard.com". Just relax and have a pleasant day.

    - No adhell and still on Nougat or Oreo? Grab Intra and set the DNS to "https://dns.adguard.com/dns-query". Just relax and have a pleasant day.

    - Want more control over what you block? Use a VPN such as VPN Hosts which supports wildcards and local hosts file. Just relax and have a pleasant day.

    - Don't like any of those? Grab any DNS server or VPN that strikes your fancy but please use your own judgement about what actually works for you, not what someone online somewhere (myself included) says you should do.

    Those are not formal recommendations or endorsements of any specific product or approach, merely a realistic assessment of simple alternatives with a minimal amount of confusing technobabble.

    For most users, any of the above options will be more than sufficient and chances are you won't notice any actual difference in battery use or speed. Try them for yourself, it's easy! ;)

    I manage to find a new way to run adhell on android 13, confirm working on my s23U. But it is the only method so i cant share publicly for the sake of keeping Adhell safe. PM me if you want to know the way, ill reply if i had time

    Edit: after Auguste 2023 update , some user feedback that this method won't work anymore. So I guess that's it for us. For those that got work, it still work good

    Adhell 3.1.x – KNOX AdBlocker for Samsung Galaxy devices and Package Disabler
    . Adhell is a Samsung Knox based application which can Block system-wide Ads, trackers, analytics from applications without root. It has more functionalities than just Ad-Blocker including Package Disabler, Mobile Restricter, App Permissions controller

    Z6PkxmJm.jpg


    Features
    • Pre-Activated KNOX ELM Licence (Must be renewed every 3 months, and can be generated from url below)
    • Domain Limit Size Increase (50,000)
    • Disable Apps Enabled by default
    • Apps Component Enabled by default
    ADHell v3.1.1 - Download
    The APK provided my cease to function at any time, due to the restrictions put in place by Samsung Knox key validation and not due to the fault of my own doing.
    I hold zero responsibility for the use of this app in any liable circumstance.
    *Unknown Apps must be enabled to install third-party APK files.

    If you don't wish to use the above download you may compile your own APK from the source below




    WHAT TO DO WHEN IT DOES NOT ACTIVATE/BYOA (Build Your Own App)
    Error: 102
    This appears due to the Licence being activated more than six times with the same package name while using a developer ELM key and not a commercial partner unlimited use ELM key (Samsung KNOX restriction not the App)
    You have a couple of options -
    • Change the ELM Key pre-installed by opening the app and going to the settings menu of the Adhell3 then scroll to the bottom of the menu and you will find the button to change the key to your own Knox ELM you generated.
    • Use an APK editor to make a change to the installed package name so that it is unique which should allow the pre-installed key to activate (ask others how to do that, but this might bypass the six activation limit under the same package name)
    • Compile your own version of Adhell3, instructions to do so are below.
    Please note as of this time if you don't already have a Knox ELM key generated from some previous use of Knox API applications you will have to wait as ELM key generations have been removed from SEAP for non-partner developers until further notice.

    How to compile your own version of Adhell3
    1. First grab the KNOX SDK and LIB you want the Knox SDK 3.3 (API level 28) & supportlib.jar (Dec 17/18, for older devices)
    2. Get yourself a new KNOX ELM Key from here, It should look something like this.
    3. Grab the Adhell3 Scripts from here, and follow the instructions which are clearly written for your operating system. (Note: you may need to type
      Code: 
      adhell3.cmd setup
      under windows 10)
    4. When you are done you should be left with a folder looking like this which has your built APK package file ready to be moved to your device for install.
      If you struggle to understand how to modify the app before compile I have a ready to go app.properties you can use as a base, just be sure to place the file where the instructions say and to add your OWN KEY in the
      Code: 
      skl.key=yourkeyhere

      An example app.properties file could look like this -
      Code: 
      package.name=com.adhell3.12345
domain.limit=100000
enable.disableApps=true
enable.appComponent=true
appComponent.showSytemApps=false
skl.key=D39335379587987309734637654687675985678078960879789057y58659867967890876706780670

    Folks, I see LOTS of misinformation in this thread. I strongly suggest that you look at the "official" AdHell3 GitLab repo and associated discordapp support area. At the very least, check the README on GItLab.

    Compiling: AdHell's current dev has provided convenient scripts for Windows/MacOS/Linux that make creating/updating your own copy a trivial matter. You can also use Android Studio or git, but the scripts are probably by far the easiest approach for most casual users.

    Using precompiled APKs: Your only choice if you don't have access to a computer, but tread very carefully. You MUST change the package ID (with APK Editor?) and understand which buid and options whoever created that APK was using. This should be only a last resort. Compiling is a lot safer, easier and faster than you might think (updating and installing to a new build only takes seconds on most computers).

    The Knox key: Read the instructions carefully. Create/use a Samsung developer acount, revoke any previous keys you may have, and get a new EDU key (it's 128 bytes long). If you can't create a key or your key is rejected, that simply means you made a mistake. Re-read the instructions and try again. Your Samsung developer account can use any email address and is unrelated to your "real" Samsung user account. After 90 days, your key will expire. Revoke it or switch to a new dev account, then get a new EDU key for another 90 days, no need to change your AdHell settings besides entering the new key when prompted.

    Remember, AdHell is basically a tool to configure the Knox firewall included with our Samsung devices (not just S10). Pick the correct block lists and settings for your personal needs, and once that's done you don't even need to run AdHell at all, not even in background, until you need to change something.
