ASK: How to disable data into aplication? - Google Pixel 3a Questions & Answers

Hey, How to disable data / internet / wifi into app?
I want to disable ads in app.
In another device, I can disable access data / internet in every app.
How to in pixel 3a?

You need to root your phone, then
- install adaway to disable ads
- install afwall+ to control internet access per app

NetGuard - no-root firewall - Apps on Google Play
A simple way to block access to the internet per application
play.google.com
This app doesn't require root to block internet access on a per app basis. In the app description, there is also the source code in case you want to make sure there isn't any malicious code.

Real Android firewall - doable? Does it exist?

DroidWall in the marketplace allows full WiFi access to all apps.
Is it possible to code an application for Android (perhaps with root access) that can:
- deny all outbound data access per app basis
- specify the rules (ip-range/port-range) per app basis
Like a real alternative to a desktop software firewall?
Way too many apps are leaking all sorts of information (in plain text!) from the user account database to the Internet.
The android security makes me really scared to use the platform for anything requiring security. The privacy/security model is basically a swiss cheese that can be poked through by almost any app that just asks for certain rights at install time.
I'm hoping a firewall would be able to limit this issue, no?
I don't know about the other stuff you mentioned, but my version of DroidWall has a block/allow option for wifi and 3g, separately. It's the latest version from the market place, 1.4.2
Thanks, I just checked it out and it seems DroidWall indeed has a Wifi side blocking by app basis as well. I'm still testing though.
Ah, just tried it. Force closes on Galaxy S (rooted). Sigh.

Is there any Android 9 custom ROM that can block network access for applications?

Let me clear that I am NOT talking about the default process by which applications ask for extra permissions or about whether an application's manifest lists the permissions it uses.
I am running the official Android Pie firmware on my Pixel. The bootloader is unlocked. I am looking for one of these two things:
An alternative firmware image ("ROM") that features the ability to block network access for individual applications. I believe that there is an Xposed module that can do this,but Xposed is not yet ready for Android Pie.
Software that, after rooting my phone, can be installed and be used to block network access for specific applications.
Why not use a firewall app, such as AFWall+ or NetGuard?
Rooted, use Android Firewall Plus to block apps
I use Android Firewall Plus on my Pixel with LOS 15.1 and Magisk. Works very well. I block every app and process that doesn't have a legitimate use for internet. I use Lineage so I can use Privacy Guard to block detailed permission for the few apps I DO let talk to the internet. Seems to work great.

Question about rooting Note 10 Unlocked

Will rooting the device help with disabling ads in apps? Ex: Instacrap(instagram)

root wont do that by itself, but root will allow you to sideload apps that will block ads on many/most apps. You can also defeat a great many ads with the built in VPN
For paid option You can use Nord vpn (not google play version though!) or for free option you can use some free adblock DNS like adguard dns to get rid of most of advertisements but, for apps like YouTube or Instagram because, the way they preview ads are different than other apps there is no option other than using their patched app which could be not as safe as their original app but, those options I said usually block most of ads in any browsers or other apps that use normal way of showing in-app advertising.

Help security/privacy question GrapheneOS (noob, beginner)

Hello everybody, i am using Graphene OS and only FOSS apps and i have a question. Recently i see some Foss apps also have "trackers" like Duckduckgo browser for example. I want to choose which apps i can block the internet connection for + the communication wich each other + VPN. I tried to use a "firewall" like netguard to block internet connection from the apps whoem don't need it + trackercontrol to block the trackers from all the apps and OpenVPN to hide my IP adress. But i can't use these 3 apps at once because the phone recognize them all as an VPN. Does anyone have the solution for this for me?
Use Brave browser.

That is only for tracking on web browsing. I am searching to block unwanted trackers on the background from the apps also
When you are on the Internet, data such as IIP address, browser type, operating system, etc.pp, are inevitably transported with. Even a VPN service - what is superior to a Proxy - get this data transmitted. And you never will really know what the VPN service is doing with these data - at least VPN services that are free-of-charge - and whether they themselves run Man in the Middle Attacks or not.
BTW: A Firewall protects a network’s resources from intrusion by users on another network such as the Internet. All networked and online Android users should implement a Firewall solution, IMO. If you have a rooted Android smartphone, you can use AFWall+ to control your device’s Internet activities. AFWall+ also allows users to control Internet access on a per-app basis.

Thabk you very much for youre great advice. So if i understand it good it is VPN connection is not a top priority right? Is it also true that GrapheneOs creates every day another imei number? Is the firewall solution of AFWall+ not the same as Netguard? If no can you please tell me what the difference is. AFWall+ gives in Fdroid that it has antifunctions, also for a lot of other apps. Does that have also influence on privacy and security?
I don't
1. make use of VPNs
2. know anything about GraphenOS. Changing IMEI and/or Wi-Fi Mac Address on a per daily basis makes no sense for me
3. use NetGuard, never tried it

[Request] (Android 10+ Root) Block/Restrict internet access +other permissions for apps

Hey, I am currently searching for an app that can completely block the access to the internet (and maybe other permissions) for specific apps.​
For a while now I have been using the original XPrivacy to block apps from accessing the internet (+other permissions) for many apps. I have been on Android 5 for a while now but now I am considering to switch to another ROM that is on Android 10 or higher.
I have already looked at XPrivacyLua, but it won't work for me, because it's not possible to restrict access to as many and detailed permissions as in the original XPrivacy, e.g: not possible to restrict internet access...
Apps the use the VPN connection to block the access won't work for me, because I use a VPN sometimes.
The only alternative and solution I have currently found is to use Permission Manager X and AFWall+
But sometimes Permission Manager X just resets the rules and won't apply them and with AFWall+ you need to select every connection type everytime, which is tedious
TLDR: Searching for apps like the original XPrivacy but for Android 10 or higher
